| 摘 要： | 为了研究日粮铜水平对鹅血液和组织中铜含量的影响,试验将1周龄的四川白鹅随机分为4组,1、2、3、4组分别饲喂铜水平为39.55,127.60,194.75,255.22 mg/kg的日粮,在鹅4,6,8,10,12周龄时对血液、肝脏、胸肌和皮下脂肪中的铜含量进行测定,然后采用多因素方差分析方法分析日粮铜水平、周龄与性别三因素对鹅血液和组织中铜含量的影响.结果表明,日粮铜水平对鹅血液、肝脏中的铜含量无显著影响(P＞0.05),而2组(饲喂铜水平为127.60 mg/kg日粮)鹅胸肌铜含量显著高于1组(饲喂基础日粮,铜水平为39.55 mg/kg) (P＜0.05),4组(饲喂铜水平为255.22 mg/kg日粮)鹅皮脂中铜含量极显著高于其他3组(P＜0.01);另外,周龄对鹅血液、肝脏、胸肌和皮脂中的铜含量均有极显著影响(P＜0.01);性别因素对鹅血液和组织中的铜含量没有显著影响(P＞0.05).

| Abstract: | In order to study the effect of dietary copper level on blood and tissue copper contents in geese,one-week Sichuan white geese were randomly divided into four groups,and the geese in the first,second,third and fourth groups were fed with diet with copper levels of 39.55,127.60,194.75 and 255.22 mg/kg,respectively.At the ages of 4,6,8,10 and 12 weeks,the contents of copper in blood,liver,chest muscle and subcutaneous fat of the geese were determined.The effects of dietary copper level,age and sex on the blood and tissue copper contents of geese were analyzed by multivariate analysis of variance.The results showed that the dietary copper level showed no significant effects on the blood and liver copper contents of geese (P＞0.05);the chest muscle copper content of geese in the second group was significantly higher than that in the first group (P＜0.05);the subcutaneous fat copper content of geese in the fourth group was significantly higher than those in the other three groups (P＜0.01);the age had significant effects on the blood,liver,chest muscle and subcutaneous fat copper contents of geese (P＜0.01);and the sex showed no significant effects on the blood and tissue copper contents of geese (P＞0.05). |
