Serological Investigation on Infectious Pathogens in Abortion Cows of Large-scale Dairy Farms in Wuzhong of Ningxia
摘要
Abstract
An epidemiological survey on infectious factors causing abortion in dariy cows was carried out in the Wuzhong of Ningxia.All sera were tested for seroprevalences of infectious bovine rhinotracheitis(IBR),neosporia-sis,bovine viral diarrhea(BVD)and brucellosis that may cause abortion by the ELISA.The overall seroprevalence of IBR was 48.84%,the overall seroprevalence of neosporiasis was 30.23%,the overall seroprevalence of BVD was 19.77%,the overall seroprevalence of brucellosis was 24.42%.The seroprevalence rate of dairy cow farms was 100%.The statistic analysis showed that there was a significant difference (P<0.05)in abortion rates of different parities among that there was a extremly significant difference(P<0.01)in first parity compared with other pari-ties,but the abortion rates had no significant difference (P >0.05)between different pregnancy time.The results showed that different degrees of infections of IBRV,Neospora caninum,BVDV and Brucella exist in part of the dairy cow farms in Ningxia.关键词
