Data of 6 batches of layers, 44 batches of broilers and 5 batches of Girirani spread over a period of 3 years was utilised for the study. Birds were maintained in a standard managemental condition. Dead birds were subjected to thorough post morteum examination. Mortality was higher in rainy season both in layers and Girirani, which was 76.78% and 63.59% respectively, followed by summer season 15.24% and least in winter season in layer. In case of broiler maximum mortality was seen in winter season 54.17% followed by other seasons. Maximum deaths of the bird were due to enteritis (33.02%), pneumonia (26.06%), week hatch (18.10%), Ascitis (9.60%) followed by coccidiosis, inanition, pulmonary oedema, etc. in broilers. Whereas in case of layers deaths due to cannibalisms and coccidiosis (35.87%) was highest followed by enteritis (12.65%) and pneunomia (9.92%). Other incidences like egg peritonitis (8.98%), internal parasites, ascites, coccidiosis etc., were also recorded. In Girirani birds 44.70% death was recorded due to coccidiosis, 15.67% cases of enteritis, 13.82% of pneumonia and 8.76% cases of weak hatch. Other cases like pulmonary oedema (5.07%) cannabalism (2.76%) and omphalitis (2.30%) were also observed. Proper managemental care in rainy and summer season may prevent the causative agents. Due care to be taken to control enteritis, pneumonia and Ascites.
