Abstract
A total 930 outbreaks of Foot and Mouth Disease (FMD) were recorded in Bangladesh from 1988 to 1991. Number of FMD outbreaks was recorded highest in Rajshahi division (304) followed by Dhaka (272), Khulna (203) and Chittagong (151). During 1988 to 1991, FMD outbreaks reached in peak level in 1990 (540) followed by 1989 (209), 1988 (95) and 1991 (86). Outbreaks though occurred throughout the year were higher in premonsoon and winter seasons. Morbidity rate was found significantly higher (p<0.01) in cattle (35.5%) than buffaloes (23.3%) and sheep/goats (4.8%). Of the cattle, bull/bullock infected more (p<0.01) than cows and calves. Morbidity rate in different animals was observed significantly higher (p<0.01) in Rajshahi and Dhaka divisions than in Khulna and Chittagong. Mortality specially in calves was found at the rate of 50.9%. Loss in milk yield was found to be 66.6%. Disease period for a FMD affected cattle varied from 16 to 26 days (average 22.7 days). Loss of working days per working cattle ranged from 14 to 24 days (average 21.2 days) and the loss in draft energy per cattle was found to be 12.7 to 18.9 KW hour.
