Abstract:

本试验旨在研究饲粮铜源及水平对育成期雄性水貂生长性能、营养物质表观消化率及氮、铜代谢的影响。采用3×3+1双因素试验设计,设3种铜源(硫酸铜、碱式氯化铜、蛋氨酸铜)和3个铜添加水平(10、25、40mg/kg),1个对照组。选择60日龄健康、体重接近的美国短毛黑雄性水貂120只,随机分成10组,每组12个重复,每个重复1只貂。预试期7d,正试期45d。结果表明:1)水貂的平均日采食量随饲粮铜添加水平的增加呈极显著线性增加(P<0.01),并且平均日增重随饲粮铜添加水平的增加也呈线性增加(P=0.053)。2)水貂的粗脂肪表观消化率随饲粮铜添加水平的增加呈极显著线性增加(P<0.01),并且粗蛋白质表观消化率随饲粮铜添加水平的增加也呈显著线性增加(P<0.05)。3)水貂铜摄入量、粪铜排泄量、尿铜排泄量以及铜沉积量均随饲粮铜添加水平的增加呈极显著线性增加(P<0.01),然而铜的表观吸收率却随饲粮铜添加水平的增加呈极显著线性降低(P<0.01)。水貂对碱式氯化铜和蛋氨酸铜的表观吸收率极显著高于对硫酸铜的表观吸收率(P<0.01)。水貂氮沉积量随饲粮铜添加水平的增加而呈显著线性增加(P<0.05)。由此可见,基础饲粮中铜含量为8.05mg/kg时,饲粮添加40mg/kg的铜能改善育成期雄性水貂生长性能,提高水貂粗脂肪表观消化率;育成期雄性水貂对碱式氯化铜和蛋氨酸铜的表观吸收率高于对硫酸铜的表观吸收率。
