导入美国瑞士褐牛血液对提高新疆褐牛生产性能的效果

Effect on Production Performance of Xinjiang Brown Cattle by Inducing American-Switzerland Brwon Cattle Blood

[目的]为了提高新疆褐牛的生产性能。[方法]通过导入美国瑞士褐牛血液的方式,并对F1生长发育和生产性能等指标进行了测定。[结果]表明:美新褐牛F1在保持新疆褐牛适应性强、放牧性能好的基础上,产肉和产奶性能均有所提高,体高和体长的增加较为显著,体格高大,体形修长,体型结构趋于合理;毛色变浅褐色,趋于一致。[结论]说明新疆褐牛通过导入外血是提高生产性能的有效途径之一。

【Objective】It was to improve the production performance of Xinjiang Brown cattle.【Method】The indexes of growth and development and production performance were detected of F1 generation which was produced by introducing American-Switzerland brown cattle.【Result】The results showed that performance of beef and milk production of F1 increased based on remaining good adaptable and grazing performance of Xinjiang brown cattle.The body height and size of F1 increased significantly.The hybrid was physical tall and has slender body,the body structure was more reasonable,the hair was light brown.【Conclusion】It indicated that introducing foreign blood was one of the most effective method to improve the production performance.
