本试验研究了铜、锌源对肥育猪生长性能、养分消化率、胴体性状和肉质性状的影响。日粮处理包括1）无机铜（CuSO 4中心点5 H（2）O 30 ppm），2）有机铜（Cu-蛋氨酸，30 ppm），3）无机锌（ZnO，80 ppm）和4）有机锌（Zn-蛋氨酸，80 ppm）。与铜蛋氨酸和锌蛋氨酸处理相比，氧化锌处理提高了ADFI（平均日采食量）（p 0. 05）。5周后，各处理间DM和N消化率差异不显著（p>0.05）.试验结束时，与其他3个处理相比，Zn-met处理降低了DM和N的消化率。CuSO_4处理组猪肉pH值高于Zn-met和ZnO处理组（p
This study investigated the effects of copper and zinc sources on growth performance, nutrient digestibility, carcass traits and meat characteristics in finishing pigs. Dietary treatments included 1) inorganic copper (CuSO4 center dot 5H(2)O 30 ppm), 2) organic copper (Cu-methionine, 30 ppm), 3) inorganic zinc (ZnO, 80 ppm) and 4) organic zinc (Zn-methionine, 80 ppm). ZnO treatment improved the ADFI (average daily feed intake) compared to Cu-met and Zn-met treatments(p0.05). DM and N digestibility were not Significantly different among the treatments after 5 weeks (p>0.05). At the end of the experiment, DM and N digestibility were decreased with Zn-met treatment relative to the other three treatments. The pH value of meat from CuSO4 treated pigs was greater than Zn-met and ZnO treated pigs (p
