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.
