摘 要:为了摸清张掖市百万头肉牛基地犊牛腹泻发病情况,对全市肉牛犊牛腹泻发病情况开展了详细调查。调查表明:张掖市每年肉牛犊牛腹泻发病率为9.6%,死亡率达3.5%,其中3周龄以内的新生犊牛发病率和死亡率最高。发病原因主要是妊娠母牛饲养管理不当、初生犊牛饲养管理不良、条件性致病菌和牛病毒性腹泻病毒混合感染。通过采取综合防治措施,全市犊牛腹泻发病率由9.6%降至3.8%,病死率由3.5%降至1.6%,取得了显著防治效果。To figure out incidence of calf diarrhea among millions of beef cattle base in Zhangye base, We conducted a detailed investigation for morbidity of calf diarrhea throughout the whole city. Our results showed that the incidence of calf diarrhea was 9.6% as well as the death rate was 3.5 % each year in Zhan- gye. And, newborn calves within 3 weeks had the highest morbidity and death rate. The incidence was mainly caused by pregnancy cow breeding mismanagement, newborn calves breeding mismanagement and mixed infection of conditional pathogenic bacteria and bovine viral diarrhea virus. By taking integrated con- trol methods, the incidence of calf diarrhea reduced from 9.6 % to 3.8 %, and the death rate reduced from 3.5 % to 1.6 % among the whole city, which achieved significant success.
