Effect of replacing some soybean meal with feed yeast on growth performance, serum biochemical indexes, intestinal microbiota, and nutrient digestion and absorption of 20-40kg growing pigs

This experiment was conducted to explore whether it is possible to use feed yeast powder to replace part of soybean meal by using feed yeast powder on a diet on the growth performance, serum biochemical indexes and intestinal microbiota, and nutrient digestion and absorption of 20-40kg growing pigs, so as to reduce the use of soybean meal and improve the economic efficiency and provide some scientific basis for pig breeding.
