摘　　要：本文旨在研究不同形式铜对雄性梅花鹿血清生化指标及营养物质消化率的影响,进而筛选出在梅花鹿日粮中铜的最适宜添加形式。选取20头2年生梅花鹿随机分成4组(A组、B组、C组和D组),按照能量相近、营养物质一致、铜添加量均为10 mg/kg(铜离子)的基础下,研究硫酸铜(B组)、柠檬酸铜(C组)和蛋氨酸铜(D组)3种铜源对雄性梅花鹿血清生化指标及营养物质消化率的影响。试验结果表明:1)蛋氨酸螯合铜组对干物质、粗蛋白质及钙的消化率高于另外3组(P>0.05);蛋氨酸螯合铜组对磷的消化率极显著高于其对照组和硫酸铜组(P<0.01);2)蛋氨酸铜组血清铜含量极显著高于另外3组(P<0.01),毛中铜含量高于基础日粮组和硫酸铜组(P<0.05),粪中铜含量低于硫酸铜组和柠檬酸铜组(P<0 .01);3)不同铜源影响总蛋白质、白蛋白、碱性磷酸酶、谷丙转氨酶、谷草转氨酶活性,但各组间差异不显著(P>0.05),各组间血糖含量差异不显著(P>0.05);4)蛋氨酸铜组铜蓝蛋白活性、超氧化物歧化酶活性显著高于基础日粮组(P<0.05)。结果表明,梅花鹿饲粮中最适宜的添加铜源为蛋氨酸铜。The aim of the present study was to investigate the effects of different copper sources on serum biochemical parameters and the digestibilities of nutrients in growing male sika deer. Twenty 2-year-old growing male sika deer were randomly allotted to four groups （A,B,C,and D） and to study the effects of copper sulfate （group B）,copper citrate （group C） and methionine copper （group D） on serum biochemical parameters and nutrient digestibilities. Groups B,C and D were experimental groups and fed diets added 10 mg/kg （copper ion） copper sulfate,copper citrate and methionine copper according to the same energy and nutrient,respectively. The results showed that,1） the digestibilities of crude protein,calcium in the group of methionine copper were higher than those in other groups （P0.05）; the digestibility of phosphorus in groups C and D was higher significantly than that in other groups （P0.01）; 2） serum copper of male sika deer fed methionine copper was higher than that in other groups （P0.01） and copper in pelage was significantly higher than that in groups A and B （P0.05）,and fecal copper excretion was lower than that in groups B and C; 3） the effect of different copper sources on the activities of total protein,albumin,alkaline phosphatase,alanine aminotransferase,aspartate aminotransferase in serum were not significantly changed （P0.05）; 4） the effect of methionine copper on the activities of ceruloplasmin and superoxide dismutase were significantly higher than those in group A （P0.05）. It was concluded that methionine copper was the appropriate form in sika deer diet.
