The addition of urea to cattle is only applicable to the winter and spring seasons, which are dominated by poor quality feed such as wheat straw, dry corn stalks, and hay. It is not appropriate to feed urea during autumn season with grass and mature grass seeds. 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. When the crude protein content in the feed reaches more than 12%, the addition of urea has not increased the effect of weight gain, but has begun to affect the weight gain or apparent weight. During autumn season, 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 continued supply of urea during the autumn season will not only not achieve the desired results, but will also have the opposite effect. At the same time, it will also cause waste and increase the cost of feeding.
