摘要: 为了充分挖掘进口乳肉兼用牛—弗莱维赫的繁殖潜力,探寻在北京地区饲养的乳肉兼用牛超数排卵的可行性方案,实现快速建立核心群的目标。在春季(3月份)和秋季(9月份)对同一牛群进行两次超排处理,超排用药量主要依据其体重与营养状况,两次超排程序相同。实验结果如下:(1)春季的头均可用胚数和妊娠率分别为5.33±1.51枚、81.82%,秋季的头均可用胚数和妊娠率分别为6.00±1.83枚、69.57%,二者之间差异不显著(P>0.05)。(2)经产牛在春季(3月份)和秋季(9月份)头均可用胚数分别为6.50±2.21枚,5.33±0.58枚,二者之间差异不显著(P>0.05)。育成牛在春季(3月份)和秋季(9月份)头均可用胚胎数分别为5.75±1.26枚,4.50±2.38枚,二者之间差异不显著(P>0.05)。表明:该试验方案可用于北京地区不同胎次弗莱维赫牛的超数排卵,超排季节可选春季或秋季。

Abstract: To fully explore the reproductive potential of import dual-purpose cattle Fleckvieh, determine its feasible scheme of superovulation in Beijing and quickly establish a core group of Fleckvieh, two superovulation experiments were conducted in spring (Match) and autumn (September) respectively. The superovulation doses were based on cattles’weight and nutritional status, and the proceedings of the two experiments were the same. The results showed that the average number of available embryos per female (5.33± 1.51) and pregnancy rate (81.82%) in spring had no significant difference compared with those in autumn (6.00 ± 1.83, 69.57% ) (P >0.05). There were no significant difference on the average number of available embryos per multiparity between spring (6.50±2.21) and autumn (5.33±0.58) (P >0.05). And there were also no significant difference on the average number of available embryos per nulliparity between spring (5.75±1.26) and autumn (4.50 ± 2.38) (P >0.05). The results indicated that this scheme could be used to conduct superovulation of Fleckvieh at different parities both in spring and autumn in Beijing.
