犏牛杂种优势研究进展

The research progress on heterosis in cattle-yak

犏牛是牦牛与黄牛的杂交后代,常年生活在高海拔地区,具有对低温、低氧等恶劣环境适应性强的优点。笔者从犏牛的生长发育、肉质性能及产奶性能等方面与其亲本进行比较,以期为科学认识、合理开发利用犏牛提供参考。

Cattle-yak is the hybrid of taurine bulls and yak cows live in high altitude, has sueeessfully adapted to the alpine hypoxia. This paper reviewed the heterosis in growth performance, meat quality and milk production of cattle-yak. To provide reference for promoting the innovation and development of cattle-yak.
