摘要: 美国是世界肉牛业最发达的国家之一,其肉牛产业链较健全、组织化程度较高。美国的肉牛品种有100多个,但常用的只有10个左右,其中,安格斯牛占全关登记注册种牛的40%。美国有95%的肉牛进行本交,只有5%的肉牛开展人工授精;商品牛群充分利用杂交优势来提高经济利益。美国在肉牛育肥方式上特别是高能量饲料和高蛋白饲料的应用上是非常科学合理的。

Abstract: The United States is one of the world's most developed countries in beef cattle industry, possessing a relatively sound beef industry chain and a high organizational degree. There are more than 100 varieties of beef cattle, but only about 10 varieties are commonly used, among which Angus cattle accounts for 40% of American registered breeding cattle. In USA, 95% beef cattle are crossed themselves, and only 5% are carries out artificial insemination; commodity herds take full advantage of hybrid vigor to improve economic benefits. The beef cattle fattening way, especially the application of high energy feed and high protein feed is very scientific and reasonable in USA.
