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.

Key words: slow-release urea, coating, ruminant
