| 中文摘要 | 193头健康、经产的黑白花奶牛分为3个组,用3种不同的方法进行同期发情处理和胚胎移植。第1组:注射1次Lutalyse;第2组:注射2次Lutalyse;第3组:注射Fertagyl-Lutalyse-Fertagyl。结果表明:第1组和第2组之间的同期发情胚胎移植率无显著差异(P>0.05),分别为26.5%(21/79)和27.0%(18/68);第3组的同期发情胚胎移植率为60.9%(28/46),显著高于第1组和第2组(P<0.05)。 |
| 英文摘要 | Estrus synchronization is an important technique in embryo transfer.Several methods have been used in cow synchronization.However,previous reports showed that the efficiency of synchronization would be different due to the situation of the recipients as well as other conditions.In the present study,the effect of GnRH on estrus synchronization of cow recipients in embryo transfer was determined,and compared with that of using PGF2α method.193 hostein cows reared in the Kunming farm were randomly divided into 3 groups.Group 1,recipients were administered once 25 mg PGF2α (5 mg/mL).Group 2,cows were injected PGF[2]α twice,with 11 day interval between two administration,25 mg/one injection.Group 3,cows were injected GnRH (86 μg) followed by injection of 25 mg PGF[2]α 7 days later and a second GnRH (86 μg) administration 16 days later.Results showed that in group 3 there were more transferable recipients (60.9%) for embryo transfer compared with that in group 1 (26.5%) and in group 2 (27.8%),respectively.It seems that interval injection of GnRH/PG/GnRH is a better method of estrous synchronization. |
