Abstract:
Identification of risk factors and early diagnosis are the most important tools to control mastitis in dairy cows. In this study, California Mastitis Test (CMT) was performed to assess sub-clinical mastitis, and cows, udder and milk were examined for clinical mastitis. The incidence of occurrence of subclinical and clinical mastitis was calculated during summer, winter and thermo neutral seasons. A total of 165 (Sahiwal and KaranFries) cows taken from NDRI farm during early lactation. The incidence of occurrence of mastitis in Sahiwal was 45, 32 and 23% (subclinical) and 40, 27 and 33% (clinical) and 40, 33 and 27 percent (subclinical) and 41, 32, 27% (clinical) in KF cows during summer, thermoneutral and winter season respectively. Thus, highest incidence was found during summer thereby indicating that cows were more vulnerable to mastitis in summer.
