摘  要:
为提高奶水牛繁殖率,通过应用CIDR+PG法和Gn RH+PG法对德宏州奶水牛实施了同期发情定时输精试验.结果表明:两种方法的同期发情率和受胎率分别为87.7%和69.4%、41.8%和30.6%,CIDR+PG法效果显著优于Gn RH+PG(P<0.05).该技术的示范应用将奶水牛年平均受胎率提高到65%,比前期提高14.5个百分点,产犊间隔也缩短180d.CIDR+PG处理方法更为理想,适于推广.

摘  要:
The objective of this paper was to increase reproduction rate of dairy buffalo in Dehong of Yunnan province, through two methods that were Tr.1: CIDR+PG and Tr.2: Gn RH+PG as implementing estrus synchronization and timing insemination experiment. The results showed that the estrus rates of Tr1 and Tr2 were 87.7% and 73.1% while the pregnancy rates were 41.8% and 21.37%, respectively, of which Tr1 was significantly higher than that of Tr2(P<0.05). The average pregnancy rate of dairy buffalo was annually 65%, increased by 14.5 percent points than before, and the calving interval was shortened 180 days to Tr1 method. Hence, Tr1: CIDR+PG method was an ideal method in practice for application.
