ABSTRACT
Objective: To evaluate the biological performance of broilers as affected by partial and total replacement of spent dried salted fish to Peruvian fish meal in the ration. Specifically, to determine the effects of diets on feed intake, average daily gain, feed conversion efficiency, gain in weight, dressing percentage, liver weight, cost per kilogram of meat produced and income over feed and chick cost of broilers.
Materials and Methods. The feeding trial was conducted for 40 days at the Poultry Project of BPSU Abucay Campus from June 18 – July 28, 2009. A total of 150 straight- run day-old Cobb Vantress strain were used in the study. They were randomly distributed to three treatments following a completely randomized design, with each treatment replicated five times with 10 birds per replicate. The treatments were: basal diet as control (T1), 50% Peruvian fish meal + 50% Spent dried salted fish (T2), 100% Spent dried salted fish (T3). Birds were fed with treated diets at starter and finisher stage. Sample of spent dried salted fish was subjected to laboratory analysis to determine nutrient values such as; Crude Protein (CP), Fat, Moisture, Calcium, Phosphorus and Salt. The data was subjected to analysis of variance using DMRT to determine the significant differences among treatment means.
Results: Broiler rations with partial and total replacement of spent dried salted fish to Peruvian fish meal did not show significant difference (P>0.05) on broilers biological performance, specifically on average live weight gain, average daily gain, feed conversion ratio, dressing percentage, and economic efficiency of the birds, except for feed consumption at finisher stage in which birds at T3 showed a significantly higher (P<0.05) feed consumption. Generally, despite of lack of significant differences among treatment mean values of treated diets, the birds fed with ration of 100% spent dried salted fish gave the highest average daily gain, average live weight gain, dressing percentage and marked the least cost to produce a kilogram of broiler that gave the highest income over feed and chick cost. The result indicates that spent dried salted fish can be used and considered an economic and viable alternative to fish meal as source of protein in broiler ration. Considering the comparable effects of the ingredient with Peruvian fish meal on biological and economic parameters used in the study, therefore spent dried salted fish is a potential local source of protein ingredient for broiler feeds.
Conclusion. With broilers comparable biological and economic performance on rations as affected by partial and total replacement of spent dried salted fish to Peruvian fish meal can be explored as alternative source of animal protein in broiler ration.
Key words: spent dried salted fish, Peruvian fish meal, local fish ingredient
