In the winter and spring seasons (especially in winter), cows often feed on roughage such as hay, corn stover, wheat straw, and wheat bran. During this period, it is especially good to feed the right amount of urea.
Because when feeding urea, there must be a certain amount of carbohydrate in the feed to supply the energy needed for the growth and reproduction of bacteria in the rumen. The amount of carbohydrates can directly affect the utilization of urea. Therefore, when feeding urea to cattle, feed more corn stalks, wheat straw, wheat bran, mountain grass and other roughage and carbohydrate feed such as corn, melon and sorghum, and reduce the amount of protein feed. The test proves that the crude protein content in the feed is below 10%. When the roughage such as straw and mountain grass accounts for the vast majority of the diet, the utilization rate of urea in the rumen is about 70%, and the effect on the weight gain of cattle is also quite obvious.
Feeding amount and feeding method: Each cow is fed with 25 g of urea per 100 kg of body weight per day. After water is dissolved, it is thoroughly mixed with chopped roughage and crushed corn, dried melon, sorghum, wheat bran and other concentrates. It can be fed later, and urea can also be fed to silage for feeding.
