This study investigated the effects of feeding graded levels of sun-dried red grape pomace (GP; 0, 5, 10, 15 and 20%) on growth, carcass and meat physico-chemical quality attributes of Dohne Merino lambs for 42 days. Dry matter intake increased quadratically with a critical value (i.e., optimum inclusion level) of 11.3% GP (P ≤ 0.05). Diet exhibited similar quadratic responses for average daily gain, live, hot and cold carcass weights with optimum inclusion levels at 9.6, 9.7, 12, 2 and 12.1, respectively (P ≤ 0.05). Overall, meat quality traits were not negatively affected by GP inclusion (P > .05). Gross profit was influenced by diet, with an optimum inclusion level at 12.2% (quadratic; P ≤ 0.05). Overall, inclusion of 12.2% GP in lamb finishing diets at the expense of oat bran and wheat bran middlings improved lamb productivity, without compromising meat quality.

这项研究调查了饲喂分级等级的晒干的红葡萄果渣（GP； 0、5、10、15和20％）对42天多纳美利奴羊羔的生长，car体和肉理化品质属性的影响。干物质摄入量以GP的11.3％的临界值（即最佳夹杂物含量）二次增加（P≤0.05）。饮食对平均日增重，活体，热和冷cas体重量表现出相似的二次响应，最佳夹杂物含量分别为9.6、9.7、12、2和12.1（P≤0.05）。总体而言，GP的添加不会对肉品质量产生负面影响（P> .05）。毛利受饮食影响，最佳包容度为12.2％（二次方； P≤0.05）。总体而言，以燕麦麸和小麦麸皮为代价，在羔羊粗饲料中添加12.2％的GP可以提高羔羊的生产力，
