Estimation of Several Commercial, Phenotypic and Reproductive Traits' Performance, Using the Quantitative Genetic Method for Kamper Chicken Line

Abstract

In this study the genetic resource of Pelung chicken from Cianjur, West Java, Indonesia, was exploited. Pelung chicken has a higher body weight growth, unique meat flavor, and superior posture, compared with other indigenous breeds. Kamper chicken line selective breeding program was conducted, to increase the performance of Pelung breed by crossing with Layer Lohmann Brown-Classic. The Layer Lohmann Brown-Classic is an imported laying-type breed, which is widely known for its reproductive performance, based on the egg productivity. This study aims to use quantitative genetic method in estimating the commercial and reproductive traits' performance of Kamper chicken line. Based on commercial, phenotypic and reproductive traits, the progenies in Kamper chicken line have significant improvements, compared to the parental cross of Pelung and Layer Lohmann Brown-Classic. The quantitative genetic method was used in describing and underlying some phenomenon, in the selective breeding program. Although quantitative genetic method is utilized in basic breeding program with significant precision and rapidness, it is only used in the preliminary study, for the advanced type. Therefore, the addition of quantitative trait loci (QTL), provide a more thorough genetic examination, and play a role in selective breeding program.

Growth performance of Indonesian three-breed cross chicken associated with growth hormone and insulin-like growth factor 2 genes

“…One additional constraint encountered in the advancement of native chicken production in Indonesia is the scarcity of fundamental data on production, reproduction, heritability, genetic correlation, and phenotypic correlation [ 32 , 33 ]. Hence, the process of crossing native chickens necessitates the assessment of genetic parameters, where the backcross population is a unified breed population [ 34 , 35 ].…”
