Grape pomace (GP) is an inexpensive natural antioxidant promising as animal feed supplement due to its high content of phenolic compounds. In order to evaluate its effect in lactating ewe rations on meat quality and fat composition of their suckling lambs, 48 Churra ewes were divided into 4 treatments. All animals were fed a ration containing linseed oil (Control) supplemented with Vitamin E or two levels of GP. Lambs were nourished exclusively by suckling until they were slaughtered. Dietary GP did not generate adverse effects on carcasses or lambs meat quality when compared with Control or Vit-E diets. GP improved the water holding capacity of the meat. In addition, lambs meat FA profile was not nutritionally affected with the diets assayed. Hence, the use of GP as a dietary supplement in ewe rations would not have negative effects on meat from suckling lambs.
葡萄渣(GP)是一种廉价的天然抗氧化剂,由于其酚类化合物含量高,有望作为动物饲料的补充剂。为了评估其在哺乳期母羊日粮中的效果,对其哺乳羔羊的肉质和脂肪组成的影响,将 48 只 Churra 母羊分为 4 个处理组。所有动物都喂食含有亚麻籽油(对照)的日粮,并补充维生素 E 或两种水平的 GP。羔羊仅通过哺乳喂养,直到被屠宰。与对照或 Vit-E 饮食相比,日粮 GP 对胴体或羔羊肉质没有产生不良影响。GP 提高了肉的保水能力。此外,日粮中添加 GP 对羔羊肉的 FA 谱没有营养影响。因此,将 GP 作为母羊日粮中的补充剂使用不会对哺乳羔羊的肉产生负面影响。
