| Abstract: | 22 heads black -white Dariy cows were Superovulated with reagent, medication and instrument made in China, and effective superovulation was 72. 7%(16/22). We collected 143 embryoes among which the embryoes fitting transplant was 70%. Superovulated cows had average 6. 5 embryoes in which 4. 5 embryoes were fitting transplant. These were average 8. 9 embryoes and 6. 3 embryoes fitting transplant according to cows collected embryo. After frozen-thawing, the practicable embrryoes were 68. 2%(30/44). 18 heads synchronous estrus Yellow cow recipients were transplanted the embryo, among the recipients 3 heads were pregnancy and 2 heads pregnantting twins were miscarriage at six month. 1 head has borne a black-white bull calf. |
