铜对1～4周龄五龙鹅脂类代谢、抗氧化能力及免疫器官指数的影响
Effects of Copper on Lipid Metabolism,Antioxidant Ability and Immune Organ Indexes of Wulong Geese Aged from 1 to 4 Weeks
摘要
Abstract
This experiment was conducted to study the effects of copper on lipid metabolism,antioxidant abili-ty and immune organ indexes of Wulong geese at the aged of 1 to 4 weeks,and to find the optimum copper level in diets. A total of 360 one-day-old Wulong geese were divided into 6 groups with 6 replicates per group and 10 geese per replicate. Geese in the groupⅠ(control group)were fed a basal diet( copper content was 6.43 mg/kg),and geese in the experimental groups( groups Ⅱ to Ⅵ)were fed the basal diet supplemented with 15,30,60,120 and 240 mg/kg copper,respectively. The experiment lasted for 4 weeks. The results showed as follows:1)compared with control group,serum total cholesterol,triglyceride and low density lipo-protein-cholesterol contents in group Ⅲ were significantly decreased( P<0.05),and high density lipoproteins-cholesterol content was significantly increased( P<0.05). 2)Compared with control group,total anti-oxidative capacity,the activities of CuZn superoxide dismutase( CuZn-SOD)and copper-protein( CP)and immune or-gan indexes in group Ⅱ were significantly improved( P<0.05 or P<0.01). 3)Serum CuZn-SOD and CP ac-tivities had significant positive correlation with the immune organ indexex(P<0.05 or P<0.01). In conclu-sion,adding 15 mg/kg copper in the diet has significant effects on lipid metabolism,antioxidant ability and immune organ indexes of Wulong geese aged from 1 to 4 weeks. It has a correlation among body antioxidant enzyme activity,lipid metabolism and immune organ indexes in some extent.关键词
