Abstract
These trials have indicated that gilt carcasses tend to be leaner than barrow carcasses and that boar carcasses are leaner than either barrow or gilt carcasses. As the hogs grow beyond 150 lb., these differences become more pronounced. Stilbestrol ear implants of either 1.5 mg., 3 mg. or 6 mg. at 150 lb. had minor effects on growth rate and feed utilization. A positive trend existed between amount of stilbestrol implanted and both size of Longissimus dorsi and percent of primal cuts. Copyright © . .
