摘要： 为比较不同栽培品种生大豆中抗营养因子对大鼠抗营养影响, 选用(50±2)日龄的W ister大鼠60只, 随机平均分6组, 分别饲喂以吉林小粒6、吉林30、吉林45、吉农7、丰交7607栽培品种生大豆和全脂膨化大豆(对照组)为主要蛋白源的日粮, 30 d解剖大鼠, 肠道分段称重、测量长度并制作组织切片。结果表明:小肠重量、小肠长度、空肠隐窝深度和空肠绒毛长度和隐窝深度比值对照组与试验组差异显著(P<0.05), 各品种生大豆日粮对大鼠肠道影响为吉林小粒6>吉林30>丰交7607>吉林45>吉农7。

Abstract: The objective of this study was to investigate the antinutritional effect of five different China raw soybean cultivars on the intestinal tract in rats. Sixty rats aged (50±2) days were randomly divided into six groups, with each group involved 10 replicates. Test groups were fed on the diets containing raw soybean cuhivars:Jilinxiaoli6, Jilin30, Jilin45, Jinong7, and Fengjiao7607, respectively. Control group diets containing extruded full-fat soybean(EFFS). The whole experiment duration was 30 days, All rats were slaughtered on 30 d. the gut measured length and weight, duodenum central region and jejunum 1/3 and ileum 1/2 were collected to making histological section for light microscope to inspected, respectively. Results showed:The small intestine weight, the small intestine length, the jejunum crypt depth, the jejunum villus height and the jejunum villus height: the jejunum crypt depth of the test groups were significantly (P<0.05) difference compared to the control group. Effect of antinutritional in feeding rats with raw sobean diets is Jilinxiaoli6>Jilin30>Fengjiao7607>Jilin45>Jinong.
