不同种公牛精子受精能力的差异及影响因素

The Differences and Effects of Different Bulls in Semen Fertilization Ability

种公牛精液品质的优劣,与人工授精的妊娠率和体外受精胚胎的发育率密切相关。无论是体外受精技术还是人工授精技术,均要求种公牛的精子具有较好的受精能力。本文阐述了影响种公牛精液品质的因素以及不同种公牛精液体外受精和人工授精结果的差异,从而得出无论是常规精液还是性控精液,人工授精和体外受精的妊娠率都会因为种公牛的不同而有所差异,以此体现了选择一头高受精率种公牛的重要性。

The quality of Bulls was considered to be closely related to the pregnancy rate in artificial insemination （AI） and the embryo developmental rate： Both artificial insemination and in-vitro fertilization （IVF） were largely dependent on the high bull semen fertility. The paper expounds that many factors effect the quality of bull semen, and there are difference between the results of AI and IVF with different bulls semen. Whatever conventional semen or sexy semen used, the pregnancy rate in AI and IVF would be different due to the semen from different bulls. So it＇s important to choose a bull semen with high fertility.
