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.
