Abstract
615 chicks were taken in the three hatches using the progeny of 96 females and 16 males as parents. The means for conformation traits were 8.60±0.02, 10.64±0.10 cm for keel length at 6 weeks and 8 weeks of age, respectively. The shank length at 6 and 8 weeks of age was 6.62±0.01 and 8.72±0.03 cm respectively. The breast angle at 6 and 8 weeks of age was 71.43±0.15 and 79.53±0.15. The effect of hatch was found to be highly significant on body conformation traits. The heritability estimates for keel length and shank length both at 6 weeks of age was found to be 0.436±0.174 and 0.575±0.210, respectively. The genetic correlations of keel length at 6 weeks with 8 weeks and shank length at 6 weeks were positive and high. Positive and high association was observed between breast angle at 6 and 8 weeks of age.
