【摘要】 本试验旨在研究添喂大豆蛋白酶解物对早期断乳仔猪免疫组织、器官及血清白介素-2水平的影响。将12头体重相近的三元杂交仔公猪分为对照组(28日龄断乳,饲喂早期断乳仔猪料)和处理组(21日龄断乳,在饲喂早期断乳仔猪料的基础上,每头每天添喂2 g大豆蛋白酶解物,连续10 d)。结果表明:与对照组仔猪相比,添喂大豆蛋白酶解物的仔猪胸腺的绝对和相对质量分别增高105.90%(P<0.01)和96.30%(P<0.01);脾脏的绝对和相对质量分别增高43.78%(P<0.01)和27.52%(P<0.05);腹股沟淋巴结的绝对和相对质量分别增高28.89%(P<0.05)和15.22%(P>0.05);血清白介素-2水平提高8.73%(P>0.05);脾脏的中央动脉周围淋巴鞘面积增大6.47%(P>0.05);回肠派伊尔结(Peyer′s patches)总个数增加4个(P>0.05),派伊尔结总面积减小0.700 3 mm2(P>0.05)。更多还原

【Abstract】 This experiment was conducted to investigate the effect of soybean protein hydrolysate on the immunity tissues and organs and the level of serum interleukin-2 in early weaning piglet. Twelve piglets similar in weight were divided into two groups:a control group (in which the piglets were weaned at 28 days old,and fed on the early weaning feed) and a treatment group (in which the piglets were weaned at 21 days old,and fed on the early weaning feed plus (2 g) soybean protein hydrolysate daily for 10 days). The results indicated that compared with the control,feeding soybean protein hydrolysate enhanced the absolute and relative weight of thymus by 105.90% (P<0.01) and 96.30% (P<0.01) respectively,absolute and relative weight of spleen by 43.78% (P<0.01) and 27.52% (P<0.05) respectively,absolute and relative weight of groin lymph node by 28.89%(P<0.05) and 15.22% (P>0.05) respectively,and enhanced the level of serum interluekin-2 in early weaning piglet by 8.73% (P>0.05), and increased the area of spleen′s lymph theca around center artery by 6.47% (P>0.05), and increased the total number of ileum Peyer′s patches by four,but decreased the total area of ileum Peyer′s patches by (0.700 3 mm~2) (P>0.05).更多还原
