Plumage colours Stability in Inbreed Pelung Chicken

Pelung is one of the most importance local chicken in Indonesia. Genetic introgression and inbreeding depression were the major threat for local chicken gene pool. The objective of this research was to investigate the effect of serial inbreeding mating to plumage colours of Pelung chicken. Pure Pelung chicken which purchased from Cianjur sub-district was undergo full-sib mating through five generation. All offspring phenotypes was recorded. The results show gradual plumage phenotype change of inbreed Pelung chicken. Initially, adult male chicken had Black-red coloured as wildtype (WT) shifted to partridge and black-silver coloured in later generations. The current findings indicating that inbreeding made recessive traits to be expressed which some of them might had deleterious effect. Random mating should be maintained to preserve genetics stability of Pelung chicke
