Background and Objective: The study was conducted to evaluate three different feeding regimens on growth performance and body composition of Kampung Unggul Balitnak chickens (KUB) during the growing period.

Materials and Methods: One hundred and eighty day old chicks were sexed and fed a commercial crumble diet containing 23% Crude Protein (CP) and 3000 kcal Metabolizable Energy (ME)/kg until 3 days of age after which they were fed according to 17% CP and 3000 kcal ME/kg as Low Protein-Low Energy (LP-LE), 19% CP and 3100 kcal ME/kg as Medium Protein-Medium energy (MP-ME) and 21% CP and 3200 kcal ME/kg as High Protein-High Energy (HP-HE). Each feeding regime was designed with three replicates and having 10 birds per replicate.

Results: Increasing CP and energy levels in the diet did not improve body weight at 53 days of age, and body weight gain during the overall experimental period (4 to 53 d of age). Feed conversion ratio (FCR) was more efficient (p = 0.0416) in higher protein and energy diets than the lower protein and energy diets. Giblets and inedible parts were not affected by dietary treatments. Sex of KUB chicks had significant effects on feed intake, FCR, drumstick, giblet and leg.

Conclusions: LP-LE diet (17% and 3000 kcal ME/kg) was sufficient for females while MP-ME diet (19% CP and 3100 kcal ME/kg) was appropriate for the males.
