Data on 1602 broilers belonging to III Sires mated to 444 dams maintained at Poultry Research Centre of the University were utilized for the construction of conventional and restricted selection indices. The traits included were day old body weight, body weight at 5 and 8 weeks of age, feed consumption, weight gain and feed efficiency during 5–8 week. RIH value and aggregated genetic gain decreased due to restriction and the extent of decrease depended on the trait included in the index. Complete restriction in various combinations of all the traits included in the study individually and simultaneously were also studied. The index with complete restriction on body weight at 5 weeks had maximum RIH value (0.343) among all the restricted selection indices and this was 93.46 percent efficient in comparison to IG.
