Abstract
A study on genetic aspects of Residual Feed Consumption (RFC) was carried out at C.P.R.S., Anand using 414 and 454 pedigreed pullets belonging to 37 and 30 sire families of synthetic flock of WLH birds in S1 and S2 generation respectively. The mean RFC or accumulated RFC was not significantly different from zero during 4 weekly interval in both generations (range for RFC during 4 weekly periods were - 10.0 to 11.562 in S1 while - 9.981 to 9.013 in S2 generation birds). Mean cumulative RFC during 21-40, 21-56 and 21-72 weeks periods were -0.199, -0.191 and - 0.339 gm while -0.208, -0.250 and 0.010 gm in S1 and S2 generations respectively. Also coefficient of determinations (R2 values) were found lower viz. 0.50 to 10.7 % in S1 generation whereas 1.0 to 10.4 % in S2 generation.
