摘要:母牛不孕症主要表现2种,一种是在母牛正常发情期内没有发情,从而无法受孕;另一种是在母牛发情且参与配种的情况下,难以成功受孕。不孕症是母牛飼养过程中常见的繁殖性障碍疾病,导致母牛不孕的原因有很多,主要包括营养不良性不孕、疾病性不孕、先天性不孕、体质性不孕及繁殖技术性不孕等。该文主要论述几种母牛不孕症发病原因及防治。

0引言
我国对牛类产品的需求量与日俱增。而母牛不孕症的出现严重阻碍牛数量的增长。为改变这一现状,需要重点围绕着母牛不孕症进行全方面、多角度地分析和研究,并对母牛的情况进行认真观察和细致了解,同时,结合新疆阿勒泰地区福海县的母牛饲养现状,进行科学、合理地防治,由此促进区域母牛产量的增加和养殖行业的长远发展。
1营养不良性不孕
母牛出现营养不良的原因有2点,一是喂养饲料的质量问题;二是母牛的饲养管理问题。其中,最重要的是饲料问题[1]。营养不良性不孕的母牛大多数饲喂的是粗饲料,其中干草居多,还有部分枯黄的玉米秸秆,长时间饲喂这样的草料,会导致母牛严重营养不良,最终致其不孕。不良草料中的营养匮乏,正常饲喂的饲料应该适当添加玉米、豆粕等精饲料。管理不善,主要指饲养人员未给母牛提供舒适的生活环境,母牛冬季受到寒冷冰冻的侵害,夏季又因为长时间风吹日晒,及运动不足,或平时的劳动量过大等,这些情况都有可能造成母牛不孕。……
