摘要 选取121例乏情母牛随机分成4组:A为对照组:31头乏情母牛,常规饲养不做任何处理;B为功能性精补料Ⅰ组:30头乏情母牛,给予含Ca、P较多的精补料;C为功能性精补料Ⅱ组:30头乏情母牛,给予含Fe、Zn较多的精补料;D为功能性精补料Ⅲ组:30头乏情母牛,给予含Ca、P、Fe、Zn较多的精补料。结果表明:A组发情率9.7%,B组发情率63.3%,C组发情率70.0%,D组发情率86.6%;A组受胎率3.2%,B组受胎率50.0%,C组受胎率56.7%,D组受胎率80.0%。微量元素对乏情母牛有催情及提高受胎率作用。 Non-estrus cows causing sterile is a perplexing problem in raising cattle.In the present study,121 cases of non-estrus cows were treated with promoting estrus feed:feed containing Ca and P more,feed containing Fe and Zn more,or feed containing Ca、P、Fe、Zn at the same time.The results showed that the estrus rate in the cows were 63.3%,70.0% 86.6%,respectively.The pregnancy rate in the cows were 50.0%,56.7% 80.0%,respectively.The present findings demonstrated that the trace elements increased not only the oestrus rate but also the pregnancy rate.
