摘　　要：试验选用产前4周的长白×大约克母猪72头,随机分成3组。试验共设3个日粮处理：添加100%CuSO4.5H2O（对照组）、30%蛋白质螯合铜＋70%CuSO4.5H2O（30%百乐铜组）和100%蛋白质螯合铜（100%百乐铜组）,各日粮处理的Cu含量一致,研究有机微量元素蛋白质螯合铜对母猪繁殖力及其仔猪生长性能的影响。试验分妊娠期（1~28 d）和哺乳期（29~50 d）两阶段。结果表明：（1）日粮添加百乐铜可明显地减少母猪哺乳失重,有利于改善仔猪初生重（P〉0.05）;30%百乐铜组仔猪断奶重显著高于对照组和100%百乐铜组（P〈0.01）;（2）百乐铜可提高母猪日粮微量元素的消化率（P〉0.05）,改善日粮干物质的消化率（P〈0.01）;（3）100%百乐铜组母猪所产仔猪在14日龄（P〉0.05）和21日龄（P〉0.05）阶段均呈现血清Zn,Fe,Mn和Cu微量元素水平明显提高,证明母猪日粮添加百乐铜后Cu及其他微量元素的生物利用率得到提高和改善。结果表明：母猪日粮添加有机形式的蛋白质螯合铜——百乐铜可明显地提高仔猪血清微量元素水平,并随仔猪的生长发育,微量元素体况和贮备维持在一个较高的水平上。A total of 72 sows（Landrace×Yorkshine） with similar parity were selected and randomly assigned to 3 treatments.Three experimental diets including control,30% Bioplex Cu diet and 100% Bioplex Cu diet were used to study the effects of feeding organic copper proteinate,partial or complete replacement of dietary inorganic CuSO4 to gestating sows from four weeks pre-partum and throughout lactation on sow productivity.The results showed that：（1） Supplementation of Bioplex Cu to sow diet could reduce sow body weight loss（P 0.05）.The weaning weight of piglets from sow fed with 30% Bioplex Cu diet significantly increased（P 0.05） compared to the control and 100% Bioplex Cu groups.（2） Dietary Bioplex Cu was helpful to improve digestibility（P 0.05） of Cu and other minerals such as Zn,Fe and Mg and significantly improve dry matter digestibility（P 0.01）.（3） The serum mineral contents of piglets from sows fed with 100% Bioplex Cu diet significantly increased on 14th and 21st day which confirmed that the bioavailability of Cu and other minerals including Zn,Fe and Mn were greatly improved.It was concluded that feeding organic Cu proteinate（Bioplex Cu） to sows could increase bioavailability of dietary copper and other minerals of their piglets,and maintain the serum mineral contents at a high level to sustain optimal growth and healthy status in their later growing stage.
