【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。
[Abstract]:The aim of the experiment was to screen out the optimum addition of expanded soybean to the diet of growing and fattening pigs instead of soybean meal. 80 healthy "du 脳 long 脳 big" three Yuan pigs [half male and half female, average body weight was 35.83 卤5.07)kg] were randomly divided into 4 test groups according to the principle of similar body weight and half male and female. The control group was fed with corn-soybean meal basal diet, and the control group was fed with 10% and 50% extruded soybean instead of soybean meal and soybean oil, respectively. The effects of using expanded soybean instead of soybean meal on the processing quality of pellet feed and the growth performance of growing and fattening pigs were studied. The results showed that: compared with the control group, the same amount of expanded soybean in the diet could improve the growth performance of the growing pigs, but had no significant effect on the quality of the pellet feed processing and the growth performance of the fattening pigs. Growing pigs can improve their growth performance by adding expanded soybean instead of soybean meal.
