Beef cattle have different needs for protein in different growth stages. Protein feeds are added. Beef cattle cannot absorb and digest, which not only results in feed wastage, but also increases the burden on the gastrointestinal tract of cattle and causes diseases. Meet the needs of beef cattle growth and development of protein, affect the fattening effect and beef quality. In production practice, the amount of protein feed can be determined according to the different growth stages of beef cattle.
The calf's rumen development and rumen microflora before 3 months of age before 3 months of age are still incomplete and some essential amino acids cannot be synthesized in vivo. Therefore, attention should be paid to the combination of various protein feeds (such as bean cakes, cottonseed cakes, etc.) in the feed. For example, the combination of bean cake and cottonseed cake can be used as a supplemental feed for yaks, which is better than single feed bean cake. Because the bean cake contains more lysine and tryptophan, and methionine is lacking, these two protein feeds are used together. Amino acids can complement each other. During the growth process of yaks, the protein requirement is very large. The younger the yak, the greater the amount of protein needed, and the proportion of protein feed in the diet can account for 20%.
When the beef cattle of 6-12 months of age weigh 150-200 kg, the proportion of protein feed in FAO can be reduced to about 15%. Later, as the weight of beef cattle increases, the proportion of protein feed in the diet can gradually drop to about 12%.
The shelf cows with a weight of about 300 kilograms are fattened in the cowshed. The proportion of protein feed in the diet can account for 13%. Later, as the body weight gradually increases, the proportion of protein feed in the diet is gradually reduced, and the proportion of protein feed to the end of the finishing period accounts for 10% of the diet.
The proportion of protein feed in aged cows' aging cows' diets only needs 10%, but they must feed corn, sorghum, sweet potato dry and other energy feeds.
These seeds are a complete source of protein, meaning that they provide all nine essential amino acids.
Amino acids are the building blocks for all proteins. The body cannot produce nine of these acids, so a person must absorb them through the diet.
Relatively few plant-based foods are complete sources of protein, making Hemp Seeds a valuable addition to a vegetarian or vegan diet.
Hemp seeds are especially rich in an amino acid called arginine, which has benefits for heart health.
