Present study was undertaken to compare the male line of Vanaraja, Vanaraja and control broiler in respect to
their juvenile traits and to study the genetic parameters in Vanaraja male line (PD1). Body weight, feed conversion,
conformation traits and carcass quality were measured. Body weights showed significant difference between different
genetic groups and lowest body weight recorded in Vanaraja followed by PD1 and control broiler. The gain in body
weights at 2 weeks interval showed significant difference between genetic groups and also differ significantly at
different periods within a genetic group. All the conformation traits studied showed significant differences between
genetic groups and for increase in shank and keel length during different periods. FCR was significantly better in
PD1 and control broiler than Vanaraja. Carcass quality traits measured at 12 weeks of age showed significant
difference for abdominal fat% and back+neck% between PD1 and Vanaraja. Vanaraja recorded significantly lower
abdominal fat% compared to PD1. Heritability estimates for juvenile body weights in PD1 were moderate in
magnitude. All conformation traits showed low to moderate estimates of heritability in magnitude for the traits
measured at different ages. Correlations for body weights with different conformation traits were high in magnitude.
Correlations between the same traits measured at different weeks showed positive and high correlation. The results
revealed that the selection in PD1 may improve the performance of the line and also improve the performance in
Vanaraja which is being used as dual purpose backyard poultry through utilization of heterosis for different traits.
