PERFORMANCE AND PROTEIN EFFICIENCY OF BROILER CHICKEN FED “ON COM” OF TAFU BY-PRODUCT

Abstract

The research was conducted at Poultry Production Laboratory, Faculty of Animal
Husbandry, Diponegoro University Semarang. The aimed of this research was to
investigate the effect of “oncom” of tofu by product (OTBP) on the diet to performance and protein efficiency of broiler chicken. One hundred broiler chicks unsex, one week old with initial body weight l18,45i12,34g were used in this experiment. The chicks were reared on the litter house system. They were divided into 20 pen (100 x 75 x 60 cm), and each pen contained 5 chicks. The bird were fed diet consisted of yellow corn, rice polish, fish mill, mineral and vitamin mix and OTBP. The diets for starter and grower are 22 and 20% CP and 2.900 and 3.000 kcal/kg diet. The experimental design was completed randomized design (CRD) with 4 treatments and 5 replications each. The treatments were: diet with 0% OTBP (TO); diet with 10% (T1) OTBP; diet with 15% OTBP (T2); diet with 20% OTBP (T3). The result showed that average feed consumption of T0, Tl, T2 and T3 were 2.201; 2.095; 2.100 and 2.104g respectively. Average body weight gain it is 896; 963; 984 and 1.038 g for T0, Tl, T2 and T3 respectively. Average feed conversion of T0, Tl, T2 and T3 are 2,21; 2,18; 2,14 and 2,03 respectively. Average carcass weight are 651; 668, 704 and 746 g for T0, T1, T2 and T3 respectively. Average carcass percentage of T0, T1, T2 and T3 were 62,06, 63,44; 63,86 and 66,13 % respectively. The average protein efficiency is 2,17; 2,20; 2,18 and 2,40 for T0; Tl; T2 and T3 respectively. It can be concluded that “oncon” of at level 20% can be used in the diet for good performance and efficient of broiler chicken.
