Abstract
The research aims to summarize the diagnosis and treatment methods of sheep mastitis,with the goal of reducing the incidence and minimizing the economic losses of livestock farms.The study took all the ewes in the pens of a sheep farm in Xinjiang as the experimental subjects.Based on the clinical symptoms and the test results of the diagnostic reagent for mastitis,milk samples of the sick sheep were collected.Through enrichment,isolation and selective culture,etiological research was conducted,and drug sensitivity tests and molecular biological identification were carried out.The results showed that during the seasonal change in the farm,a large number of sheep mastitis infections and outbreaks occurred.Among the 174 ewes examined,102 were diagnosed with mastitis,with an incidence rate as high as 58.62%.Among them,the incidence rate of clinical mastitis was 13.22%(23/174),and that of latent mastitis was 45.40%(79/174).After isolation and culture,eight isolates suspected to be Staphylococcus aureus were obtained.The isolates showed sensitivity to penicillin,streptomycin,norfloxacin and compound sulfamethoxazole,and the homology with Staphylococcus aureus all exceeded 96.00%.Based on the results of the drug sensitivity test,the treatment plan was designed.Except for a few ewes and some lambs that died,most ewes improved significantly after treatment,and the cure rate was 95.10%(97/102).Studies have shown that mastitis in lactating ewes in this farm is mainly caused by Staphylococcus aureus.The combination of drug treatment and strengthened feeding management is effective in both the treatment and prevention of mastitis.关键词
