The bacteria in the rumen use urea to synthesize the bacterial protein, and its use effect is affected by many factors. First, in the diet supplemented with urea, there must be a certain amount of easily digestible carbohydrates. In the process of utilizing ammonia to synthesize bacterial proteins, rumen bacteria need to supply available energy at the same time, and their action is supplied by decomposition of carbohydrates. Experiments have shown that when using crude fiber as energy source in the diets of cattle and sheep, the urea field is very low (about 22%), and when an appropriate amount of crude fiber and a certain amount of starch are supplied, the area of ​​urea can be increased to More than 60%. Second, supplement urea diet should also contain a certain percentage of protein. Some amino acids, such as lysine and methionine, are essential nutrients for growth and reproduction in summer. Not only do they participate in the synthesis of bacterial proteins as a component, but they also have the effect of regulating bacterial metabolism, thereby promoting the use of urea by bacteria. These amino acids must be provided by the protein in the diet. In order to increase the utilization of urea, the protein level in the diet should be appropriate. Third, cobalt and sulfur have an effect on the use of urea nitrogen. Cobalt is a component of vitamin B12 that plays an important role in protein metabolism, and microorganisms in the rumen can use cobalt to synthesize microorganism B12. If the cobalt content in the diet is insufficient, the synthesis of vitamin B12 is slow, which will affect the use of nitrogenous substances in the diet. Sulfur is a raw material for sulfur-containing amino acids such as methionine and cystine in the composition of bacterial cells. To improve the utilization of urea. In addition, the supply of calcium, phosphorus, zinc, and other minerals necessary for rubber life activities should also be guaranteed.
