Comparative evaluation of male line of Vanaraja, control broiler, Vanaraja commercial in respect to juvenile and carcass quality traits

Abstract

A study was conducted to evaluate male line of Vanaraja, Control broiler, Vanaraja commercial in respect to juvenile and carcass quality traits. Data for the present study was taken on 1022 birds. Different juvenile traits recorded up to 6 weeks of age and carcass quality traits were measured at 8 weeks of age. Significant (P<0.05) difference between male and female chicks were observed at day old, 2, 4 and 6 weeks of age in Vanaraja. However, male line of Vanaraja (PD1) and Control Broiler showed significant (P<0.05) difference between male and female for 2, 4 and 6 weeks of age. Shank length at 6 weeks of age showed significant difference between male and female in all the three genetic groups. Body weight recorded at day old, 2,4 and 6 weeks of age showed significant difference between different genetic groups irrespective of sex. Carcass quality showed significant (P<0.05) difference for pre slaughter live weight. However, blood, feather, head, shank+feet, eviscerated carcass, giblet and abdominal fat expressed as % of pre slaughter live weight %, did not showed any statistical difference between the genetic groups. Cut up parts expressed as % of eviscerated carcass weight showed only significant (P<0.05) difference for breast cut between the different genetic groups. Sensory evaluation did not showed any statistical difference between the genetic groups for any of the attributes. It is concluded that PD1 growth and shank length were lower than the Control broiler and Vanaraja commercial and there exist significant (P<0.05) difference between male and female in a genetic groups and between genetic groups for juvenile body weight. Carcass quality study did not show any significant difference between genetic groups except breast cut %.
