Pengaruh Lama Periode Brooding Dan Level Protein Ransum Fase Starter Terhadap Produksi Karkas Ayam Kedu Hitam Umur 10 Minggu (Effect of Brooding Period and Diet Protein Level of Phase Starter on the Carcass Production of Black Kedu Chicken 10 Weeks Age

The present study was conducted to determined the effect of brooding period with different diet protein of phase starter on the carcass production of black kedu chicken age 10 weeks. The material used was 108 day old chick (DOC) black kedu chicken (unsex) with an average weight of 38.52 + 3.28 gram (CV = 4.70). Feed used in the formulation of diet is corn, rice bran, soybean meal and fish meal. The experimental diet containing metabolism energy 2800 Kcal/kg and crude protein 18%, 20%, 22% according to treatment and finisher diet with crude protein 16%. The experimental design used was split plot. Brooding period (B) as the main plot consists of B1: 1 week brooding period, B2: 2 week brooding period, B3: 3 week brooding period and protein levels (P) as the subplot consists of P1: 18%, P2: 20% and P3: 22%. The basic design used was completely randomized design consisting of three replicates and each unit consists of 4 individuals. The results showed that there was no interaction effect between brooding period and diet protein levels on carcass production. The treatment of brooding period showed no apparent effect on the production of carcass, but the treatment of diet protein levels showed a real influence results. The increasing protein level of diet will improve also live weight, carcass weight and carcass percentage of black kedu chicken age 10 weeks
