摘　　要：为比较2个不同栽培品种生大豆中抗营养因子对大鼠的影响,以50±2日龄Wister大鼠为实验动物,分别饲喂以吉林30、吉农7品种生大豆和膨化大豆粕(对照组)为主要蛋白源的日粮,测定生长性能,第30天解剖大鼠,颈静脉采血检测血液生理生化指标,内脏器官称重,制作肠道组织切片。结果表明:吉林30日粮组大鼠增重、料肉比、胰腺重量、小肠长度、小肠重量、空肠绒毛长度、空肠隐窝深度、白细胞、血浆尿素氮、谷丙转氨酶和总胆红质与对照组大鼠差异显著(P<0.05),吉林30日粮组大鼠胰腺重量、空肠隐窝深度(JCD)比吉农7日粮组大鼠高29.1%、14.4%(p<0.05)。吉林30做日粮对大鼠抗营养的影响大于吉农7。The objective of this study was to investigate the antinutritional effect of two different soybean cultivars in rats. Thirty rats aged 50±2 days were randomly divided into three groups, with each group involved 10 replicates. Test groups were fed on the diets containing raw soybean cuhivar Jilin 30 and Jinong 7, respectively. Control group diets containing ex- truded soybean meal（ESM）. The whole experiment duration was 30 days, and individual rat weights and feed intakes were recorded weekly. All rats were slaughtered on the 30tb day, the rats were collected blood by jugular vein before dissected, the plasma physiological and biochemistry parameters were detected, pancreas, liver, speend, kidney and stomach were collected quickly for weighting, duodenum central region and jejunuml/3 and ileuml/2 were collected to making histological section for light microscope to inspected, respectively. Results showed the gain weight, feed intake, the pancreas weight, small intestine length, small intestine weight, the jejunum villus height（JVH） , the jejunum crypt depth （JCD） , white blood （cell） count （WBC） , plasma urea nitrogen （ PUN ） , glutamate-pyruvate transaminase （GPT） and total bilirubin （TBIL） of the rats fed on the diets containing Jilin 30 raw soybean were significantly different compared to the control group （P 〈 0.05）. The pancreas weight and jejunum villus height（JVH） of rats fed on the diets containing Jilin 30 raw soybean were 29.1% and 14.4% （P 〈0.05） higher than those fed on Jinong 7. Results suggest the antinutritional effect of Jilin 30 in feeding rats is higher than that of Jinong 7.
