通过到有关部门向有关警犬繁殖人员询问了解有关情况,查阅繁殖记录,对发生繁殖障碍的警犬进行观察检查等方法,调查了公安部南昌警犬基地2002年-2006年间5年来发生繁育障碍的情况。
5年来,南昌警犬基地年平均母犬在栏数为86头,共发情母犬600头次,有93头次发情异常,占发情总数的15.5%(93/600);统计了305头次配种数据,共有21头次的交配发生障碍,占6.9%(21/305);统计452胎次配种记录,共有88胎次犬发生假孕、不孕和流产,妊娠异常发生率为19.47%(88/452);统计了产仔数952头数据,共发生胎儿发育异常102头,占产仔数的10.71%(102/952);统计354胎产仔记录,发生分娩异常28胎,发生率为7.91%(28/354)。
经调研分析警犬繁殖障碍主要原因有:犬自体因素引起繁殖障碍;热应激对犬繁殖的危害;饲养管理不良;疾病因素和繁殖技术问题。
由于引起警犬繁殖障碍的原因各异,经过科学分析,提出了以下综合防制措施:一是作好种犬选育及选配工作。二是消除热应激,提高种犬繁殖能力。三是强化种犬科学管理。四是掌握母犬发情状态,适时配种。五是加强犬病防制。六是积极开展犬的繁殖技术的科研工作。
