摘要
本文对影响公牛精液品质的因素进行了分析,并提出改进措施。影响因素主要有公牛的营养(蛋白、维生素、矿物质与微量元素)、饲养环境(夏季高温的应激影响)、年龄、采精技术、遗传(睾丸发育与遗传因素)与自身免疫的繁殖障碍等。
The main influencing factors in the quality of bull semen were analyzed in this study. The improvement measures were proposed. The influencing factors are as follows： the nutrients of bulls（protein,vitamins, minerals, trace elements）, the feeding environment（the influence of heat stress）, age, the technology of semen collection, the genetic（testicular development and genetic factors）and the immunological reaction of bulls.
