| 摘 要： | 将20头3周龄断奶的DLY仔猪随机分成4组,断奶后第1周分别饲喂以膨化全脂大豆、膨化豆粕、膨化去皮豆粕和大豆浓缩蛋白为主要蛋白源的全价日粮,第2周开始,所有仔猪均饲喂同一日粮10d,以考察不同大豆蛋白饲料的营养效应。结果表明:4种大豆蛋白饲料对仔猪断奶后第1周生产性能无明显影响,但膨化豆粕能显著改善试验后期及全期仔猪生产性能。第1周膨化豆粕日粮蛋白质利用率显著高于膨化全脂大豆日粮和膨化去皮豆粕日粮(P<0.05)。膨化豆粕较其他大豆蛋白饲料更有利于仔猪断奶早期的氮代谢和提高机体的的免疫机能。综合本试验结果表明,膨化豆粕是3周龄断奶仔猪断奶早期饲粮的适宜大豆蛋白源。

| Abstract: | This study was intended to investigate the nutritional effects of different soybean products.20 DLY piglets weaned at the age of 3 weeks were randomly allocated into four dietary treatments with five replicates per treatment and one piglet per replicate.In the first week,each treatment was fed a diet containing extruded full-fat soybean(EFS),extruded soybean meal(ESM),extruded dehulled soybean meal(EDSM) or soybean protein concentrate(SPC) respectively at the same nutritional level.And then,piglets of all treatments were fed the same diet for 10 days.The result showed that the piglets fed the diet contained ESM had significant superiority in improving the ADFI,ADG,and reducing F/G in the second and whole feeding period.In the first week,the protein availability of the diet contained ESM was significantly higher than those of the diets contained EFS and EDSM(P < 0.05).The biochemical indexes of serum showed that ESM was beneficial for early-weaned piglets to improve the nitrogen metabolism and immune function.The results indicated that ESM was the best soybean protein source for early-weaned piglets. |
