摘要
母牦牛繁殖障碍综合症是玛曲县托牛业的重要疾病之一,以流产,死胎、难产、弱犊和不育为其主要特征,据15个自然放牧点的49个牛群2—5年(1—5个产犊期)调查结果证明,在1929头次生产母牛中,有繁殖障碍综合症牛205头次(占10.63%),其中流产101头次(49.27%),死胎24头次(11.71%),难产34头次(16.59%),弱犊31头次(15.12%),不育15头次(7.32%);在生产的1929头次母牛中,空怀母牛739头次(38.31%));产犊985头,发病136头(13.81%。生产母牦牛繁殖障碍综合症的发生无明显的品种、胎次和季节性差异,常使牦牛业蒙受较大的经济损失;因此,应加强对牦牛繁殖综合症的诊断和防治研究。
