摘　　要：试验旨在筛选出膨化大豆在生长育肥猪日粮中替代豆粕的最适添加量。试验选用胎次相近、健康的"杜×长×大"三元猪80头[公母各半,平均体重为(35.83±5.07)kg],按照体重相近、公母各半的原则随机分为4个试验组,每组5个重复,每个重复4头猪。对照组饲喂玉米-豆粕型基础日粮,试验组日粮分别用10%、30%和50%的膨化大豆等量替代对照组日粮中的豆粕和豆油,研究日粮中使用膨化大豆替代豆粕对颗粒饲料加工质量的影响及对生长育肥猪生长性能的影响。试验结果表明:与对照组相比,日粮中膨化大豆等量替代豆粕+豆油可提高生长猪的生长性能,但对颗粒饲料加工质量和育肥猪的生长性能均无显著影响。生长猪可通过日粮中添加膨化大豆替代豆粕来提高其生长性能。The aim of this study was to scxeen out the optimum amount of soybean meal in tire diet of piglets. There were ＂Duroc x Landrace x Large＂ eighty Three-crossbred pigs of male and female [aver- age weight of （35.83＋5.07） kg]. According to the similarity of body weight＋ the principles of male and female were randomly divided into four test groups, 5 replicates per group, 4 replicates pet＂ replicate. The control group was fed with corn-soybean meal basal diet, and the diets of the test group were re- placed the soybean meal and soybean oil with ｜0%. 30% and 50% puffed soybeans in the eontl＇o[ group. The effects of extruded soybean substituted fin＂ soybean meal on feed processing quality and growth performance of growing fattening pigs. The results showed that compared wilh the control group, the extruded soybean had no significant effect on the quality of pelleted feed. The growth pertor- mance of the growing pigs could be improved, but the increasing of growth performance of the pig was not significant. The growth performance of growing pig increased hy adding extruded soybeans replac- ing soybean meal.
