Western Research and Demonstration Farm
Six hundred crossbred gilts and barrows were finished in hoop structures with a stocking density of either 7.5 ft2 per pig or 12.0 ft2 per pig. Performance and growth data including ADG, feed conversion (feed:gain), slaughter weight, shrink percentage during transport and lairage, dressing percentage, loin eye area, 10th rib backfat thickness, last rib fat depth, and fat free lean percentage were analyzed to determine effects of stocking density on growth and carcass traits. Increasing the stocking density from 12 to 7.5 ft2 /pig in hoop structures did not affect growth performance, carcass composition, or fresh pork quality.
