| 摘 要： | 尿素在反刍动物生产实践中的应用较为广泛,但直接饲喂尿素也存在一些弊端。尿素在瘤胃中降解过快,产生的氨无法被瘤胃中的微生物及时有效地利用而大量积累,容易引起氨中毒,限制了其应用范围。因此,尿素缓释技术及其产品近年来得到了广泛的研究与应用。本文主要综述了尿素常用的包被材料、缓释技术在反刍动物上的应用效果,以为缓释尿素在反刍动物生产中更好地运用提供参考。

| Abstract: | Urea is of great practical significance and is widely used in production. However,feeding urea directly also has some disadvantages. Urea degrades too quickly in the rumen,which is easy to cause ammonia poisoning and greatly limits its application. Therefore,urea sustained release technology has been greatly developed. In order to provide information of slow-release urea usage for ruminants practice, the coating materials,sustained release technology,application effect and prospect of urea in ruminants were reviewed in this paper. |
