Superovulation and Embryo Transfer in Five Varieties of High-Quality Mutton Sheep
摘要
Abstract
For further improving the quality of superovulation and embryo transfer results of different varieties of donor sheep, four different superovulation programs (CIDR + FSH reduction, CIDR + FSH + PMSG, CIDR + FSH + PG, CIDR + FSH equivalent) were conducted on 17 donor sheep (Du Bo, white Suffolk, Black Suffolk, Texel, Merino), and 87 good body condition hybrid sheep were choosed as receptors for embryo transfer experiments. The results showed that: the average available embryos number of the first (CIDR + FSH reduction) and the second superovulation group (CIDR + FSH + PMSG)( 6.20 and 6.60 pieces) were significantly higher than that of the third (CIDR + FSH + PG) and the fourth superovulation group (CIDR + FSH equivalent) (P <0.05); the average available embryo number of White Suffolk, Texel, Dubo (7.67,6.20 and 6.25 pieces) were significantly higher than that of black Suffolk and Merino (P<0.05). 95 fresh embryos were got from all the donor sheep, and 51 pubescent were transplanted were receptor sheep, which were checked 3 months latter by B-ultrasound, the pregnancy rate was 74.5% and the lambing rate was 88.2%. In conclusion, CIDR + FSH + PMSG is the best combination for superovulation program of high-quality mutton sheep.关键词
