本研究旨在验证在断奶仔猪日粮中添加刺五加提取物(AS)可增强仔猪免疫功能的假设。将60头21日龄断奶仔猪随机分成3组，每组20头，分别在玉米和豆粕基础日粮中添加0或1g/kg的AS提取物或0.2g/kg的粘菌素(一种抗生素)。分别于开始添加后第7、14、28天测定白细胞总数、分类计数、外周血淋巴细胞增殖活性、血清免疫球蛋白(Ig)、细胞因子水平及脾指数。砷浸出物减少(p<0.05)。
This study was conducted to test the hypothesis that dietary supplementation with an herbal extract of Acanthopanax senticosus (AS) enhances the immune response in weaned piglets. Sixty piglets weaned at 21 days of age were randomly assigned to 3 treatment groups representing the addition of 0 or 1 g/kg of the AS extract or 0.2 g/kg of colistin (an antibiotic) to maize- and soybean meal-based diets (n = 20 per group). On days 7, 14 and 28 after initiation of the addition, total and differential counts of leucocytes, proliferating activity of peripheral lymphocytes, serum levels of immunoglobulins (Ig) and cytokines and the spleen index were determined. The AS extract decreased (p
