On the other hand, male calves were found more infected (70%) than female calves (30%). In relation to age,mortality was found 20% at below one month of age, 16.67% in one to three month of age and no mortality foundin over three month of age.60% navel infection were complicated with non-descriptive abscess formation, 25% infection were complicated with myiasis and15% infection was consequence with arthritis. Navel ill is one of the great culprits for the production of dairy calf, so appropriate preventive measure should be taken to control calf mortality in Bangladesh.
