Fattening cattle to feed protein feed

During the fattening process of beef cattle, the amount of protein feed should be appropriate. Different beef cattle have different protein requirements at different times. Feed more protein, feed, beef cattle can not absorb, resulting in feed waste, increase feed costs; but also give the gastrointestinal gastrointestinal burden increase, causing disease; protein feed fed less, can not meet the needs of beef cattle growth and development of protein, will be direct Affect fattening effect. Therefore, the feeding of protein feeds to fattening beef cattle will vary from time to time due to cattle. Yak Fattening: Yaks before 3 months of age have a fast growth rate and need a lot of protein. In the diet, the protein feed content can account for 20%. At the same time, due to its imperfect rumen development, the body can not synthesize certain essential amino acids, so it is suitable for feeding different protein feeds. When calves grow to 6 months to 12 months and weigh 150kg to 200kg, the protein feed content 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%. Shelf fattening cattle: In the cowhouse with fattening, shelf weight of about 300 kilograms of cattle, the proportion of protein feed in the diet, can account for 10% -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. 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. In addition, if high-quality beef is used for fattening and producing high-grade beef, the protein feed content in the diet should be increased by 2% to 0.03% compared with ordinary beef fattening.
