本试验通过测定猪对真空脱脂大豆（FFSvac）和蒸汽脱脂大豆（FFSstm）的消化率和代谢率，对真空脱脂大豆和蒸汽脱脂大豆进行了比较研究。使用完全随机化的实验设计，具有五个处理（对照饮食、具有FFSvac的饮食、具有FFSstm的饮食、40%FFSvac + 60%对照饮食、40%FFSstm + 60%对照饮食）和四个重复，每个重复是实验单元的动物。用FFSvac或FFSstm替代豆粕，日粮总能量消化率分别降低4%和3%。用FFSvac或FFSstm替代豆粕不影响猪的氮消化代谢。对于FFS，真空处理可消化蛋白质和能量含量分别提高10.4%和4.0%。在饲喂含有FFSvac或FFSstm的日粮的猪中，日粮消化率和能量代谢相似。对于饲喂含有FFSvac或FFSstm的饲料的猪，饲料消化率和氮代谢没有差异。真空加工提高了全脂大豆蛋白质和能量的可消化含量。
An experiment was carried out to evaluate the full-fat soybean (FFS) processed by vacuum (FFSvac) or by steam (FFSstm), by means of digestibility and metabolism of pigs. A completely randomized experimental design was used, with five treatments (control diet, diet with FFSvac, diet with FFSstm, 40% FFSvac + 60% control diet, 40% FFSstm + 60% control diet) and four replications each, being the animal the experimental unit. The digestibility coefficients of gross energy were 4% and 3% lower for the diets with replacement of soybean meal by FFSvac or FFSstm, respectively. The replacement of soybean meal by FFSvac or FFSstm did not influence the digestion and the metabolism of nitrogen of the pigs. For FFS, the content of digestible protein and energy were 10.4 and 4.0% higher with vacuum processing. The diet digestibility and energy metabolism are similar in pigs fed with diets containing FFSvac or FFSstm. For pigs fed with diets containing FFSvac or FFSstm, the diet digestibility and nitrogen metabolism are not different. The vacuum processing improves the digestible contents of protein and energy of full-fat soybean.
