Yak fattening calves before 3 months of age have a faster growth rate and a large amount of protein. In the diet, protein feed can account for 20%. At the same time, because the rumen development is very imperfect, the body can not synthesize some essential amino acids, so it should be fed with different protein feed. When the yak is 6-12 months old and weighs 150-200 kg, the protein feed in the diet can be reduced to about 15%. Later, as the weight of the calf increases, the amount of protein feed in the diet can be gradually reduced to 12%. Shelf cattle fattening in the house for fattening, shelf weight of about 300 kg of shelf cattle, protein feed in the proportion of its diet can account for 10% -13%. By the end of fattening, the protein feed can account for 10% of the diet. Older cattle fattening is fattened by older cattle. The protein feed in the diet needs only 10%, but it must be fed with energy feed such as corn, sorghum and sweet potato. If fattening high-grade beef cattle is to be fattened with high-quality cattle to produce high-grade beef, the content of protein feed in the diet should be increased by 2%-3% compared with ordinary beef fattening.
