| 摘 要： | 旨在研究不同锌水平日粮对生长期雄性梅花鹿饲料消化率和血液理化指标的影响。选取20头生长期雄性梅花鹿,随机分为5组。A为对照组,饲喂基础日粮;B、C、D、E组锌的添加水平分别为5mg/kg、15mg/kg、40mg/kg、100mg/kg,试验期90d。结果表明：（1）不同锌水平日粮对生长期雄性梅花鹿饲料干物质、粗蛋白质、粗脂肪、中性洗涤纤维和钙、磷的消化率均比A组有增强的趋势,但除中性洗涤纤维外,其它均未达到统计学差异显著水平（P〉0.05）。（2）不同锌水平日粮对生长期雄性梅花鹿血清锌和碱性磷酸酶活性影响极显著（P〈0.01）。（3）不同锌水平日粮对生长期雄性梅花鹿血清丙氨酸氨基转移酶、冬氨酸氨基转移酶和磷酸肌酸酶活性均有影响,但未达到统计学显著水平（P〉0.05）;对血清总蛋白、白蛋白和球蛋白的水平有随日粮加锌量的不同而呈增加趋势,但未达到统计学显著水平（P〉0.05）。综合不同锌水平试验鹿生理生化指标的变化,本次试验研究表明：锌的适宜添加量为15mg/kg。

| Abstract: | Twenty young sika deer（Cervus nippon）were assigned randomly into five groups, each group had five deer, and the single-factor experimental design was used to study the effects of different levels of zinc on feed digestibility and blood biochemical parameter.This experiment involved 5 dietary treatments,consisting of one control group fed basal diet and four levels of zinc which was 5mg/kg,15mg/kg, 40mg/kg,100mg/kg.The experimental period lasted 90 days.The results showed that：（1） The effects of different levels of zinc on the per-formance of the entire digestive tract digestibility of dry matter, crude protein, crude fat, neutral detergent fiber, calcium and phosphorus were higher than the group fed with basal diet, and that on neutral detergent fiber was significant differences（P 〈 0.05）.（2） The effects of different levels of zinc on the serum zinc and alkaline phosphatase activity was extremely significant（P 〈0.01）.（3） Different levels of zinc added into the feed of young deercould affect the activities of serum alanine aminotransferase, aspartate aminotransferase and creatine phosphate, but these were not significant（P 〉0.05）.The effects of different levels of zinc on total protein, albumin and globulin in serum were not significant（P 〉0.05）.All of the variety of physiological and biochemical parameters analyzed in each group indicated that the optimal supplementation of zinc was 15mg/kg by the dry matter in this experiment |
