The aim of this work was to evaluate muscle, fat and bone growth in D x (LW x L) pigs from 80 to 160 kg of live weight (LW). A growth study was carried out using 18 castrated males (CM) and 18 females (F). The animals were raised individually and fed from 80 to 160 kg LW with a diet containing 137.8 g/kg of crude protein, 8.2 g/kg of lysine and 3.2 Mcal/kg of digestible energy. Diet was fed at 8% of LW 0 . 7 5 . At 80 kg of LW and after 56 and 139 days (approximatively at 120 and 160 kg of LW), six CM and six F pigs were slaughtered. Carcass fractions were weighed and analyzed for water, crude protein, fat, ash and gross energy contents. Empty body was analyzed for lysine, methionine, cystine and threonine contents. Differences between sexes were found for average daily gain (F: 766 g/day and CM: 706 g/day; P < 0.03) and feed/gain ratio (F: 3.36 and CM: 3.65; P < 0.02) from 80 to 120 kg LW for LW (F: 170.8 kg and CM: 161 kg; P < 0.01) and feed/gain ratio (F: 3.02 and CM: 2.95; P < 0.01) from 80 to 160 kg LW. Efficiency of protein deposition in lean tissue, lean tissue daily gain and daily protein retention from 80 to 160 kg LW were 54.8%, 224 g/day and 96 g/day respectively. Differences between sexes were also found for lysine retention (F: 8.7 g/day; CM: 6.8 g/day; P < 0.05) and fat deposition (F: 172 g/day; CM: 209 g/day; P < 0.05) in empty body weight, from 80 to 120 kg LW, and fat deposition from 120 to 160 kg LW (F: 307 g/day and CM: 347 g/day; P < 0.01).
