Heart girth, width of hip, height of wither and body length together accounted for 82.76% of the variability in liveweight at one year and 85.51% of the variability at two years. Heart girth was the best single predictor of weight at one year and width of hip bone was the best predictor at two years. Both, when included together, accounted for 80% of the variability in liveweight at the two ages studied. Differences in the carcass composition as affected by the production system and copra cake supplementation were observed in all traits studied except for fat thickness and marbling score. From the data analysed, first grade meat constituted 60.06%, second grade meat constituted 8.05% and saleable bones and edible trimmed fat constituted 14.0% of the total hot carcass weight
