Abstract
Phenotypic characteristics are essential in creature hereditary asset protection and improvement. Phenotypic characteristics of 152 female and 52 male Indonesian Chicken gathered from five populations (Kedu, Gaga, Merawang, Nunukan, and Pelung) were collected. The quantitative traits data, including body weight (BW) and body size measurement, consists of 11 variables, such as beak length (BL1), wattle length (WL1), breast width (BWI), breast circumference (BC), wing length (WL2), breast length (BL2), femur length (FL), tibia length (TL), shank length (SL), shank diameter (SD), and third finger length (TFL) were measured and analyzed using analysis of variance to test the effect of different breed populations. As a result, the male and female Pelung chicken has a higher value in all characteristics, except for WL1 in female Pelung, compared to other breeds. For the BL1 and TL traits, both male and female Kedu chicken has the lowest value. All observed quantitative variables were higher in male compare to female chickens. In conclusion, Indonesian local chicken phenotypic differences provide the potential for future genetic improvement within the breed populations and could be used for designing breeding programs and selection.
