摘　　要：试验口服促孕散处理产后奶牛,通过直肠检查卵巢变化、子宫形态的恢复情况及统计发情率和受胎率,再结合酶联免疫吸附法(ELISA)检测中药处理组奶牛血清中FSH、LH、E2和P4激素水平的动态变化,进一步验证了促孕散对子宫复旧期间内分泌的影响。结果显示:1处理组30、45 d发情率分别是75%、90%,60 d内的受胎率为65%;2处理组血清中:FSH含量在5 d开始有上升趋势,30 d达到峰值,相比对照组试验中同一时期FSH含量差异极显著(P<0.01);LH含量在15 d有上升趋势,20 d达到峰值,相比对照组试验中同一时期LH含量差异极显著(P<0.01),30 d与对照比较差异不显著(P>0.05);P4含量在20 d后开始上升,20 d的含量极显著高于对照组(P<0.01),25 d达到最大值,与对照组比较差异不显著(P>0.05);E2含量在20和30 d出现2个波峰,均极显著高于对照组(P<0.01)。由此得出:促孕散可以加强产后奶牛的内分泌水平,进而起到了加快生殖系统恢复的作用。To deal postpartum cows with fertility-promoting powder,the ovarian change and the weaning-estrous interval,statistics conception rate by uterus shape were examined through a rectal,combined with the concentration of follicle-stimulating hormone（ FSH）,luteinizing hormone（ LH）,progesterone（ P4） and estradiol（ E2） from the serum of postpartum dairy cows by enzyme-linked immunoassay（ ELISA）,and the therapeutic effects of fertility-promoting powder on the endocrine of uterine involution were validated further. The result showed that（ i）The synchronization rate of treatment group was 75 %,90 % in the 30 and 40 days,and the conception rate was 65 % within 60 days.（ ii）In serum,the FSH content of treatment group rise at the 5thday and peaked at the 30 thday,and the difference was extremely significant（ P〈0. 01） in the same period compared with the control; The LH content of treatment group rise at the 15 thday and peaked at the 20 thday,the difference was extremely significant（ P〈0. 01） in the same period compared with the control. but there was not significant at 30th（ P〉0. 05）. The P4 content of treatment group were on the rise at the 20 thday,had a extremely significant difference（ P〈0. 01） at the 20 thday compared with the control and peaked at the 25 thday when there was insignificant difference（ P〉0. 05） compared with the control. The E2 content of treatment group were maximized at the 20 thand 30thday and extremely significant difference（ P〈0. 01） at the same time compared with the control. It was concluded that fertility promoting powder could enhance the level of endocrine in postpartum dairy cows and thus accelerate the recovery of the function of the reproductive system.
