2, intestinal flora-promoting the growth of intestinal beneficial bacteria (such as Lactobacillus, Bifidobacterium), can reduce the number of harmful bacteria, thereby reducing the competition for nutrition. Healthy intestinal flora can also increase the production of butyrate, which is the energy source of intestinal mucosal cells and has antibacterial activity.
3. Feed intake-Studies have shown that when the feed intake increases, various negative effects on the intestines of weaned piglets will decrease. Higher feed intake can lengthen intestinal villi, improve nutrient absorption and reduce the number of pathogenic bacteria (such as Escherichia coli).
