Effect of the Substitution the Fish Meal with Shrimp Head Waste Fermented in Diet on Broiler Performance

Abstract

The experiment aimed to investigate the effect of fish meal (FM) substitution with the shrimp head waste fermented (SHWF) in the diet on broiler performance. The SHWF is the shrimp waste fermented with Waretha inoculum containing Bacillus amyloliquefaciens bacteria. The materials used for this experiment were 100 day-old-chick (doc) Arbor Acres CP-707 strains unsexed. The experiment was arranged in Completely Randomized Design in five treatments and four replications with five chicks each. The broilers were randomly assigned in five different levels of SHWF as substitution of fish meal in the ration. The treatments were 0 % substitute (R0), 5 % FM substitute with SHWF (R1), 10 % FM substitute with SHWF (R2), 15 % FM substitute with SHWF (R3), and 20 % FM substitute with SHWF (R4) respectively. The result of this experiment indicated that feed consumption, weight gain, feed conversion ratio and body weight were not significantly (P > 0.05). However, the percentage of carcass and abdominal fat showed a significant effect (P <0.05). The conclusion of this experiment is that substitution FM with SHWF until 20% in broiler diet can maintain a performance broiler. In this treatment, were the consumption of 2428.28 grams/head, bodyweight gain 1330.07 g/head, feed conversion ratio of 1.82; body weight 1383.17 g, the percentage of carcasses was 73.86%, carcass fat was 2.67% and percentage of abdomen fat was 1.92 %.
