Abstract The objective of this study was to evaluate the quality of the meat of lambs submitted to diets with grape pomace silage (GPS) in substitution of the whole plant corn silage. Twenty four male lambs were distributed in four diet treatments with increasing levels of GPS, using a forage:concentrate ratio of 50:50. The diet treatments were characterized for chemical composition, and the lamb meat was evaluated for proximate composition, fatty acids profile, oxidative stability, color and sensory attributes. Changes in the lipid fraction, fatty acid profile, cholesterol levels and oxidative parameters of meat (p 0.05) in the sensory parameters. The GPS used in this study may be an alternative as a forage feed in the diet of lambs with benefits in the quality and oxidative stability of lamb meat, without affecting the sensory attributes.

用越来越多的葡萄渣青贮饲料喂养的羔羊：对肉质的影响

摘要 本研究的目的是评估用葡萄渣青贮饲料 (GPS) 代替全植物玉米青贮饲料饲喂的羔羊肉的质量。使用 50:50 的草料：精料比例，将 24 只雄性羔羊分配到四种日粮处理中，并增加 GPS 水平。饮食处理以化学成分为特征，羊肉评估了近似成分、脂肪酸谱、氧化稳定性、颜色和感官属性。感官参数中肉的脂质分数、脂肪酸谱、胆固醇水平和氧化参数的变化 (p 0.05)。本研究中使用的 GPS 可能是羔羊日粮中的一种替代饲料，对羊肉的质量和氧化稳定性有好处，而不会影响感官特性。
