摘要 母猪是生猪养殖业发展的基础,其繁殖率的高低,直接影响新生仔猪的出生数量,成活率和后期养殖成本,直接关系养殖效益。母猪繁殖障碍类疾病近些年来频繁出现,变异株毒性不断增强,已经成为困扰我国养猪业的巨大难题。云南省镇沅县者东镇是当地仔猪生产大镇,据统计2018年末我镇生猪存栏5.5万头,出栏5.3万头,猪肉总产量达到了4186t。但我镇生猪规模养殖程度较低,主要以千家万户的散养为主。近年来,不断有养殖户反映所饲养的母猪难受孕,繁殖率降低,产死胎和木乃伊胎的比例不断增加,造成生产效益较低,养殖收益不理想。为此笔者走访者东镇者东村、新文村、马邓村、学堂村等40户农户,进行了专项调查,现将调查分析报告如下,供养殖同行参考。
