SHORT COMMUNICATION - RELATIONSHIP BETWEEN PREVALENCE OF MASTITIS IN CROSS BRED COWS AND FARM MANAGEMENT CONDITIONS IN LAHORE, PUNJAB.

The aim of study was to determine the relationship between widespread presence of clinical/sub-clinical mastitis and different conditions of farm management for Friesian x Sahiwal (FxS) crossbred cows in Lahore district of Punjab, Pakistan. A total of 107 FxS crossbred cows were selected from three dairy farms having different management conditions (A: Very good, B: Good and C: Poor). The data of clinical and sub-clinical mastitis was collected using the cardinal sign (inflammation of udder) and white side test. Overall incidence of mastitis was recorded 26.2% including 12.72, 13.63 and 16.66% at farms with very good, good and poor management conditions, respectively. However, sub-clinical mastitis was recorded 9.09, 13.63 and 16.66% at farms with very good, good and poor management conditions. Prevalence of mastitis was 7.71% Sub-clinical and 7% clinical in udder quarters. It was concluded that mastitis level has linear relation with management conditions of farms. [ABSTRACT FROM AUTHOR]
