Abstract

Effects of sex class (physically castrated, PC or immunologically castrated, IC) and diet (0 or 5. mg/kg ractopamine hydrochloride, RAC) on characteristics of ham and bellies were determined from pigs slaughtered in three groups with similar ending live weights. One carcass per pen per marketing group (n = 8) was selected to evaluate further processing characteristics. Data were analyzed as a 2. ×. 2 factorial design with a split plot in time and fixed effects of sex, diet, marketing group, and their interactions. IC fresh bellies were thinner ( P< 0.01) and softer ( P< 0.01) than PC bellies. IC hams and bellies were leaner ( P< 0.05) than those from PC pigs. RAC feeding did not affect ( P> 0.05) fresh ham or belly characteristics but decreased ( P<. 0.01) fat in cured PC bellies. Marketing group affected ( P< 0.05) fresh quality, processing characteristics, and composition of hams and bellies. Immunological castration and RAC produced leaner finished products but did not alter processing yield of hams or bacon.
