It has been found that the nutritional value of soybean capsules is the same as that of the corn when feeding cows. In recent years, conclusion is drawn which it has determinate effect that appropriate soybean capsule are added into the diet of enceinte sows, and it has no negative effect substitution of soybean husks for wheaten bran in feeding enceinte sows. Nevertheless, no report on the use of soybean husks in feeding growth-finishing pigs. It slows down the use of soybean husks in animal breeding.

据报道大豆皮用于奶牛其营养价值等同于玉米，近年来，人们为了使大豆皮更广泛的应用于畜牧生产，在怀孕母猪日粮中适当添加饲喂，得出了有效的结论，并表明用它来替代麸皮饲喂怀孕母猪对其生产无任何负面影响，但是迄今为止，大豆皮是否能用于饲喂生长肥育猪还未见报道，这就妨碍了大豆皮在畜牧生产中的广泛应用。
