Gradient Replacement of Fish Meal with Poultry By-Products Meal in Broiler Rations Supplemented by Amino Acid

Abstract

4 Abstract: The present study was conducted to evaluate the effect of different levels of poultry byproducts meal (PBM) on the performance of broiler chicks. One hundred and fifty day old (male and female mixed) Hubbard broiler chicks were reared on the five experimental rations up to 42 days of age using control rations containing 8% fish meal. In the experimental rations both in starter and finisher fish meal was replaced by the poultry byproducts meal (PBM) at 2, 4, 6 and 8% levels keeping control rations without PBM. The starter rations were fed up to 28 days of age and remaining 14 days the finisher rations were fed. The crude protein (%) and metabolized energy (Kcal/Kg) content of the starter rations A, B, C, D and E were 21.52, 2937; 21.71, 2916; 21.89, 2983; 22.0, 83007 and 22.29, 3032, respectively, while for finisher rations were 18.73, 3042; 18.92, 3070; 19.10, 3097; 19.29, 3125 and 19.47, 3152.28, respectively. The result showed that the rations containing PBM at the level of 2, 4 and 6% were the best for growth as compared to 8% consumed. There was a non-significant (p<0.05) difference in feed efficiency among different rations. The varying level of PBM used in rations did not significantly (p<0.05) influence the dressing percentage of broiler chicks. It was also concluded that PBM can be used in broiler rations up to 8% of the total diet. It is concluded that PBM supplemented with amino acids may be suggested to be suitable and replace with fish meal in poultry diet.
