Effects of Different Treatments on Estrus Synchronization in Dairy Goats
摘要
Abstract
[Objective]In order to establish a technical scheme suitable for estrus synchronization of dairy goats.[Method]This experiment explored the effect of estrus synchronization of dairy goats through different progesterone suppositories and hormone types,different treatment schemes,different seasons and different parities.[Results]That the PRID was placed on the 0th day,14:00;on the 9th day,PMSG 330 IU was injected intramuscularly at 14:00.On the 11th day,the thrombus was removed at 14:00,and PG 0.2 mg was injected intramuscularly.On the 12th day,the estrus synchronization procedure of 20:00 was performed on the first and second parity ewes in the natural estrus season of dairy goats(October-February of the next year).The estrus rate can reach more than 81％,and the cost is relatively low,which is suitable for large-scale dairy goat farms in Inner Mongolia.[Conclusion]Therefore,we can carry out the estrussynchronous in large-scale dairy goats farms in Inner Mongolia by this scheme,which is easy to operate,cost-effective,and can achieve a high estrus rate.关键词
