Morphometrics and Heritability of the Body Of 1-8 Weeks Aged Tolaki Chickens

Efforts to identify and characterize local chicken breeds are still considered important because, in addition to being useful for the collection of Indonesia's genetic resources, they also support Abstract | The Tolaki chicken is a native breed from Southeast Sulawesi, commonly found in areas such as Konawe Regency and South Konawe Regency.This study aims to provide insights into the estimated heritability value of the body weight of Tolaki chickens aged 1-8 weeks.The mating group consisted of 5 males and 25 females, with each male paired with 5 females, resulting in the production of 150 Tolaki chicks.The chickens were fed ad libitum.Data from the research were analyzed using a Complete Randomized Design (CRD) with an analysis of variance and a nested design pattern (hierarchical structure) to calculate the variance components.These components were then used to estimate the heritability value of the Tolaki chickens.The findings revealed that the inheritance of traits (heritability) for Tolaki chickens, based on the male component (ĥ 2 s), the parent variation component (ĥ 2d ) and the combined male and parent component (ĥ 2 s+d ) at all age levels, was positive.The heritability values obtained are generally in the low to high category.
