摘  要：
选择34±1日龄断奶、体重8 7±0 8kg的二元杂交(长白×大白)阉公猪30头进行试验,研究饲粮添加有机甘氨酸铜相对于无机硫酸铜对断奶仔猪生长性能、血液生理生化指标和血浆及组织中铜含量的影响。试猪按完全随机区组设计,依体重和窝别随机分为3个处理组,分别饲喂添加15(n=6)和250mg/kg铜源于硫酸铜(n=12)及250mg/kg铜源于甘氨酸铜(n=12)的饲粮。猪只个体饲养于代谢室(22 5℃左右)内无元素污染的玻璃缸代谢笼中。正式试验期28d,猪只自由采食与饮用自来水。3个处理组间,猪生长速率、采食量、饲料转化效率、血红蛋白浓度、血细胞压积、血浆生化指标(总胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、甘油三脂和尿素氮)及血浆、胰、肾和脾中铜含量均无明显差异(P>0 10);与添加15mg/kg铜源于硫酸铜的对照组相比,添加250mg/kg铜分别源于硫酸铜和甘氨酸铜的两个处理组均明显提高了断奶仔猪脑、肝及心肌中的铜含量(P<0 05),而两个高铜水平的铜源处理组间无明显差异(P>0 60)。本次研究结果表明,有机甘氨酸铜与无机硫酸铜对断奶仔猪同等有效。

摘  要：
An experiment was conducted with 30 crossbred (Landrace×Large White) weanling barrows averaging 8.7±0.8 kg BW and 34±1 d of age to investigate the effect of dietary Cu as Cu-glycine on growth,blood physiological and biochemical traits,and Cu contents in plasma and tissues.Pigs were randomly allotted by body weight and litter to one of three treatments in a randomized complete block design,and fed basal corn-soybean meal-whey diets supplemented with 15 (n=6) or 250 mg/kg Cu as Cu sulfate (n=12) or 250 mg/kg Cu as Cu-glycine (n=12),respectively.Pigs were individually kept in fiber glass metabolism crates in a metabolism room (around 22.5 ℃) for the duration of the 28 d experiment.Pigs were allowed free choice continuous access to feeds and tap water.No Cu treatment differences (P>0.10) were observed in growth rate,feed intake,feed conversion ratio,blood hemoglobin and hematocrit,and plasma biochemical traits (Cholesterol,HDL-C,LDL-C,triglyceride,and urinary nitrogen,)or Cu contents in plasma,pancreas,kidney and spleen.However,pigs fed diets with 250 mg/kg Cu added from either Cu sulfate or Cu-glycine had increased (P<0.05) Cu contents in brain,liver and heart compared to pigs fed the diet with 15 mg/kg Cu added from Cu sulfate.No differences (P>0.60) were detected between the two Cu sources.These results from this study indicate that Cu from both Cu-glycine and Cu sulfate was equally effective to weanling pigs.
