Keyword:  有机微量元素添加荆肥育猪生产性能;
Abstract: 选择有机微量元素添加剂对64头育肥猪(内江×杜洛克),随机分4个处理组:处理1组(对照组),添加常规微量元素添加剂;处理2,3,4组分别添加有机微量元素添加剂0.15%,0.11%,0.08%(占饲食).经65天试期后(屠宰测定及粪便收集)结果:胴体生产性能特征各处理组之间差异不显著;四个粪便收集期测试粪中铜、铁、锌的排泄量,铜:其他各组与对照组比较各收集期都显著降低(P<0.05);铁:其他各组与对照组比较(除4组第四收集期无显著差异外),排泄量显著降低(P<0.05);锌:其他各组与对照组比较(除2组,3组第四收集期无显著差异外)排泄量显著降低(P<0.05).猪育肥阶段使用有机微量元素添加剂,不影响总体生产性能,可有效降低重金属的排泄量.
