本试验旨在研究饲粮中添加多血碱对生长猪血清代谢物的影响。试验选用240头6周龄的约克郡长猪，随机分为3个饲粮处理，每个处理8个重复，每个重复10头仔猪。饲粮处理为：基础饲粮（BD）对照组、血碱组（BD + 0.04 g/kg）和抗生素组（BD + 0.2 g/kg粘菌素）。在开始处理后第7天和第14天，测定体重、平均日增重、平均日增重、饲料效率（F/G）和血清氨基酸水平。与对照组相比，饲粮中添加血根碱和抗生素可提高日增重、ADFI和体重（P < 0.05）。结果表明，与粘菌素组和（或）对照组相比，血根碱组血清中Gly、Ile、Lys、Met、Arg、Ala和Thr等氨基酸含量显著升高（P < 0.05）。上述结果表明，饲粮中添加血根碱对生长猪血清中一些必需和非必需氨基酸浓度有有益影响，从而提高生长猪的生长性能。
This study was conducted to determine the effect of dietary sanguinarine supplementation on serum metabolites in growing pigs. A total of 240 (Yorkshire ' [Duroc ' Landrace]) pigs at 6 wk of age were randomly allotted to 3 dietary treatments, with 8 replicates per treatment and 10 piglets per replicate. The dietary treatments were as follows: the basal diet (BD) control group, the sanguinarine group (BD + 0.04 g/kg), and the antibiotic group (BD + 0.2 g/kg colistin). On d 7 and 14 after initiation of the treatment, BW, ADG, ADFI, feed efficiency (F/G), and serum levels of amino acids were measured. Dietary sanguinarine and antibiotic supplementation increased ADG, ADFI, and BW compared with the control group (P < 0.05). The data showed that the serum contents of amino acids, such as Gly, Ile, Lys, Met, Arg, Ala, and Thr, increased (P < 0.05) in the sanguinarine group compared with those in the colistin group and/or control group. These findings indicate a beneficial effect of dietary sanguinarine supplementation on the serum concentrations of some essential and nonessential amino acids, which improves growth performance of growing pigs.
