ABSTRACT
Merawang chicken is a native local chicken from Merawang District at Bangka Island, South Sumatera, with a special specification in uniform feather color of redbrown or gold, that is similar to the Rhode Island Red. The study was conducted to investigate the phenotype and genotype traits of growth of Merawang chicken. The chicken were produced from mating group of 5 males and 20 females, with the ratio of 1 male the 3 to 5 females respectively. All of 113 chickens (55 males and 58 females) were reared with different rations of 17.63% CP2628kcal/kg of ME (LP), and 20.92% CP3133 kcal/kg ME (HP) with protein , energy ratio of 1:150 respectively, the feeding treatments for morning (a.m) and evening (p.m) were (1) Low protein (LP) morning-(LP) evening(2) High protein (HP) morning-(HP) evening(3) (HP) morning-(LP) eveningand (4) (LP) morning-(HP) evening, respectively. The data of body-weight and feed consumption for 2 to 12 weeks of ages were collected . The data were analyzed by analysis of variance of nested design to obtain the component of variance and covariance. The variance components were used to estimate the heritability and genetic correlation of growth traits.
The results indicated that the effect of dietary treatment on the body-weight, gain-weight, feed consumption and feed conversion were significant (
