| Abstract: | The epidemiology of cow subclinical mastitis was investigated for 11 month in the large-scale dairy farms and culture park in Ningxia.The results showed that incidence of subclinical mastitis was 52.74% in culture park and the average incidence of that was 44.13% in large scale dairy farms.197 strains bacteria were isolated and identified from the milk in which the somatic cell was above 500 thousands.Animal attack experiment showed that isolated bacteria had a certain pathogenicity. |
