dc.description.abstractWhite Leghorn birds of IWN strain maintained at Poultry Complex, Veterinary College, Anand were utilized as experimental material for present study. During 17th week of age, before they started to lay eggs, the birds were transferred to individual California cage system for individual recording of performance. Various traits required for present study were measured at different periods of age. Average for age at first egg was 150.14 days'whereas, averages for body weight at 20, 40 and 56 weeks of age were 1204.49 g, 1520.02 g and 1549.59 g, respectively. The mean values for total egg number produced upto 40 and 56 weeks of age were 118.40 eggs and 211.92 eggs, respectively. The mean values for egg weight at 40 and 56 weeks of age were 51.60 g and 52.45 g , respectively. The averages for total feed consumption from 21 to 40 and 21 to 56 weeks of age were 15.323 kg and 26.913 kg , respectively. The mean values for Income Minus Feed Cost (IMFC) per bird from 21 to 40 and 21 to 56 weeks of age were Rs. 7.63 and Rs. 27.15, respectively. Income Minus Feed Cost (IMFC) was found highly heritable and the heritability estimate for IMFC21-40 and IMFC21-56 was found to be 0.41 and 0.42, respectively. Genetic and phenotypic correlations between Income Minus Feed Cost and the associated traits analyzed were in a favourable direction. Encouraging results observed from present study indicate that Income Minus Feed Cost (IMFC) can be used as a selection criterion for necessary overall improvement of layer stocks for commercial exploitation as per recent need of poultry industry.en_US
