The experiment was conducted to study the effect of blood meal in various proportions on performance of broilers. 250 days old chicks were reared on the five experimental rations up to 42 days of age. Tile chicks were randomly distributed into five groups of 50 birds each. The body weight of individual birds, daily feed offered, refused feed and feed consumption was calculated weekly. Randomly five birds from each group were taken and slaughtered for carcass weight and weight of internal organs (liver, heart and gizzard). Results revealed highly significant (P less than 0.01) difference among weight gain of chicks fed oil different experimental rations A, B, C, D and E were 1634.66g, 1866.55g, 1808.04g, 1792.07g and 1755.34g, respectively. Results revealed highly significant (P less than 0.01)) differences among total feed consumption of' chicks were 4031.19g, 3960.45 g, 4127.25 g, 4147.19g and 4149.49 g, respectively. The total feed conversion was 2.47, 2.12, 2.28, 2.31 and 2.36 respectively. Better-feed utilization was observed in chicks fed oil ration B as compared to the other rations. Dressing percentage of birds was 56.23%, 63,41%, 61.43%, 60.38% and 57.74% respectively. Non- significant difference in the internal organs, i.e., heart, liver and gizzard was observed in all groups. Result indicated that the birds fed on ration B (3% blood meal) were high significant (P less than 0.01) better in weight gain, feed consumption and per unit weight gain ratio as compared to the birds fed on rations A, C, D and E. The present result indicates that (3% blood meal) can he used in the broiler diet without any side effects.
