Shelf cattle: Shelf cattle that are fattened (about 300kg in weight) in the cowshed, the proportion of protein feed in the diet can account for 10% to 13%. After gradually increasing body weight, the content of protein feed in the diet can be reduced. By the end of fattening, the content of protein feed can account for 10% of the diet. Agricultural Raw Materials refers to a small amount or trace substance added in the process of feed production and processing and use, which has a small amount but significant effect in feed.Agricultural Raw Materialss are the necessary raw materials used in modern feed industry, which have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost and improving the quality of animal products.Agricultural Raw Materialss are divided into microbial Agricultural Raw Materialss and Chinese herbal Agricultural Raw Materialss.Among them, microbial Agricultural Raw Materials is a kind of microbial products that replace or balance one or more bacterial strains in animal ecosystem.In a narrow sense, it is a kind of microbial products that can stimulate the growth of beneficial bacteria and resist the growth of harmful bacteria.Microbial Agricultural Raw Materialss containing a large amount of beneficial bacteria (active lactobacillus, bifidobacterium, bacillus), compound Enzyme, chelating peptide, mildew remover, etc., as the inside of livestock and poultry feed, can rapid reproduction, on the one hand, in bacterial metabolites and gut endotoxin inhibits the growth of other harmful flora, on the other hand, it formed the normal microbial flora in the host,Synthesize the main Vitamins for the host, provide nutrition and prevent the invasion of pathogenic bacteria.

Yak before 3 months of age: Because the rumen development and rumen microflora are still incomplete, the protein nutrition of calves is similar to that of monogastric livestock and poultry, and some essential Amino Acids cannot be synthesized in vivo. Therefore, when raising yaks before 3 months of age, a variety of protein feeds (such as bean cakes, cottonseed cakes, etc.) should be used in the feed. If the bean cake and the cottonseed cake are 1:1, it will be better for the calf's protein supplement feed than it is for the single feed bean cake, because the soybean cake contains more lysine and tryptophan and the methionine is lacking. By combining these two types of amino acids, amino acids can complement each other. If you add some feed containing more protein such as bran and alfalfa meal, the feeding effect will be better. During the growth process of yak, the body protein increases rapidly and the protein requirement is large. The younger the age, the greater the amount of protein needed, and the proportion of protein feed in the diet can account for 20%.
6 to 12 months old yaks: When the weight of 150-200 kg fattening, the content of protein feed in the diet can be reduced to about 15%. Later, with the increase in body weight of yak, the content of protein feed in the diet can also be gradually reduced to 12%.
With old-age cattle fattening: fattening old age cattle, dietary protein feed content, only 10%, but must feed corn, sorghum, sweet potato dry and other energy feed.
Fattening high-grade beef cattle: In the production of high-grade beef for strength fattening, the content of protein feed in the diet should be increased by 2% to 3% compared with ordinary cattle fattening.
During the feeding and fattening of beef cattle, the addition of protein feeds according to the above-mentioned ratios can avoid feed waste, and can also give full play to the role of feed and the production performance of beef cattle. Get the highest feed rewards and the best economic benefits.
