Influence of low or high density corn and soybean meal-based diets and protease supplementation on growth performance, apparent digestibility, blood characteristics and noxious gas emission of finishing pigs

The stress related hormones were also reduced in pigs fed protease supplemented diets. In addition to tendency in weight gain, feed efficiency was improved in pigs fed high density diets than low density diets.
