Effect of Diverse Factors on the Frequency of Clinical and Subclinical Mastitis in Kundhi Buffaloes of Sindh, Pakistan

The present study was aimed at determining the effects of diverse factors associated with clinical and subclinical mastitis in buffaloes. Significantly higher prevalence (49. 07%) of clinical mastitis was observed in buffaloes with average age of 6 to 9 years whereas those of > 9 years of age showed higher (33.33%) but non-significant prevalence of subclinical mastitis. However, significant impact of the number of parity on the prevalence of clinical mastitis was observed in animals. Higher prevalence (48.20%) of clinical mastitis was observed in buffaloes with 4 to 7 calves. A similar trend of significant influence of the number of parity on the prevalence (39.72%) of subclinical mastitis was also noted in animals given more than 7 parity. Significant role of the humid hot summer month (August) on the occurrence of apparent and non-apparent mastitis in buffaloes was determined. The soil bedding material played significant role in the prevalence of both, clinical and subclinical mastitis. Significantly higher prevalence of clinical mastitis was observed in August (52, 10.74%), while the overall prevalence (26.65%) was determined during hot humid summer season. Similarly significantly higher frequency of non-apparent udder infection in animals was documented during August (36, 10.90%). The overall higher mean incidence (31.81%) of subclinical mastitis was detected in hot humid summer.
