猪咬尾症发生的诱因及防治措施

摘要

在集约化、规模化养猪生产中猪咬尾现象频繁发生,损伤的猪尾部通常发生类肿胀、尾巴变短或者脱落,导致患病猪发育不良,猪群生长发育减缓,甚至死亡.当日粮营养水平低于饲养标准或者饲料配制不合理、生活环境单调、环境卫生条件差、猪群饲养密度过大、组群方式不合理、猪患有疥癣和虱子等体外寄生虫时,均可诱发猪咬尾症.根据实际情况可通过提供充足的营养、科学饲养管理、改善饲养环境、定期驱虫、仔猪断尾等措施加以预防.探讨猪咬尾症的发生原因及防治措施对提高猪的生产性能,全面提升生猪健康生产具有重要意义.%In intensive and large-scale pig farming,the phenomena of pig biting tail occurs frequently.Damaged tails usually suffer from swelling,becoming short or falling off.These lead to an adverse effect on body development,and pigs' slow growth,or even death.Nutrition,breeding environment,metabolism and management factors are important reasons for the phenomena of pig biting tails.Therefore,the exploration on reasons and prevention measures of pig biting tails will be of great importance in improving its production performance,and promoting the overall health of pigs.
