Abstract

Production performance were measured on lambs fed with feed containing grape seed flour; weight gain, feed consumption and slaughtering parameters were recorded.

24 “Gentile di Puglia” lambs were divided into four homogeneous groups as regards weight; from the age of 50 days they were fed for a further 63 days on complete feeds in pellet form. The feeds contained 0, 10, 20 or 30% grape seed flour.

The feeds containing this by-product gave productive responses comparable to, or even better than, those obtained without by-product. A content of 10% grape seed meal in the feed produced weight gains and final live weights greater (P<0.05) than those produced by the control feed (261 g/d vs. 222 g/d and 34.016 kg vs. 31.533 kg). The use of up to 20% grape seed meal gave feed conversion indexes similar to those obtained using the control feed. Slaughtering data, pH measurements, dissection data and meat chemical composition were not influenced by the type of feed.

Interesting findings were obtained from the fatty acid composition, which showed that increasing levels of inclusion of grape seed flour in the feed decreased saturated fatty acids, increased unsaturated fatty acids and improved dietary characteristics of the meat with the best indices of atherogeniticy and thrombogenicity.

葡萄籽粉在羔羊饲料中的应用及其对生产性能和肉品质的影响
用含葡萄籽粉饲料饲喂羔羊,测定其生产性能;记录增重、饲料消耗和屠宰参数外邦羔羊按体重分为四组;从50日龄开始,再饲喂63天的颗粒状全饲料。饲料中含有0%、10%、20%或30%的葡萄籽粉。含有这种副产物的饲料的生产反应与没有副产物的饲料相当,甚至更好。饲料中添加10%葡萄籽粕的增重和最终活重均高于对照饲料(261 g/d对222 g/d, 34.016 kg对31.533 kg) (P<0.05)。葡萄籽粕添加量达到20%,饲料转化率与对照饲料相近。屠宰数据、pH值测量、解剖数据和肉类化学成分不受饲料类型的影响。在脂肪酸组成方面得到了有趣的发现,饲料中葡萄籽粉添加水平的增加减少了饱和脂肪酸,增加了不饱和脂肪酸,改善了肉的膳食特性,具有最佳的动脉粥样硬化和血栓形成指标。
