Effects of triticale-based diets on finishing pig performance and pork quality in deep-bedded hoop barns

摘要

Effects of triticale diets on pig performance and pork quality were evaluated in summer and winter. Diets were: corn-soy, 40% triticale, or 80% triticale. Pigs (72 kg) were fed 49 d. Loins were evaluated for meat and fat quality and sensory evaluation. Average daily gain decreased as triticale inclusion increased (P < 0.01). Feed intake was similar. Pigs fed corn-soy had the greatest and those fed 80% triticale had least gain:feed ratio (P < 0.05). In summer, pigs fed corn-soy had largest and those fed 80% triticale diet had smallest loin muscle area (P < 0.05) based on ultrasound scan. During summer, ultimate pH was higher (P ≤ 0.001) and, loin purge and shear force were lower (P < 0.05). Diet did not affect sensory evaluation or fatty acid profile of loins. During summer, total MUFA were more and total PUFA were less (P ≤ 0.01). Triticale fed to pigs in hoop barns slightly decreased growth without compromising pork quality.
