放牧条件下不同处理对西门塔尔牛超排效果的影响
Effect of Different Treatments on Superovulation of Simmental Cattle in Pasture
摘要
Abstract
In order to study the superovulation technology of Simmental cattle under grazing condition, three schemes (A:FSH+PG; B: FSH+PG+GnRH; C: FSH+PG+CIDR+ GnRH) with domestic and imported FSH respectively were performed. The results showed the number of available embryos of the three schemes were 3.43±2. 41, 5, 93±3. 54 and 7, 21±3. 19 respectively with the domestic FSH. The average number of available embryos in scheme B, C were higher than that of scheme A (P<0. 05) with domestic FSH. The average number of available embryos in scheme C was the highest among schmes A, B and C" then there was no significant differences between B and C (P>0. 05); the available embryos number of the three schemes were 4. 34±2. 71, 6. 76±3. 79 and 7. 79±4. 23 respectively with the imported FSH. The average number of available embryos in scheme C was the highest and there was no significant differences between B and C(P>0. 05) , however B and C were higher than scheme A (P<0. 05). There were no significant difference between the domestic FSH and imported FSH groups for the average number of available embryos. It was concluded that scheme C was the best among the whole three schemes, then scheme B, and the scheme A was the worst; There was no significant difference between the domestic FSH and imported FSH groups, however, considering the price of domestic FSH is much lower than imported FSH, the better choice is domestic FSH.关键词
