浅谈影响种公猪繁殖性能的因素

A brief discussion on factors affecting breeding performance of breeding boars

随着我国经济产业结构调整,养猪业向集约化、专业化和工厂化的现代养猪生产模式发展,人工授精技术在养猪业得到广泛应用。文章对影响种公猪繁殖率的因素进行综合性阐述,指出猪的品种、健康状况、饲养管理技术、饲养环境条件及人工授精技术等均会影响种猪的繁殖性能。高温季节避免种猪发生热应激反应,良好的饲养管理技术可提高种公猪的免疫力,改善精液品质;防止精液在保存期间发生氧化应激反应,延长精子的存活时间;使种猪处于最佳生产状态,保证其生育能力,提高种猪的繁殖性能,促进养猪业的健康发展。

Along with the adjustment of economy and industry structure,the pig industry has developed into the modern model of intensive,specialized and industrial pig production.Artificial insemination technology has been widely applied in pig industry.The paper comprehensively expounds the factors that affect the reproductive rate of breeding boars.It is pointed out that the breed,health condition,breeding management technique,breeding environment condition and artificial insemination technique of pigs all affect the reproductive performance of breeding boars.Heat stress reaction of breeding pigs can be avoided in high temperature season.Good breeding management techniques can improve the immunity of breeding boars,improve semen quality,prevent oxidative stress reaction of semen during storage,prolong the survival time of sperm,make breeding pigs in the best production state,ensure their fertility,improve the reproductive performance of breeding pigs,and promote the healthy development of pig breeding industry.
