Improvement of Nutritional Quality of Processed Palm Kernel Meal with Protease Enzyme as a Substitution for Rice Bran on Broiler Performance

Abstract

Rice Bran is the most basic and common raw material used in broiler feed, but its replacement with proceed palm kernel meal (palmofeed) adding with enzyme protease is not clearly evaluated. This study was conducted to evaluate the improvement of nutritional quality of proceed palm kernel meal with protease enzyme as a substitution for rice bran. Rice bran 7.85% and feed reformulation of proceed palm kernel meal with protease enzyme 7.85% on broiler performance and IOFC. A total 120 female broilers DOC CP 707 were randomly allocated into 2 treatments with 6 replicates and 10 birds per pen. Treatments were a control (T0) using standard diet nutrient requirement with 7.85% rice bran, treatment (T1) with feed reformulation of proceed palm kernel meal with protease enzyme 7.85%. The diets were fed in two phases as pre-starter (day 1-7) and grower to finisher (day 8-35). Compared to T0, the result showed that replacement rice bran 7.85% by feed reformulation of proceed palm kernel meal with protease enzyme 7.85% were not significantly (P<0.05) increase body weight (2194 and 2199) or weight gain (2151 and 2155), lower FCR (1.844 and 1.814) or mortality-corrected feed conversion ratio (mFCR) (1.326 and 1.375), performance index/PI (474 and 457) and IOFC (850, 491 and 922, 738). These data showed substitution of rice bran with processed palm kernel meal with enzyme protease does not has a negative impact on performance and is proven to be profitable from the point of view of IOFC business analysis.
