PREVALENCE AND SEVERITY OF SUB-CLINICAL MASTITIS IN LACTATING COWS: DETECTION BY SURF FIELD MASTITIS TEST

A total number of one hundred cow milk samples were examined in the present study for the Sub-clinical mastitis. In our study 44% milk samples were found positive for Surf Field Mastitis Test (SFMT). Quarter wise infection rate was found to be 18.5% and 31.5% in fore and hind-quarters respectively. According to the IDF criteria, 14.17, 18.33 and 8.35% quarters had subclinical, latent and non specific mastitis, respectively. Incidence of sub-clinical mastitis was assessed in dairy cows kept under different farm management conditions in two villages of Panipat district, Haryana. The prevalence of mastitis in cows were determined by examination of changes in the udder viz., swelling, redness and hardness of udder, changes in milk colour and reduction in quality of the milk. Further, pH testing of the milk and Surf Field Mastitis Test (SFMT) was done to confirm the subclinical mastitis.
