促性腺激素和饲养管理方式对蒙古牛超数排卵效果的影响
Effects of Hormones and Management Method on Superovulation of Mongolian Cattle
摘要
Abstract
The purpose of this study was to explore the effects of different origin and dose of FSH,dif-ferent management method of donor cows on the quantity and quality of superovulation in Mongolian cat-tle.The trial was conducted by randomization,sixty-eight donor cattle were divided into two groups.One group had 28 cattle,were fed in captivity,of which 14 were injected with domestic FSH and other 14 were injected with Belgian FSH for superovulation.The total dose of injection was 455 IU/head.Another group selected 40 cattle,were grazing and injected with domestic FSH for superovulation,of which 19 received a total dose of 455 IU/head and 21 received a total dose of 490 IU/head.The results showed that the effective superovulation rate of Mongolian cattle after the domestic FSH injection was 92.9％,and the average num-ber of total embryos(10.57),available embryos(5.79),and grade A embryos(5.00)were significantly higher(P＜0.05)than the number of FSH produced in Belgium.The dosage of FSH injection and the fee-ding management method of donor cows had no significant effect on the superovulation effect of Mongolian cattle(P＞0.05),but the effective overovulation rate of house feeding was 19.2 percentage points higher than that of natural grazing.In conclusion,it can be seen that when considering of cost performance,strengthening feeding management and selecting an appropriate amount of domestic FSH can effectively re-place imported FSH,and the appropriately reducing FSH does not affect the overdischarge effect.关键词
