OPTIMIZING WHEAT BRAN UTILIZATION FOR POULTRY PRODUCTION THROUGH ENZYME SUPPLEMENTATION:1. BROILER CHICKEN

Abstract

A study on optimizing wheat bran (WB) utilization for broiler chicken production
through enzyme supplementation was carried out at Balai Penelitian Temak, Ciawi in
cooperation with PT. Indofood Sukses Makmur Tbk., Bogasari Flour Mills in year
2002-2003. The aim of this study was to estimate the optimal level of WB in broiler
chicken diets. This study used 225 day-old broiler chickens (doc) obtained from
commercial local broiler chicken breeding farm. The design of the experiment was
based on the completely randomized factorial experiment 3 x 3. Three levels of WB: 30, 40 and 50 % with three levels of enzyme supplementation: 0.00, 0.01 and 0,02% were tested. There were 9 treatment diets, 5 replicates and 5 doc in each replicate. Broiler chickens were fed pellet diets and drinking water ad lib. for 5 weeks and then sacrificed. The results indicate that the increasing level of WB up to 50% in the diet significantly (P<0.05) decreased feed intake and growth rate but had no effect on feed conversion ratio (FCR) of the broiler chicken. FCR of 5 weeks old chicken were ranging from 1.61-1.77 with the best value obtained when fed 30% WB supplemented with 0.02% enzyme. Increasing level of the enzyme in the diet improved growth rate and significantly (P<0.05) increased feed efficiency (6%). There was no interaction effect between WB and enzyme supplementation levels on the parameters measured. This study indicates that the optimal and economical level of WB to be included in broiler chickens diet was 30% with 0.02% enzyme supplementation.
