Impact of fermented feed of soybean hulls and rapeseed cake on immunity, antioxidant capacity, and gut microbiota in Chahua chicken

The Effects of Unconventional Feed Fermentation on Intestinal Oxidative Stress in Animals

“…Enzymes and metabolites in fermented feed can promote the decomposition and release of nutrients, improve nutrient availability, and thus enhance the ability of animals to digest and absorb nutrients. In addition, fermented feed is rich in antioxidants, which can scavenge free radicals, reduce the impact of oxidative stress on the intestinal barrier and absorption function, protect the health of intestinal mucosal cells and tissues, and maintain normal cell and tissue function [ 132 ]. The intestinal mucosa, as the largest interface between the body and the external environment, is easily disturbed by factors such as pathogenic microorganisms, pro-inflammatory factors, and antigens.…”

“…The effect of unconventional fermented feed on intestinal microbiota is significant. Its functions are mainly reflected in regulating the structure and composition of microflora, increasing the number of beneficial microorganisms, promoting the diversity of microflora, and improving the metabolic function of microflora [ 132 ]. Through these effects, fermented feed can maintain the balance and stability of the intestinal flora, promote the growth and reproduction of beneficial bacteria, and inhibit the reproduction of harmful bacteria, thereby improving the intestinal health of animals.…”

“…Immunomodulatory effects can promote the production and activation of immune cells, enhance the body’s immune response, and reduce the risk of animal disease [ 132 ]. Secondly, the anti-inflammatory components in fermented feed can inhibit the occurrence of inflammatory reactions, reduce the burden on the immune system, and protect the body’s tissues from damage.…”
