| Abstract: | Objective]To explore the effect of estrus synchronization and timed artificial insemination on the reproductive performance of beef cattle in Wenshan prefecture of Yunnan province,a practical program of simple extension suitable for the improvement of Southern beef cattle was established.Methods]Through the application of estrus synchronization and timed artificial insemination in beef cattle,the effects of the technology program in Guangnan,Yanshan and Funing counties,was compared in Wenshan Prefecture.Results]The results showed that the average estrus rate was 93.24%for the three counties and the average conception rate was 80.94%,showing better application effect.The body condition of cattle had a great influence on the estrus effect,so it was a common problem to improve the level of feeding and management for cattle.Conclusion]The technology program has a potential effect on improving the pregnancy rate of cows,which is worth popularizing in beef industry in South China. |
