Abstract
This study was carried out to determine the prevalence of mastitis in lactating Dairy Cow at District Dairy Farms in Sylhet and UVH, at Jaintapur during the period of January 2016 to December 2016. Mastitis was most frequently seen in cross breed cows. In Jaintapur Upazilla, most of cows were indigenous, but there were many farmers rear cross breed cow for the purpose of selling milk in market. In Dairy Farm, all cows were cross breed. The overall prevalence was higher in crossbred cows than indigenous cows. The prevalence of mastitis was higher in advancing age and in lactation period. The cows were more prone to mastitis during 1st month of lactation. There was significant relationship between prevalence of mastitis and associated risk factors like general physical condition, herd size, frequency of dung removal, floor drainage quality and condition of floor. Reproductive diseases and periparturiant diseases showed higher incidence of mastitis in cows.The overall prevalence of mastitis at Jaintapur was 7.15%. The prevalence of mastitis of dairy cows in Jaintapur Upazilla was more in rainy season and less in winter season. The prevalence of mastitis was 3.47% in summer season, 11.52% in rainy season and 5% in winter season. The overall prevalence of mastitis at Dairy farm was 6.91%. The prevalence of mastitis in dairy farm was more in rainy season and less in summer season. The prevalence of mastitis was 4.97% in summer season; 16.53% in rainy season and 5.29% in winter season.
