A CLINICAL REPORT ON Prevalence, Risk Factors of Clinical Mastitis and Efficiency of Different Treatment Regimens on Bovine Clinical Mastitis at Sirajgonj Sadar Upazila in Sirajgonj District.

Abstract

The study was conducted to measure the prevalence, identification of risk factors and efficiency of different treatment regimens for clinical mastitis in dairy cows at Sirajgonj sadar upazila in Sirajgonj district from 27th October to 30th December, 2011. Total 80 farms and households were selected and 502 cows were observed for measuring the prevalence and identification of risk factors. For determining the efficiency of treatment regimens 18 cows were treated and followed up. The overall prevalence was 7.77% and the prevalence was higher in crossbred cows (8.78%) than indigenous cows (5.37%). The prevalence of mastitis was higher in advancing age (12.9%) and in 5th lactation period (15.38%). The cows were more prone to mastitis during 1st month of lactation (12.99%) and higher quarter prevalence rate. There was significant relationship between prevalence of clinical 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 (32.46%) of mastitis in cows. From 66.67% to 80% of the mastitis cows recovered when the drug choice and route of administration was rationally done on the basis of severity of mastitis.
