STUDY ON MORBIDITY AND MORTALITY RATE AND THEIR PROBABLE CAUSES OF BLACK BENGAL GOATS AT SADOR UPAZILA OF SIRAJGANJ, BANGLADESH

The experiment was conducted to investigate the morbidity and mortality rate of Black Bengal goats under quarantine farm (QF) condition and their probable causes from July 2013 to March 2014 at 8 villages of Sador upazila of Sirajganj district in Bangladesh. The necessary data were collected from 1152 goats of 12 quarantine farm. Then it was found that average morbidity and mortality rate of goats at study area was 12.5% and 6.1% respectively. Maximum mortality of adult goat was due to enterotoxaemia (50.0%) followed by diarrhoea (16.1%) and pneumonia (14.3%) and maximum mortality of growing goats occurred due to pneumonia (35.7%) followed by diarrhoea (28.6%). There was a seasonal variation of adult mortality. Maximum adult mortality occurred in cold and dry period (66.1%) than hot and wet period (33.9%). Adult goats died mostly due to enterotoxaemia (54.1%) in dry season when there were shortages of green grasses in the grazing lands. Overall incidence of diarrhoea of adult goats ranked in top (31.9%) that was followed by pneumonia (14.3%), conjunctivitis (12.6%) and ecthyma (10.9%).
