| 摘 要： | 选用断乳仔猪45头,随机分为3组,每组5个重复,每个重复3头,采用完全随机化设计进行生长试验,研究了不同添加水平(5、125、250mg/kg)的硫酸铜日粮对猪下丘脑及中脑儿茶酚胺类物质分泌的影响。结果,日粮中添加125mg/kg(P<0.01)、250mg/kg(P<0.05)硫酸铜均显著提高了中脑、下丘脑多巴胺含量,但是随着铜水平的提高,多巴胺含量呈下降趋势;中脑黑质去甲肾上腺素浓度在试验组与对照组之间有显著差异,并且随着铜浓度的提高有升高趋势。据此推断,高剂量铜可能通过调节中枢儿茶酚胺代谢,促进生长激素的分泌进而促进动物生长。

| Abstract: | The experiment was conducted to examine effect of dietary copper supplementation on catecholamines secretion in the hypothalamus and midbrain of growing pigs.Forty-five crossbred pigs were randomly assigned to three groups of 15 pigs with each comprising 5 replicates of 3 animals.Pigs were allocated to diets that contained 5(as control),125 and 250 mg/kg sulphate copper.In result,the concentration of catecholamines was higher in pigs that were fed diets with 125(P<0.01)and 250 mg/kg sulphate copper(P<0.05),... |
