The aim of this study was to evaluate the effect of association of forage cactus meal (CM) and cunhã hay (CH) on carcass traits, meat quality, and fatty acid (FA) profile of goats. Twenty-four goats were finished on diets composed with the association of CM and CH (83% CH + 17% CM, 67% CH + 33% CM, or 50% CH + 50% CM), corresponding to 60% of the total diet; the remainder was composed of 10% elephant grass and 30% concentrate. The control treatment consisted of 70% elephant grass and 30% concentrate. Carcass yield and commercial cut weight were higher in the animals fed CH and CM at any concentration (P < 0.05). Animals fed with intermediate and high CM content resulted in meat with better proportions of unsaturated FA (P = 0.0281), desirable FA (P = 0.0024), omega 6/omega 3 ratio (P = 0.0340), and hypo-/hypercholesterolemic index (P = 0.0140). The inclusion of CH and CM provided carcass yield and FA profile more favorable for consumer market and human health.
本研究的目的是评估饲用仙人掌粉（CM）和库尼亚干草（CH）组合对山羊胴体性状、肉质和脂肪酸（FA）谱的影响。24只山羊采食由CM和CH组合而成的日粮（83% CH + 17% CM、67% CH + 33% CM或50% CH + 50% CM），占日粮总量的60%；其余部分由10%的象草和30%的精料组成。对照处理由70%的象草和30%的精料组成。采食任何浓度CH和CM的动物胴体产量和商业切块重量均较高（P < 0.05）。采食中等和高CM含量的动物所产肉中不饱和FA比例更佳（P = 0.0281）、有益FA比例更佳（P = 0.0024）、ω6/ω3比值更佳（P = 0.0340）以及胆固醇过低/过高指数更佳（P = 0.0140）。添加CH和CM可提供更有利于消费市场和人类健康的胴体产量和FA谱。
