| 摘 要： | 本研究在绵羊日粮中添加一定量的葡萄皮渣，旨在研究其对绵羊生长性能、器官指数及血液生化指标的影响。试验选取24只5月龄、体重25 kg左右的杜泊羊×小尾寒羊杂交公羊，采用完全随机设计分为4组，每组6只，分别饲喂不同葡萄皮渣添加水平（0、5%、10%、20%）日粮。结果表明，10%添加组日增重（ADG）显著高于0、5%添加组（P<0.05）；10%添加组肝脏及肾脏重量显著高于0、5%添加组（P<0.05）；10%和20%添加组的大肠重量显著高于其他两组（P<0.05）；添加葡萄皮渣能极显著增加皱胃重量（P<0.01）。适量添加葡萄皮渣能显著提高绵羊血清高密度脂蛋白胆固醇（HDL-C）含量，其中以10%添加水平最高（P<0.05）；谷丙转氨酶（ALT）与谷草转氨酶（AST）变化趋势相同，均以5%添加组最低，显著低于0、20%添加组（P<0.05）；与未添加组相比，5%添加组绵羊血清肌酐（CRE）含量显著降低（P<0.05），而总抗氧化能力（T-AOC）明显提高（P<0.05）；过氧化氢酶（CAT）活性以20%添加组最高，显著高于其他3组（P<0.05）。由以上结果可知，日粮中添加一定量的葡萄皮渣可提高绵羊日增重，促进肝脏、肾脏及消化器官的发育，增加血清高密度脂蛋白胆固醇含量，提高血清抗氧化水平。综合各个指标，葡萄皮渣添加量以10%为宜。 |

| Abstract: | This experiment was aimed to investigate the effect of grape pomace on growth performance,organ index and blood biochemical indexes in sheep.A total of 24 hybrid 5-month-old Dorper (♂)×Small Tail Han sheep (♀) F1 male lambs weighted at 25 kg were randomly divided into 4 groups with 6 lambs per group.All these sheep were fed diets with the addition of grape pomace at 0,5%,10%,20% on a dry weight basis, respectively.The results showed that the ADG in group 10% was extremely significantly higher than that in group 0 and 5% (P<0.01),and the weights of liver and kidney in group 10% were notably higher than that in group 0 and 5% (P<0.05).The weights of large intestinein in group 10% and 20% were obviously higher than that in the other two groups (P<0.05).The weights of abomasum were extremely significantly increased in grape pomace supplemental groups (P<0.01).Grape pomace could significantly improve serum HDL-C,and it was the highest in group 10% (P<0.05).ALT and AST had the same variation trend,they were the lowest in group 5%,and the values in group 5% were significantly lower than that in group 0 and 20% (P<0.05).Compared with group 0,the serum CRE in group 5% was significantly decreased (P<0.05),while the serum T-AOC significantly improved (P<0.05).The CAT enzyme activity was highest in group 20%,it was higher than the other groups (P<0.05).In conclusion,adding grape pomace properly could improve ADG,promote development of liver,kidney and digestive organs,increas serum HDL-C level,and improv the level of serum antioxidant.Taking all factors into account,dietary supplementation with 10% of grape pomace was advisable. |
