和牛杂交牛高强度重复超排效果的研究
Studies on Effects of High-intensity and Repeated Superovulation in Wagyu-catalo
摘要
Abstract
To study the repeated superovulation effect in brief period in wagyu-catalo,100 head of wagyu-catalo were super-ovulated continuously for three times from Jun in 2011 to Aug in 2011. The three times superovulation obtained the mean of embryo recovered were 11. 65±8. 96,13. 28±7. 69 and 13. 24±8. 39,respectively;the mean of usable embryos were 7. 52± 7. 16,8. 51±6. 94 and 8. 92±6. 59,respectively. The experimental results indicated that a good result could be obtained by proceeding consecutively three times repeated superovulation in 33 d interval in wagyu-catalo. There were obvious individual differences in the effect of superovulation. The superovulation efficiency of primiparous was a little better than multipara cow (P>0. 05) ,but the number of available embryos of multiparous was better than primiparous cow notablely(P<0. 05),关键词
