The Egg – Very Nutritious, No Matter Where It's Produced

Cholesterol levels in both free-range and cage eggs were found to be lower than previously in a new study at North Carolina State University, prompting a revision in the USDA nutrition guidelines.


Eggs produced by free-range hens are often perceived by the public to be nutritionally superior to eggs obtained from layers kept in traditional battery cages. However, a recent scientific study has called this popular perception into question by finding essentially no differences in the nutritional quality of eggs produced by hens from both management systems, said the Poultry Science Association (PSA).

The findings also showed that cholesterol levels in all eggs were lower than US Department of Agriculture guidelines, prompting the USDA to review and revise downward its estimates for average cholesterol levels in eggs.

The study, 'Comparison of Fatty Acid, Cholesterol, and Vitamin A and E Composition in Eggs from Hens Housed in Conventional Cage and Range Production Facilities', appeared in the July issue of Poultry Science, a journal published by PSA. Its author, Dr Kenneth E. Anderson, a Professor in the Department of Poultry Science at North Carolina State University, collected data for the study in 2008 and 2009. The study was conducted concurrently with the North Carolina Layer Performance and Management Test (NCLP&MT), which evaluates the major commercial layer lines used in the United States.

Dr Anderson explained: "The key take-away message from this research is that an egg, no matter where it's produced, is a very nutritious product. Eggs from a range production environment did have higher levels of total fat than eggs produced by caged hens but they did not have higher levels of cholesterol. Perhaps the most striking finding was that both cage- and range-produced eggs actually have lower cholesterol levels than previously believed, which has led the USDA to lower the cholesterol guidelines for eggs in the USDA Nutrient Database for shell eggs to 185mg per egg, down from 213mg."

Research Framework

Dr Anderson conducted his study in North Carolina using more than 400 Hy-Line Brown pullets. The pullets were raised in accordance with the laying environment (range or cage) in the 37th NCLP&MT. All of the pullets in the study were hatch-mates. Identical rearing dietary programs were used for both the range and cage pullets, with the only difference being the access the latter group had to the range paddock, a common hay mixture for North Carolina comprising both warm- and cool-season forages.

Pullets designated for the range facilities were brooded on litter until 12 weeks of age and then moved to a range environment. At 17 weeks, they were then moved to one of three production range paddocks. A parallel pattern was followed for the cage hens, which were reared in a cage rearing facility, and then at 17 weeks assigned to one of three groups of laying cages. All other rearing parameters were maintained as similar as possible.

Dr Kenneth E. Anderson

Research Findings

Egg samples were collected at 50, 62 and 74 weeks of age during the productive life of the flock and sent to four different laboratories commonly used for egg nutrient analysis.

The results showed no influence of housing environment (range or cage) on egg levels of vitamin A or vitamin E. However, β-carotene levels were higher in the range eggs, which, according to Dr Anderson, may have contributed to the darker coloured yolks observed in these eggs during the study. The study also found no difference in cholesterol content between range- and cage-produced eggs.

Based on these results, Dr Anderson concluded that "a significant nutritional advantage of eggs produced by chickens housed on range versus in cages could not be established".

US Poultry Outlook – August 2011

High feed prices will curb production next year, according to the USDA Economic Research Service in its Livestock, Dairy and Poultry Outlook for August 2011.
USDA Economic Research Service
Broiler meat production increased strongly during the first six months of 2011 (up 4.8 per cent), growth in the first quarter was 6.4 per cent higher than the previous year and second-quarter production was 3.3 per cent higher than a year earlier. In the second half of 2011, broiler meat production is expected to decline as lower bird numbers offset an expected increase in average bird weights. Higher feed costs and slow growth in the domestic economy are expected to combine to reduce production.

Turkey meat production is expected to decline in the second half of 2011 as the number of birds available for slaughter decreases. Poult placements on a year-over-year basis have been lower for the last three months.

Production of table eggs in the second half of 2011 is expected to be about even with last year.

Broiler Meat Production Up Five Per Cent in June

Broiler meat production in June totalled 3.3 billion pounds, up 4.5 per cent from the previous year. The June production increase pushed total production for second-quarter 2011 to 9.5 billion pounds, 3.3 per cent higher than in second-quarter 2010. This is the fourth consecutive quarter of three per cent or more year-over-year increases in broiler meat production. In first-half 2011, broiler meat production was 18.8 billion pounds, 4.8 per cent higher than a year earlier. This year-over-year growth in broiler meat production is expected to halt in third-quarter 2011, with production estimated at 9.4 billion pounds, 1.3 per cent lower than in third-quarter 2010. Lower production is expected to continue in the fourth quarter, with production in the second half of 2011 expected to total 18.6 billion pounds, a decrease of two per cent from the same period in 2010.

Over the first half of 2011, the number of broilers slaughtered was 4.3 billion, an increase of two per cent from a year earlier. The other factor in broiler meat production growth during the first half of 2011 has been higher average live weights at slaughter. During the first six months of 2011, the average live weight at slaughter was 5.79 pounds, up 2.4 per cent from first-half 2010. In second-half 2011, the number of broilers slaughtered is expected to be down significantly from the previous year but average bird weights at slaughter are expected to remain well above the previous year throughout the second half of 2011.

The number of chicks being placed weekly for grow-out has averaged approximately 165 million during the five-week period from 9 July to 6 August. This is down over four per cent from the same weekly period in 2010. Weekly placements of broiler eggs in incubators point to continued declines in the number of chicks available for grow-out compared with the previous year. Over the last four reported weeks, the number of eggs being placed in incubators has averaged almost six per cent lower than during the same period a year earlier.

Even with relatively strong exports, the strong increases in production and a weak domestic economy have led to an increase in broiler meat stocks. Cold storage holdings at the end of the second quarter totalled 710 million pounds, 12 per cent higher than a year earlier. One factor in the increase in cold storage holdings was higher stocks of breast meat products. Breast meat in cold storage was estimated at 155 million pounds, 47 per cent higher than the previous year. Stock changes for leg meat products were mixed, with holdings of drumsticks and leg quarters up 39 and 14 per cent. Partially offsetting these increases were declines in the cold storage holdings for legs, thighs and thigh meat.

With the generally weak economy and the strong growth in production in second-quarter 2011, the estimates for ending stocks for the third and fourth quarters of 2011 were increased. The estimate for third-quarter 2011 was raised to 685 million pounds and the estimate for fourth-quarter 2011 was increased to 700 million pounds.

In 2011, wholesale prices for broiler products have generally declined compared with a year earlier. Prices for whole birds averaged 82.6 cents per pound in the second quarter of 2011 and are forecast to average 81 to 83 cents per pound in the third quarter. Even with falling production in the second half of 2011, whole bird prices are not expected to strengthen much. The forecast for fourth-quarter 2011 is only 81 to 85 cents per pound. In 2012, as lower production begins to impact stock levels, broiler prices are expected to experience some upward price pressure. However, any upward pressure is expected to also depend on a gradual strengthening of economic conditions.

Turkey Production Rises Six Per Cent in First-Half 2011

Turkey meat production during the first six months of 2011 was 2.9 billion pounds, 5.5 per cent higher than in the same period in 2010. The increase in turkey meat production was due to a higher number of birds slaughtered, up 4.6 per cent, along with an increase in live weights at slaughter. Over the first six months of 2011, live turkey weights averaged 30.1 pounds, up 1.1 per cent from the same period in 2010.

The forecast for turkey meat production in the second half of 2011 is 2.9 billion pounds, down slightly – less than one per cent – from the same period in 2010. The decrease in turkey meat production is expected to come chiefly from a smaller number of birds slaughtered, as average live weights at slaughter are expected to continue slightly higher than those of the previous year.

Over the first six months of 2011, the number of turkey poults placed for grow-out totalled 139 million, up less than one per cent from the same period in 2010. However, on a year-over-year basis, poult placements have been lower than the previous year over the last three months.

After declining on a year-over-year basis for the previous seven quarters, turkey stocks at the end of second-quarter 2011 were 510 million pounds, marginally higher than the previous year. Although turkey meat production is expected to be lower in the second half of 2011 than the previous year, turkey stocks are expected to remain above their year-earlier levels through the end on the year.

At the end of second-quarter 2011, whole birds stocks totaled 271 million pounds, down three per cent, and stocks of breast meat were 72 million pounds, eight per cent lower than the previous year. However, any explanation of changes in turkey stocks is complicated by the fact that 148 million pounds of the cold storage holdings are in categories labelled ‘other’ and ‘unclassified.&sdquo;

Stocks of whole turkeys are still lower than the previous year, and the number of birds slaughtered in the second half of 2011 is expected to be lower than the previous year. Both these factors point to continued strength in prices for whole birds. Prices for whole hens in second-quarter 2011 were $1.00 per pound, and the price for third-quarter 2011 is forecast at $1.04 to $1.08 per pound. Prices are expected to strengthen ever further in the fourth quarter to $1.06 to $1.12 per pound, slightly higher than the previous year.

Egg Production Rises in First-Half 2011

In the first half of 2011, production of table eggs was 3.3 billion dozen, up about one per cent from first-half 2010. However, production of hatching eggs fell by 0.7 per cent compared with the previous year. The decrease in hatching egg production was chiefly the result of the gradual decline in broiler chick production for grow-out. Hatching egg production in the first half of 2011 was 532 million dozen. Production of table eggs in the second half of 2011 is expected to be about even with the previous year, and production is expected to be lower on a year-over-year basis in the first two quarters of 2012. Production of hatching eggs, especially those from meat-type birds, is expected to decline in the second half of 2011 as broiler chick production continues to be below the previous year.

Even with higher table egg production in second-quarter 2011, prices for eggs remained strong and averaged almost $1.07 per dozen, up 24 cents from second-quarter 2010. With little or no growth expected in the second half of 2011, prices are expected to be above the previous year in third-quarter 2011 at $1.04 to $1.08 per dozen. However, with the weak economy, egg prices in fourth-quarter 2011 are expected to be lower than the previous year at $1.12 to $1.18 per dozen. The weak economy is expected to provide less of a seasonal boost in prices than in other years.

Impacts of Nutrition on Health and Welfare Explored

Studies on the effects of feeding and nutrition on poultry health and welfare formed a common theme at this year's WPSA UK Branch Meeting in Nottingham in April. Jackie Linden, senior editor of ThePoultrySite, reports.


Lameness in poultry is a major concern for the industry due to its negative implications for both bird welfare and productivity levels, explained Fiona Short of Nottingham Trent University in the introduction to her paper reporting two experiments looking at the effects of a novel form of dietary silicon supplement in reducing lameness in poultry (1).

The results of the first indicated that the supplement has the capacity to reduce lameness in broilers and hence silicon may have a role in improving bird welfare. Using the highest level of inclusion (1,000ppm), clearly fewer birds were unable to stand than the other treatments and more of them stood without encouragement. The second trial demonstrated that the silicon was easily absorbed as the serum silicon concentration was dose-dependent. Overall, the researchers concluded that the novel form of silicon supplementation has high bioavailability. Larger-scale studies are needed to substantiate its potential role as a commercial supplement for reducing the incidence of lameness in broilers, they added.

Bristol University scientists have been examining the possibility of using diets with additional ω-3 fatty acids as a means to improve bone strength and reduce keel bone fractures in laying hens. These fractures are a significant welfare issue, explained Dr Michael Toscano, as evidence has been found of new or old breaks in up to 70 per cent of free-range hens (2). Early research with diets containing short-chain ω-3-enhanced diets were effective in reducing keel bone fractures but they also adversely impacted egg production.

In experimental pens, 23-week-old layers were given one of four diets ranging in ω-3:ω-6 ratio between 0.12 and 1.35, with the ω-3 source being a mixture of flaxseed and salmon oils.

There was no treatment effect on the presence of keel bone fractures, and the number of poor quality shells was found to correlate positively with ω-3:ω-6 ratio in a dose-dependent manner. Looking at the Campylobacter concentration in the caecum, the Bristol researchers found a treatment effect of a parabolic nature and a peak at 0.36 ω-3:ω-6 ratio.

Dr Toscano said the data indicate that some of the long-chain ω-3 diet's negative impacts, e.g. poor egg quality, can be alleviated while sufficient ω-3 egg yolk quality is maintained by providing a mixture of short- and long-chain ω-3 content. Benefits of mixed ration to bone and overall health issues are less clear and require further research, he added.

Wet litter is a multifactorial problem, which has implications for welfare as well as carcass quality issues owing to the links with foot and leg problems and breast blisters in poultry. Soybean meal has been identified as a cause of wet litter. The aim of a study by M.W. Mirza of SAC, presented by Dr Vasil Pirgozliev, was to gain understanding of the relative importance of the protein and potassium in soybean meal on water intake and excretion by turkeys (3).

The results of the study indicate that it is the protein rather than potassium that is the main driver of water intake in turkeys. Dietary potassium may influence water output but the effect of crude protein is more pronounced.

Turning to the effects of feeding on health, researchers at Scottish Agricultural College (SAC) looked at the impact of feed withdrawal on sub-clinical necrotic enteritis. The withdrawal of antimicrobial growth promoters has been accompanied by a resurgence in sub-clinical necrotic enteritis, a disease caused by Clostridium perfringens, explained G. Saleem and colleagues (4). Field evidence indicates that subclinical necrotic enteritis occurs after some disruption to feeding, such as a failure in the feeder system.

The results from SAC showed that the duration of feed withdrawal imposed in the present study did not predispose the birds to necrotic enteritis, with no specific lesions observed and the C. perfringens count in the digesta was low. Feed withdrawal alone does not appear to predispose birds to necrotic enteritis.

Novel Feeds and Additives

There have been a multitude of studies investigating the effects beta-glucanase in broiler diets but the use of this feed enzyme for laying hens has been neglected, according to Dr Helen Masey O'Neill of AB Vista Feed Ingredients, reporting a trial carried out in China (5).

Feeding different levels of beta-glucanase to laying hens from 19 to 48 weeks of age in a diet based on wheat and barley and fed as mash, she and her co-authors concluded that beta-glucanase supplementation can improve the laying performance of hens. In each phase of the trial, laying rate and egg mass were significantly higher for the enzyme-supplemented groups than the for the control (P<0.05). However, they noted that, while the benefit of the enzyme was noted within the first 10 weeks of the start of the study, the FCR benefit took considerably longer to develop. Furthermore, the scale of the response to the enzyme seemed to increase with time, in terms of egg mass, laying rate and FCR.

These birds were fed one diet consistently throughout the study. It is possible that more consistent results in egg weight and FCR may be achieved if diets were formulated on a phase basis, added Dr Masey O'Neill.

The rising production of biofuels in the European Union has prompted interest in altering the bio-refining process to improve the nutritive value of the co-products, said Dawn Scholey of Nottingham Trent University, reporting part of her PhD thesis (6).

She and her co-authors fed to broilers from day-old to 15 days of age wheat and soya-based diets containing zero, three, six or nine per cent of two fermented wheat co-products, one from a potable alcohol source and one from a bioethanol source.

Both yeasts increased broiler weight gain at the lower inclusion level. The researchers noted an increase in digesta viscosity for the product from potable yeast production, which could limit its use as a feed ingredient and so they concluded that the yeast derived from bioethanol production appeared to provide a viable alternative protein source for broiler starter diets.

From the University of Developmental Studies in Ghana, H.K. Dei reported an evaluation on the nutritive value of Icacina oliviformis seed meal in broiler diets (7). He explained that I. oliviformis is commonly known is the false yam and that it is a drought- and fire-resistant shrub that grows widely across the savannah regions of West and Central Africa. Its high starch content indicate that Icacina may be a suitable substitute for maize in broiler diets.

The seeds were fed either raw or after processing by boiling or soaking and then drying. Health status of the birds was not affected by treatment and the researchers concluded that processing Icacina seeds by soaking in water improved its nutritive value for broilers up to 100g/kg in the diet.

International Egg and Poultry Review: Russia

RUSSIA - This is a weekly report by the USDA's Agricultural Marketing Service (AMS), looking at international developments concerning the poultry industry. This week's review looks at the poultry meat industry in Russia.

Prime Minister Putin announced on 22 July 2011 a reduction of 2012 pork and poultry tariff quota quantities followed by the signing of a government of Russia (GOR) Resolution on 27 July and released on 29 July 2011. The 2012 tariff-quotas for fresh and frozen beef are in line with GOR Resolution #1021 of 16 December 2009.

For 2012, Prime Minister Putin stated that "Chicken production is expected to increase 330,000 metric tons (MT) next year and pork imports will be substantially reduced because we expect to increase pork output".

The 2012 tariff-quota for poultry divides the 2011 poultry tariff quota between boneless and bone-in parts for the first time. The net 2012 poultry tariff-quota is a 20,000-metric ton (MT) reduction from 2011 and 220,000MT from GOR Resolution #1021 of 16 December 2009. The 2012 tariff-quota for pork and pork trimmings represents a 150,000-MT reduction from 2011 and 100,000MT below levels stated in GOR Resolution #1021. Of notable interest is the pork trimming tariff quota for 2012 remained largely unchanged.

For 2012, poultry and pork imports within quota will be subject to a 15 per cent customs duty and a 75 per cent excess quota customs duty. Another first for 2012 in Resolution #616 no country specific allocations were indicated.

The Former Soviet Union-12 (FSU-12) Region ranked number four in US broiler meat exports and number 9 in turkey meat exports for January-May 2011. On an annual basis, Russia's share of the US FSU-12 broiler meat exports dropped from 89 per cent in 2000 to about 55 per cent in 2010. Meanwhile, Russia's share of FSU-12's US annual turkey meat exports has dropped from 98 per cent in 2000 to 51 per cent in 2010.

Animal Husbandry in China and India

ANIMAL HUSBANDRY IN CHINA AND INDIA 1
RALPH W. PHILLIPS
United States Department of Agriculture
THERE are several reasons why our thoughts turn to livestock affairs in ther parts of the world. First, there is the inquiring mind of the scientists, always seeking well-rounded knowledge of a subject. Even now, our
knowledge of animal types and husbandry in some parts of the world is very limited. Second, there is our desire to take advantage of any superior types that might be useful to us, particularly in some of our less favorable environments.
The use of zebu cattle in our subtropical regions is an example of this, and the possibilities along this line are far from exhausted. Finally, there is our interest in that multitude of problems that must be solved if the people
of the world are to have an adequate diet and ample clothing. There is no need of recounting the importance of livestock in providing meat, milk, skins and fibers for those purposes. Some well-meaning persons have told us, in recent years, that the people of the world, and particularly, of the United States, are to become more dependent on cereals and will necessarily consume less meat. So long as populations continue to grow, food must be had for them. So it is possible that a larger portion of the world's supply of grain may have to be used for human consumption and less for livestock. But it must be remembered that only a relatively small portion of the earth's surface is cultivated. Of the remainder, some is entirely unfit for food production
and a little can yet be brought under the plow, but the major portion that is useful in food production is land from which only livestock can harvest a crop. Our own extensive grasslands are utilized rather fully, but similar vast areas in the world are making little contribution to the world's food supply, other than by the maintenance of small nomadic and semi-nomadic populations.
When our thoughts turn to China and India, no doubt many of us think of rice-eating millions and wonder about the importance of livestock in these countries. Using figures for about i94o , and making due allowance for the inadequacy of some of the statistics, we can obtain a rough approximation of livestock numbers, expressed as the numbers per ioo such animals in the United States. China, on this basis, has 6o horses and ~o5 mules. We have so few jackstock that they ar~not listed in our statistics, but China has over 9.5 million
donkeys and jackstock. These, combined with the horses and mules, bring 1 Presented as part of a symposium on "A World.Wide View of Animal Husbandry" at the opening session of the annual meeting of the American Society of Animal Production in Chicago, on November a9, 1946. China's estimated total equines to I4O, in comparison to ~oo here. For cattle, the figure is 35. Add to this approximately i i. 5 million water buffaloes, and the bovine population is 5o compared with Ioo in the United States. Also, there are large yak and yak-cattle hybrid populations on the Tibetan plateau and the southern edge of the Mongolian plateau for which no figures are available. China has 35 sheep, 5o5 goats, and I~5 swine per ioo here. China also has many camels. There are about Ioo,ooo in Ningsia and the Manchurian provinces, but no figures are available for other provinces where camels are used. Outer Mongolia has not been included in any of the above comparisons. The land area of China, exclusive of Outer Mongolia, is about ~5 percent of that of the United States. India has only about 53 percent of our land area. Her equine population includes ~5 horses and ~ mules per ioo here, and somewhat over two million donkeys, bringing the proportion of equines to 3o. In cattle, India exceeds us with ~5. There are also 45 million water buffaloes, so that the total bovine pol~ulation is over 2oo million, or about ~9o animals per ~oo in the United States. Proportions for sheep are 9o, and for goats I4oo. Swine are of little importance, the proportion being less than 4 per ~oo here. There are also about i. i million dromedaries or one-humped, camels and there are some yaks and yak-cattle hybrids in the Himalayan foothills. These figures indicate the obvious importance of livestock in the agricultural economies of both China and India. How do these animals fit into the scheme of things on the farms and in the grasslands?
The place of livestock in any country is related intimately to the mode of living of the people. Mode of living is in turn closely associated with geographic and climatic conditions, and with pressure of populations. In China,
there is a wide variety of conditions, and there are two main modes of living among the rural populations, characterized by the settled farmers of the eastern and southeastern parts of the country, and the nomadic and seminomadic peoples of the northern, western, and northwestern portions. There are also variations in racial stocks which affect the utilization of animals. China is primarily a land of mountains. Level land is found only along some river valleys, in delta regions and in a few other areas. I have mentioned that the settled farmers live in the eastern and southeastern parts of the country. This area of intensive farming is divided into two main regions, the rice region south of the Chingling Mountains, and the wheat region north of these mountains. Millet and kaoliang are also important grain crops in portions of the so-called wheat region. In both the ~ice region, where much of the tilled land is flooded, and in the dry wheat region, terraced hillsides are the rule. In both areas, farms are small, averaging a little over 3 acres in the rice region and about 5-5 acres in the wheat region. In both areas, the average farm is broken into about 5.6 parcels of land. Everywhere in the farming regions there is an oversupply of people and an undersupply of land, so that every available plot of soil is pressed into use for the production of human food. Under these conditions, livestock serve chiefly as work animals and scavengers, and as users of the few available by-products. Even so, a large livestock population is maintained. The farming regions are occupied chiefly by people of Chinese racial stock. The farmers in the south use the water buffalo as the chief draft animal in rice fields. Cattle, small native ponies and some donkeys are used for packing and for draft on mountain farms where rice cannot be raised. Few sheep are raised in the rice region, except in remote mountain areas. Goats are found everywhere and provide meat and hides. Little milk is used by Chinese, either from goats, or from cattle and water buffaloes. Pork is the favorite meat, even though the average Chinese gets little of it. The richer farmers keep breeding sows, and pigs are raised by as many farmers as can afford to buy them and can find enough feed. They are kept chiefly as scavengers, turning vegetable refuse into manure for the fields, until Iz to x8 months of age or older. They are then fattened rather quickly by the wellto- do farmers who have surplus grain or by sugar factories and distilleries where by-products are available.
Owing to lack of refrigeration, pork and other meats must be sold within a short time after slaughter. The common practice is to begin slaughtering about midnight, so that meat will be in the open-air retail markets by daybreak the following morning. Bristles have been one of the important byproducts of Chinese pigs, but the rapid development of synthetic bristles probably will reduce their importance. Next to pork, goat meat is most important in the Chinese diet. Some beef is eaten, mostly from worn-out cattle and water buffaloes. But there is considerable prejudice against eating the meat of a beast that has served faithfully in the fields for most of its life. There are practically no water buffaloes in the wheat region, north of the Chingling Mountains. Packing and draft work on farms is performed by cattle, horses, donkeys and mules. Horses and mules are used for draft on highways, where highways exist. Horses in this region are of the Mongolian type, much larger than ponies of the South, but still only ~z to ~4 hands high. Excellent mules are produced by mating such mares to the jacks of similar height from Shensi and Shansi. Swine in the wheat region are longer and less rotund, and are generally solid black, in contrast with the fatter animals, often with white markings, in the rice region. Sheep are more important in the wheat region, where there is considerable suitable grazing land. The goat is ubiquitous in China.
Chinese farmers have penetrated into the edges of the adjacent grass lands, wherever tillable land could be found, using land that should be reserved for producing winter feed for range livestock. But they are tillers of
the soil, not animal husbandmen. So the management of livestock on the grasslands has been left to people of other racial stocks; Tibetans in the Tibetan Plateau, Mongols in the grass lands of the North, and Kazakhs and
other groups in the Northwest. Mohammedans constitute an important group in northwestern Kansu, parts of Chinghai and Ningsia, and Sinkiang. They are not a distinct racial group but include Turkish, Mongolian and
Arab stock, mixed with Chinese, as well as some Kazakhs and others that adhere to this religion. Naturally, there is little interest in pork production in this region, quite apart from the fact that there is little suitable feed.
Sheep provide the foundation for existence in most of the grassland areas. Mutton is the most important meat. Wool is made into clothing, blankets, rugs and felt. The felt is used for boots and to cover the movable yurts in
which many Mongolians and some others live. Pelts of young sheep are used to line gowns to give protection from cold winter winds. Some skins are made into leather. Inflated sheepskins are bound together to make rafts that are used on Yellow River. Droppings are collected at night in corrals and used as fertilizer and fuel. Some sheep milk is used as human food. Wool is sold, going chiefly, in prewar days, into the carpet wool supply of the United States, to obtain cash for purchase of the few manufactured articles used in the simple life of the nomad. In the Tibetan grasslands, yaks vie with sheep for first place in economic importance. They are used for milk production and as pack animals, and to a limited extent for riding and draft purposes. Their long hair is used for making cloth for tents, and the finer undercoat is used in other fabrics. Animals are herded on the high mountains during the late spring, summer, and early fall, and are kept in the valleys in winter. During the good grazing season, butter and dried casein are prepared and stored for winter use. These and barley flour are major items in the winter diet of the Tibetan. Rancid batter is mixed with tea to make the favorite beverage. It is also used as cold cream to give protection from the wind, as "clay" for extensive sculpturing
for religious ceremonies, and as fuel in the candle pots of the lamasaries. Hybrids between yaks and cattle are also produced, and are larger, stronger pack animals and better milk producers than yaks, but they do not have the stamina and ability to exist under very rigorous conditions that are possessed by the yak. Yaks and yak-cattle hybrids are also important among the Mongols in the higher regions of Kansu and Inner Mongolia.
Cattle are also found throughout the grassland area, except at the higher elevations where only the yak can thrive. They are mostly of the Mongolian type and produce somewhat more milk than the cattle in the Chinese
farming regions. Even so, two quarts is a good daily production, if one leaves enough to keep the calf alive as a necessary stimulant to letting down of the milk at each milking. Few donkeys are found in the .open grasslands. Here, Mongolian horses provide the chief means of transportation, other than that provided by yaks in the uplands and by camels in the lower, drier areas. The camel is used chiefly in the winter. Herds of these animals are taken to the uplands for grazing during the summer, so that their humps fatten and stand erect, proriding stored food to help them through the lean winter days of caravan duty. Animals as yet have flo real competition in the carrying of freight in upland Asia. In the fanning regions, the only real competition is provided by man himself, and by small boats propelled by man on the inland waterways. India and China have had little interchange of stock and ideas in their development. The natural barrier provided by the Himalayas and their extension to the south in Burma, popularly known as "The Hump," have prevented any such interchange, yet there are many similarities. Both countries are characterized by over-population and the resulting problem of inadequately small farms. The majority of the people in the fanning regions of both countries are dependent upon a cereal diet. In India, 75 percent of the cultivated land is devoted to cereals, principally rice and wheat. Both countries have considerable areas devoted to grassland production of livestock. In India, these regions are chiefly in the drier portion of the northwest, and in the low mountain country in the south. As in China, there are racial differences which have their effects on livestock utilization, such as the Hindu's reverence for the cow, and the Moslem's abhorrence of pork. The whole structure of Indian agriculture is based upon the use of bullocks and other cattle for draft purposes. Cattle also furnish much of the power for highway transportation in rural areas, and a considerable amount even in large cities. Most native breeds are used solely for draft, but some types, such as the Sahiwal, Red Sindhi and Gir produce fair amounts of milk. In animals of the latter breeds, milk yields of four to five thousand pounds per lactation are rather common, and under the best of conditions, yields of ten thousand pounds or more are sometimes obtained. The majority of the people are Hindus and eat no meat, hence milk and milk products
provide most of the animal protein. The average Indian rice-eater's diet is inadequate, in comparison with the optimum requirements laid down by our National Research Council. For several important constituents, the
rice-eater consumes the following amounts, expressed in percent of the optimum: Calories, 58; Total protein, 54; Animal protein, 3; Calcium, 2o; Iron, 75; Vitamin A, io; Vitamin B1, 27; Vitamin C, 20. Obviously, livestock make little contribution to this diet, other than to provide the power for till/ng the fields upon which the food is raised. In areas where cattle breeding is an important pursuit, the milk consumption including ghee, or clarified butter, curd and other milk products is higher, averaging about ten ounces per person daily, according to results of one survey. With her huge cattle population, India has a host of problems, including
how to reduce numbers of bullocks to those actually needed for work, how to overcome opposition to castration of scrub bulls in villages where improved bulls are placed, how to eliminate wasteful maintenance of thousands of diseased, crippled and otherwise useless cattle in ping-rapoles or old-cattle homes, how to salvage the thousands of good cows and water buffaloes that are shipped into city dairies, milked to the end of a lactation and slaughtered, how to find a substitute fuel so manure can go on the land instead of being
burned, to mention a few. The water buffalo is the chief milk producer in India. Herds of animals of the Murrah and related breeds of the plains of north central India often produce about four thousand pounds of milk, with about 7. $ percent fat, perlactation.
The numbers of horses, mules and donkeys already given indicate the small importance of these types. Horses and ponies are of most importance in the grassland regions of the northwest and in the Himalayan foothills. The donkey and mule are generally held in low regard. Camels (dromedaries) are used extensively for packing in the northwestern portions of the country, and to some extent for draft also, around cities like New Delhi. Goats are found in all parts of India. They vary in size from the miniature animals of Bengal to the large Jumna Pari breed of north central India. Many are milked but little has been done to improve milk-producing qualities. They provide meat for the Moslem and other flesh-eating portions of the population, and also skins for leather. Long-haired types in the Kashmir area provide some fiber for textiles. Several types of sheep are produced in the drier areas adapted to sheep production. These include the fat-tailed sheep with very coarse wool in the northwestern regions adjacent to Afghanistan, and thin-tailed types that pro:luce wool of somewhat better quality, in other portions of northern and northwestern India and in some sections of southern India. There is also a brown hair sheep in southern India that is used for meat and skin production. Some sheep are milked and ewes of the Lohi breed are reported to give as much as eight pounds daily at the peak of lactation. The milk is rich in fat, and some is mixed with milk from cows and buffaloes for making ghee.
Swine are of little importance. In villages where they are raised, they serve chiefly as scavengers, often living to a considerable extent on human feces. There was a temporary boom in pork production during the war, owing to the presence of many foreign troops in the country. Close economic ties exist between our western grasslands, the midwestern feeding areas, and the meat-consuming population centers in the East. Such economic ties have not been developed in China and only to a limited extent in India. In China, there are movements of working animals from the mountain grasslands to the farms in lower areas withir; the fanning regions, of Mongolian horses from the grasslands into the wheat,farming region, and limited amounts of wool and hides find their way from the grasslands into commerce, but in general, the farming and pastoral economies are as distinct as in the days when a Great Wall was built to keep them apart.
In India, working bullocks move from the grazing areas of Baluchistan, Northwest Frontier Provinces and the Punjab to the farming areas in the north central plains; buffalo and zebu cows move from country districts into
city dairies; wool and hides move from the graz/ng areas into trade channels, but there is not the fullest development of economic ties between the pastoral and farming economies. Neither is there the large demand for livestock products among the Hindu population that is necessary to development of close economic ties.
Obviously, this is only a glimpse at the immense animal industry of either country. Much could be said of the many varied breeds and types of livestock that are found in Ch/na and India. But that could not be adequately
done without including many pictures, and such descriptions have already been given in several publications issued during recent years on Chinese and Indian livestock (see Literature Cited). But there is one point that I wish to emphasize. If one examines the photographs in the publications mentioned, most of the types of animals found in both countries may appear quite unimproved. And they would be so under Corn Belt or other near-ideal conditions. But it must be remembered that rice straw is first-class roughage for livestock in the farming areas of both Ch/na and India, that animals must pull through the winter on very poor rations in the grassland areas where little feed is put aside for their use, and that under conditions there our improved breeds often could not survive, much less produce at satisfactory levels. Until economic conditions, education, and other factprs make possible the better feeding and management of livestock in those countries, the first measure of performance is ability to survive, coupled with only as much productivity as the land will support.
Relatively few well-trained workers are available in either China or India to assume leadership in livestock and range and pasture improvement. This does not mean that they are without good men, for each country has a handful of well-trained technical men working in various phases of animal industry. Most of the leaders have had advanced training in this country or Great Britain, and in neither place, with few exceptions, have they learned the all-important lesson of breeding animals adapted to the local environment. Too frequently, they have seen fat rams and bulls and sleek dairy animals kept under the best of conditions, and have as their main objective the transplanting of such animals to their native countries. The fallacy of such an approach, at least in many circumstances, is illustrated by the results of grading up with foreign dairy breeds, mostly Holstein, in tropical India. 
Records are available on animals having from ~ to ~ imported blood. The production trend begins with 4839 pounds in animals with ~ imported blood, rises to about 698o in the ı89a nd ~ groups, and drops to 618o in animals with ~ imported blood. These are animals that have been kept for the most part in military dairies and governmental experiment stations, and have had much better care than could be expected in native herds. Animal husbandry and all other agricultural education is also limited by the fact that most of the men who have sufficient wealth to attend college have never worked on the land or with livestock and so do not have a full appreciation of their own animal industry and its problems. One final point. Do we have an interest in the improvement of livestock production in underdeveloped countries such as China and India? I believe we do. And the answer seems to me to be the same, whether we look at this problem strictly from the humanitarian side, or entirely from the selfish side of guarding and improving our own well-being and our position among the peoples of the world.

Great Facts on Pork

Following text give you reasons why Allah (SWT) has forbidden eating pork.
There are many other reasons which we do not know of but ALLAH (SWT) knows.
"You are what you eat" - Native American proverb
In folklore terms, eating the meat of the pig is said to contribute to lack of morality and shame, plus greed for wealth, laziness, indulgence, dirtiness and gluttony/excessiveextreme.
Muslims are forbidden by God to eat the meat of the pig (pork).
The Jews and Christians are also forbidden from eating pork.
Here is a quote from the Old Testament to that effect: "And the swine, because it divideth the hoof, yet cheweth not the cud, it is unclean unto you: ye shall not eat of their flesh, nor touch their dead carcase." Deuteronomy 14:8
Many Christians believe that this verse was directed only at the Jews. But Jesus himself says during the Sermon on the Mount; "Think not that I am come to destroy the Law, or the Prophets: I am not come to destroy, but to fulfill."
Many Far Eastern traditions also discourage the eating of pork. The 3,000 year old Confucian Book of Rites says, "Agentleman does not eat the flesh of pigs and dogs." 
Bad effects of pork consumption
Pig's bodies contain many toxins, worms and latent diseases.
Modern veterinarians say that pigs are far more predisposed to these illnesses than other animals.
This could be because pigs like to scavenge and will eat any kind of food, including dead insects, worms, rotting carcasses, excreta (including their own), garbage, and other pigs.
Influenza (flu) is one of the most famous illnesses which pigs share with humans. This illness is harbored in the lungs of pigs during the summer months and tends to affect pigs and humans in the cooler months. Sausage contains bits of pigs' lungs, so those who eat pork sausage tend to suffer more during epidemics of influenza. Pig meat contains excessive quantities of histamine and imidazole compounds, which can lead to itching and inflammation; growth hormone, which promotes inflammation and growth; sulphur-containing mesenchymal mucus, which leads to swelling and deposits of mucus in tendons and cartilage, resulting in arthritis, rheumatism, etc.
Sulfur helps cause firm human tendons and ligaments to be replaced by the pig's soft mesenchymal tissues, and degeneration of human cartilage. Eating pork can also lead to gallstones and obesity, probably due to its high cholesterol and saturated fat content. The pig is the main carrier of the taenia solium worm, which is found it its flesh. These tapeworms are found in human intestines with greater frequency in nations where pigs are eaten. This type of tapeworm can pass through the intestines and affect many other organs, and is incurable once it reaches beyond a certain stage. One in six people in the US and Canada has trichinosis from eating trichina worms which are found in pork.
Daging Babi
            Babi adalah hewan yang banyak mengandung parasit dan bakteri yang membahayakan. Babi merupakan faktor terbesar yang menimbulkan segala penyakit pada manusia. Parasit dalam daging babi ;
  1. Cacing Pita ( Taenia solium ): Cacing pita panjangnya dapat mencapai sepuluh kaki. Menyedot makanan yang sudah dicerna, mengakibatkan kekurangan darah ( anemia ), gangguan pencernaan, dan diare. Manusia dapat mengetahui jenis cacing ini dalam usus-usus mereka oleh gejala histeria dan mudah kaget. Larva ini merambat dari usus menuju peredaran darah ke berbagai organ tubuh, khususnya otak, hati, jaringan saraf tulang belakang, paru-paru, dan sendi-sendi.
  2. Cacing Spiral ( Trichinella spiralis ): Cacing ini berdiam dalam sendi-sendi tubuh, sekat rongga, dan ruang lain dalam jasmani manusia. Dalam sekat rongga kadang mengakibatkan nafas terhenti.
  3. Cacing Schistosoma japonicum. Sangat berbahaya. Manusia akan terjangkiti bila menyentuh atau madi dengan air yang sudah tercemar dengan larva-larva cacing ini atau kotoran babi. Larva cacing itu masuk melalui pori-pori kulit, merambat ke aliran darah, paru-paru, dan hati. Dalam satu hari, cacing ini dapat memproduksi lebih dari 20.000 sel telur.
  4. Fasciolepsis buski: Hidup dalam usus-usus halus babi. Parasit ini meninggalkan usus-usus melalui tinja. Ia akan berdiam diri dalam genangan air yang akan menjangkiti manusia dan menyebabkan gangguan alat pencernaan dan diare. Setelah itu kadang terjadi pembengkakan di seluruh tubuh.
  5. Cacing Ascaris : dapat mencapai 10 inci. Menyebabkan gejala radang paru-paru, sesak pada limfa udara, dan penyumbatan pada usus.
  6. Cacing Ancylostoma duodenale: Jenis cacing ini masuk ke dalam tubuh melalui pori-pori kulit, mandi, maupun meminum air yang sudah tercemar.
  7. Clonorchis sinensis :Jenis cacing penghisap. Merupakan sumber infeksi tubuh manusia.
  8. Cacing Paru-Paru ( Paragonimus ): Belum ditemukan cara membasmi atau membunuh cacing tersebut dalam paru-paru babi. Terdapat hanya di habitat babi. Parasit ini menyebabkan manusia mengalami pendarahan paru-paru basah.
  9. Erysipelothrix rhusiopthiae: Terdapat pada kulit babi. Bila masuk ke pori-pori kulit manusia, menyebabkan gejala radang kulit. Dikenal dengan bercak merah.
  10. Beberapa bakteri dala daging babi antara lain ; Tuberculosis ( TBC ), Cacar ( Small Pox ), Kudis ( Scabies), Kumparan Kuman-Kuman ( Rusiformas N ), Kolera ( Salmonella choleraesuis ), Balantidium coli (gejala disentri), Mikrob Brucellosis, (gejala demam malta fever), Mikrob Toxoplasma gondii (Menulari manusia melalui makanan yang sudah tercemar kotoran babi atau menghirup debu beterbangan yang mengandung bakteri ini).

Daging babi paling banyak mengandung parasit dibanding daging hewan lainnya yang dikonsumsi manusia. Sebagian besar bakteri dan parasit dalam babi dapat membunuh manusia. Jenis cacing yang ada pada daging babi menjadikannya sebagai persinggahan perantara karena hanya dapat hidup terus di dalam tubuh manusia yang dianggap sebagai persinggahan terakhir. Daging babi adalah daging yang sulit dicerna karena mengandung banyak lemak. Selain itu juga menyebabkan banyak penyakit, seperti pengerasan pada urat nadi, naiknya tekanan darah, nyeri dada yang mencekam ( angina pectoris ), dan radang persendian.
Suatu praktik uji coba telah dilakukan pada tiga potong daging babi, daging domba, dan daging sapi yang seumur kita jemur di terik matahari, apa yang akan terjadi? Daging babi akan membusuk lebih cepat daripada daging domba dan sapi. Terkadang daging sapi menjadi kering dan tidak mengalami kerusakan, tetapi menjadi dendeng. Untuk dapat dicerna dengan sempurna, daging babi membutuhkan waktu lebih dari lima jam. Daging babi juga tidak mengandung banyak nilai gizi. Daging babi banyak membawa mengandung senyawa pro kanker

“ISLAMIC METHOD OF SLAUGHTERING ANIMALS IS BETTER”


Al Shaddad Bin Aous has quoted this tradition of the Holy Prophet (P.B.U.H.) "God calls for mercy in everything, so be merciful when you kill and when you slaughter, sharpen your blade to relieve its pain". Many allegations have been made that Islamic slaughter is not humane to animals. However, Professor Schultz and his colleague Dr. Hazim of the Hanover University, Germany, proved through an experiment, using an electroencephalograph (EEG) and electrocardiogram (ECG) that *Islamic slaughter is THE humane method of slaughter* and captive bolt stunning, practiced by the Western method, causes severe pain to the animal. The results surprised many.

EXPERIMENTAL DETAILS
1.      Several electrodes were surgically implanted at various points of the skull of all animals, touching  the surface of the brain.
2.      The animals were allowed to recover for several weeks.
3.      Some animals were slaughtered by making a swift, deep incision with a sharp knife on the neck cutting the jugular veins and carotid arteries of both sides; as also the trachea and esophagus (according to Halal Method).
4.      Some animals were stunned using a CBP humane slaughter by the western method.
5.      During the experiment, EEG and ECG were recorded on all animals to record the condition of the brain and heart during the course of slaughter and stunning.

RESULTS AND DISCUSSION

Halal Method

1.      The first three seconds from the time of Islamic slaughter as recorded on the EEG did not show any change from the graph before slaughter, thus indicating that the animal did not feel any pain during or immediately after the incision.
2.      For the following 3 seconds, the EEG recorded a condition of deep sleep - unconsciousness. This is due to a large quantity of blood gushing out from the body.
3.      After the above mentioned 6 seconds, the EEG recorded zero level, showing no feeling of pain at all.
4.      As the brain message (EEG) dropped to zero level, the heart was still pounding and the body convulsing vigorously (a reflex action of the spinal cord) driving maximum blood from the body: resulting in hygienic meat for the consumer.

Western method by C.B.P. Stunning

1.      The animals were apparently unconscious soon after stunning.
2.      EEG showed severe pain immediately after stunning.
3.      The hearts of the animal stunned by C.B.P. stopped beating earlier as compared to those of the animals slaughtered according to the Halal  method resulting in the retention of more blood inthe meat. This in turn is unhygienic for the consumer.
