ABSTRACT

The broiler trait viz., 6-week body weight (BW6) were recorded on 1315, 819, 1356 and 889 test cross progeny of 71, 69, 85 and 68 sire in G1, G2, G3 and G4 generation respectively. The 6-week body weight average of crossbred broiler ranged from 887.97±5.66 to 925.07±4.71g over the generations. The regression of heritability on generation number was significantly negative. Based on the mid-parent value, the superiority of test cross progeny were 5.79, 17.36, 12.62 and 24.05 per cent in G1, G2, G3 and G4 generation respectively.
