Research on Synchronization of Estrus and Superovulation of the Nanyang Cattle
摘要
Abstract
To discourse the effect of different medicines and treatments on the synchronization of estrus and superovulation ,three methods of synchronization of estrus (single treatment with PG , double treatment with PG ,CIDR+PG) and two superovulation plans(PG+ FSH ,CIDR+ FSH+PG) were used with 270 ,300 ,330 mg FSH on the Nanyang cattle in this research ,respectively . The results showed that :The synchronization of estrus rate of the double treatment with PG group and the combination CIDR with PG group were higher than the single treatment with PG group by 38.26 and 35.30 percenge points ;There were no significant difference of the corpus lu-teum ,picking embryo and available embryos after Nanyang cattles were superovulated with PG +FSH method and CIDR+FSH+PG method ,respectively .The effect on the delivered female cattle was slightly better than the heifer ,but the difference was not significant ;The available embryos of the treatment with 300 mg FSH group was significant higher than the group of the 270 mg and 330 mg group in young cattle heifer ,and the treatment with 330 mg FSH group was significant higher than the group of the 270 mg and 300 mg group in delivered cattle .The research shows that the better plan of the Nanyang cattle estrus synchronizationembryo is CIDR +PG and double treatment with PG ,superovulation is PG + FSH and CIDR+ FSH+ PG ;The proper dose of the FSH for the delivered cattle is 330 mg ,300 mg for heifer .关键词
