摘　　要：为探讨不同品种大豆胰蛋白酶抑制因子和凝集素含量的差异及其对大鼠生长、养分消化率的影响,试验选用72只Wistar雄性大鼠,按体质量随机分成6组:前5组分别为5个不同品种大豆的试验组,第6组为正常对照组。饲养4周,取粪样和尿样进行消化试验,每周早饲前进行空腹称重。结果显示,吉林45的胰蛋白酶抑制因子和凝集素含量最高,吉农7含量最低。5个试验组之间比较其体增重、饲料利用效率、营养物质消化率及氮平衡、氮存留率差异显著,且显著低于对照组。结果表明,大豆品种不同,其胰蛋白酶抑制因子和凝集素含量存在显著差异,由此对动物生长、饲料利用效率和营养物质消化率的影响程度也存在明显差异。To study the effects of soybean varieties on content of trypsin inhibitor and lectin,and growth,nutrient digestibility in rat.Seventy-two male Wistar rats were randomly divided into six groups and fed on different diets as follows： group 1 to 5 was fed on diets containing one of five soybean varieties respectively,group six was fed on normal diet containing soybean meal and oil.Each group was fed for 4 week,then faeces and urine were collected to determine the nutritional efficiency of diets,and body weight were measured weekly.The results show that trypsin inhibitor and lectin content of Jilin45 was highest,and those of Jinong7 was lowest in five soybean varieties.All measured parameters,including gain in body weight,feed utilization efficiency,nutrient digestibility,nitrogen balance and nitrogen retention,were markedly different among five treatmen groups,and these values were significantly lower than control group.The data demonstrate that soybean varieties could significantly affect trypsin inhibitor and lectin content in soybean,so that there are strikingly differences of growth performance,feed utilization efficiency and nutrient digestibility in animal fed on diets containing different variety soybean.
