Economic losses due to clinical mastitis in Karan Fries (Holstein Crossbred) dairy cattle*

A study was conducted to evaluate the economic losses due to clinical mastitis in Karan Fries cows maintained at National Dairy Research Institute, Karnal. The overall economic losses due to clinical mastitis using price of medicine and milk losses during the period of 2006–08 were considered for estimating economic losses. The incidence of mastitis was found to be 0.40 in 485 lactations of Karan Fries cows during the period 2006–08. Total milk loss and expenditure were estimated as 9899.73 Kg and Rs. 94,381.90 in 343 cases of mastitis. The average milk loss and expenditure on medicines due to mastitis were estimated as 33.02 ± 5.39 Kg and Rs 283.51±24.94 per case, respectively. Significant influence of clinical mastitis on milk loss and treatment cost per case was observed for season and period. The milk losses and cost of treatment per case were highest (49.96±10.20 kg and Rs 390.47±47.21) in summer season.
