ESTIMATION OF Na GENE FREQUENCY ON NATIVE CHICKEN POPULATION AND ITS EFFECT ON HATCHABILITY PERFORMANCE
Abstract: The objective of
this research was to estimate the Na gene frequency of the native
chickenpopulation and its effect on hatchability performance. The research used
Native Chickens with Nakedneckphenotype and Normal-feathered Native Chicken,
consisted of 16 cocks and 48 hens as the parent.They were put in 4 breeding
groups : 1) Breeding group of Legund Cock with Legund Hen (LL); 2)Legund Cock
with Normal-feathered Native Hen (LN); 3) Normal-feathered Native Cock with
LegundHen (NL); 4) Normal-feathered Native Cock with Normal-feathered Native
Hen (NN). Each groupconsisted of 4 replications and each replication consisted
of 1 Cock with 3 Hens. CompletelyRandomized Design (CRD) were used to analysis
the fertility, hatchability and embryo mortality.Hardy-Weinberg’s Law of Gene
equilibrium method was used to find out the spreading estimation of Naand na
gene in whole offspring population. Experimental result showed that the
breeding groups had noinfluence (P>0.05) on egg fertility, hatchability and
embryo mortality. The phenotypes of the offspringof the breeding groups were
not deviate from the Mendel’s law. The estimation of the Na gene frequencywas
19.7%.
