In the process of raising cattle (meat cattle, cattle), some farmers add urea to cattle throughout the year. This is not very scientific. Urea is indeed a good supplementary feed for cattle and can replace some protein feeds. However, the addition of urea to cattle is only suitable for the winter and spring seasons, which mainly include wheat straw, dry corn stalks, and hay, and it is not appropriate to feed urea in the summer and autumn seasons, where grass and mature grass seeds are dominant. why?
Because when using urea to feed cattle, the level of crude protein contained in the feed must not be too high. If the crude protein content is high, the rate of protein synthesis by urea decreases. Experiments have shown that when the crude protein content in feed is below 11%, the utilization rate of urea in the rumen is about 70%, and the effect on raising the weight of cattle is quite obvious (increases 39%); when the crude protein content in feed reaches 12% In the above, the addition of urea did not increase the effect of weight gain, but began to affect weight gain or significant weight loss. In mid-summer and golden autumn, cows often feed on the seeds of plants and plants. In these feeds, the nutrients contained are relatively comprehensive, especially the crude protein content is high, generally 12% to 20%. Therefore, the summer and autumn season Continue to add urea, will play the opposite effect. At the same time, it will also cause waste and increase the cost of feeding.
