The weight of internal organs relative to the body weight were studied in broiler and layer chicken of the same age group. The average weights of heart, liver, pancreas and spleen were 8.84±0.30, 35.05±7.15, 4.35±0.74 and 2.26±1.34 grams respectively and these formed 0.42 ±0.04, 1.65±0.22, 0.21±0.04 and 0.105±0.054 per cent of body weight in broiler birds. In layer birds the average weights of heart, liver, pancreas and spleen were 1.52±0.05, 8.09±1.05, 1.24±0.13 and 0.451±0.080 grams respectively and these formed 0.60 ±0.06, 8.09±1.05, 0.49±0.04 and 0.177±0.030 per cent of body weight . There was a significant difference in per cent organ weights among broilers and layers indicating that the mean per cent organ weight of layer chicken is more than that of broiler chicken of the same age group.
