摘要
为了解金川牦牛群的繁殖情况,试验对2011—2015年金川县毛日乡热它村金川能繁母牦牛5 419头(15肋骨母牦牛3 746头,14肋骨母牦牛1 673头)进行调研。结果表明:15肋骨母牦牛平均繁殖率、成活率和繁殖成活率分别达到86.00%、61.93%、52.50%,分别比14肋骨母牦牛的高8.48,4.31,8.22个百分点;金川母牦牛平均繁殖率、成活率和繁殖成活率最高分别为87.72%、72.77%、50.80%,最低分别为64.75%、53.90%、46.15%。
In order to understand the reproductive performance of Jinehuan yak ,5 419 multipara yaks（ containing 3 746 multipara yaks of 15 - pair ribs and 1 673 multipara yaks of 14 -pair ribs）were investigated in the present study from 2011 to 2015 in Reta village of Maori township of Jinchuan county. The results showed that the mean values of reproductive rate ,survival rate and reproductive survival rate of muhipara 15 - pair - rib yaks were 86.00% ,61.93% and 52.50% respectively,with 8.48% ,4.31% and 8.22% each higher than those of 14 - pair - rib yaks. The highest mean values of reproductive rate,survival rate and reproductive survival rate of Jinchaun yaks were 87.72% ,72.77% and 50.80% respectively during the five years,meanwhile the lowest were 64.75% ,53.90% and 46.15%.
