- The difference between a feather conditions, namely naked neck and normal feathered in chicken gives the qualitatively genetic differences by Na gene and its allele na. This study was conducted to analyze the relationship between the condition of the feather and of reproductive potential. Five males of Naked neck, each paired with four females of Naked neck and two females of Normal. Production of eggs from each female were collected and then incubated, to studies the reproductive potential through egg fertility and hatchability. Completely randomized designs by the variance analysis were used to determine the effects of the feather conditions, and the hierarchical analysis of variance was to determine of the genetic potential. The results showed that the feather conditions did not significantly affect the egg production. The fertility of naked neck chicken (95.72±03.88%) was significantly higher (P<0.05) than normal chicken (92.67±10.61%) and the hatchability of naked neck chicken (73.69±21.69%) was significantly lower (P<0.05) than normal chicken (83.76±04.84 %). Embryo mortality of naked neck chicken (19.85±11.04%) was significantly higher (P<0.05) than normal chickens (17.97±11.50%). Eggs weight and doc weight did not show a significant difference. Heritability of egg weight in chickens was low (h2 = 0.07), and the repeatability (R = 0.69) was quite high. The heritability of doc was underestimated (h2 = -0.19), although the repeatability was still high (R = 0.59). Keywords: Naked Neck and Normal Native Chicken, production, reproduction, repeatability and heritability.
