    at present, China is promoting the application of low-protein diet feed technology in pig, broiler and egg chicken breeding, effectively reducing the amount of soybean meal without affecting production performance and meat qualitySeveral experts interviewed by the Economic Daily said it was feasible from both a technical and economic point of viewWhile reducing the demand for soybeans for feeding, the total amount and quality of meat supply are guaranteedeHJ
    Li Defa, a member of the Chinese Academy of Engineering and president of the China Feed Industry Association, said that the so-called low protein diet technology is based on the theory of nutritional balance of protein amino acids, and reduces the protein level and nitrogen emissions by adding suitable types and quantities of industrial amino acids by adding suitable types and quantities of industrial amino acids without affecting the performance and product quality of animalsThis technology is the result of the development of modern animal nutrition, and also the embodiment of the current research on precision nutritionMore than 10 years of research and the practice of a large number of farmers have proved that low-protein diet feed technology can ensure the growth performance of animals, will not affect the quality of meat, and not only reduce the dependence on soybean imports, but also reduce environmental pollutioneHJ
    According to the introduction, the protein content in the feed is not the higher the better, but also look at the digestion rate, if not fully absorbed by animals will cause waste of resources, and low protein diet in meeting all essential amino acid content, but also balance other excess non-essential amino acidsFor a long time, the raw materials for protein provided by pigs in the feed were mainly soybean meal, while the use of other meals was relatively smallIf the use of low protein diet, the amount of soybean meal in feed can be greatly reduced, to alleviate the impact of soybean meal (soybean) raw material supply and high prices, and really reduce feed costseHJ
    "For every 1 percentage point reduction in protein levels, the amount of soybean meal used by 2.3 percentage points can be reduced"Take pig feed as an example, China's pork production in 2017 was 49.8 million tons, calculated by 4.5 percent of the material, and 224 million tons of feed, said Yan Shiyan, director of the National Feed Engineering And Technology Research Center and a professor at the School of Animal Science and Technology of China Agricultural University China's current pig production feed protein content of 16%, according to the current low protein diet technology can be promoted, the whole protein level from the current 16% to 14%, can reduce the amount of soybean meal nearly 10.3 million tons eHJ
      In recent years, due to the high dependence of soybean imports in China, and the pollution of surface sources caused by nitrogen emissions in the aquaculture industry has been paid more and more attention, so the industry has carried out a lot of research on low-protein diet formula technology Since 2006, the researchers, with the agricultural feed industry center as the main body, have studied the relevant technical points in depth, have determined the net energy value of the main pig feed raw materials, studied the amount of net energy needed in each stage of pig growth, and constructed the "Chinese pig low protein daily grain formula technical parameters" At present, the low protein diet formula technology of pigs is the most in-depth research, and carried out a certain degree of promotion and application In addition, the low protein diet technology of egg and chicken and broiler has also been studied eHJ
      Food accounts for 70 percent of the cost of scale pastures, said Hu Glacier, an associate researcher at the Institute of Rural Development at the Chinese Academy of Social Sciences Soybean meal prices rise, the market participants will adjust their own feed formula The high proportion of soybean meal used in feed is the main reason for the low price, and as the price of soybean meal rises, it will become economically feasible to choose other alternatives eHJ
      For the amount of soybean meal reduction, China's feed and breeding enterprises accumulated a lot of experience Common is the mixed meal, is to use cotton meal, vegetable meal and other miscellaneous meal to replace part of soybean meal, and supplemented by amino acids and other to improve the conversion rate of the meal feed This method has been used in recent years in the rising stage of soybean meal to reduce costs Hu said China's total meat and aquatic products production of about 150 million tons, in addition to eggs, milk and other protein supplies The promotion and application of low-protein diet technology does not affect the quantity safety of meat protein, and the cost of price is also controlled eHJ
      In recent years, China has made a lot of efforts in the promotion and application of low protein and low soybean meal, but still faces some constraints Experts believe that: First, the formation of the feed protein content to determine the quality of feed thinking habits, difficult to correct in a short period of time; eHJ
      Yan Shiyan suggested to speed up the revision of the standards of animal feed products, supplement the development of meat ducks, eggs, ducks, yellow feather chicken and other feed products standards, set a protein content limit, fully reflect the recent research results of protein amino acid nutrition At the same time, call on large-scale feed enterprises to improve the level of technology, actively promote the application of low-protein diet Agricultural technology extension institutions at all levels should strengthen the training of small feed enterprises and farmers and promote the application of new scientific and technological achievements eHJ at present, China is promoting and applying low-protein diet feed technology in pig, broiler and egg chicken farming, effectively reducing the amount of soybean meal without affecting production performance and meat quality Several experts interviewed by the Economic Daily said it was feasible from both a technical and economic point of view While reducing the demand for soybeans for feeding, the total amount and quality of meat supply are guaranteed eHJ
