The effects of genetic group, sex and system (litter vs. cage) on body measurements (shank and breast traits) and carcass characteristics were studied. Data of body measurements were collected at 6th week of age, and carcass traits were recorded at slaughter time at 10th week of age (except breast angle which was recorded at 8th week). All carcass traits and body measurements except shank were significantly affected by genetic groups (P CP - IRAN IN - LG - eng PB - JSTNAR PG - 69 PT - Research YR - 2000
