Daftar Isi:
- Single nucleotide polymorphisms of C1032T of insulin-like growth factor binding protein 2 (IGFBP2) gene was used to genotype Kampung chickens by PCR-RFLP method. Four pairs mating based on genotype of the chickens were arranged to produce progenies which were characterized according to the genotype of their parents. Variance components and genetic parameter of four weeks interval of growth rate (0-4, 4-8, 8-12 weeks) of the progeny were evaluated with classical models of quantitative genetics. The result showed that four weeks interval of growth rate were sex, interval growth rate and genotypes dependent. Allele contribution value and the average of allele effect indicated that allele C was higher than allele T during 0-4 weeks interval of growth rate, and during 8-12 weeks interval of growth rate, allele T was higher than allele C for both females and males chicken. Heritability based on half-sib component was low during 0-4 and 4-8 weeks interval of growth rate (0.02 and 0.04, respectively) and moderate (0.41) for 8-12 weeks interval of growth rate. Heritability based on genetic variance component of 0-4; 4-8; 8-12 weeks interval of growth rate for female was 0.115; 0.383; 0.015, and for male was 0.904; 0.642 and 0.802, respectively. It is concluded that heritability based on genetic variance component is higher than that based on half-sib component. Key Words: Kampung chicken, Growth rate, Heritability
