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

Abstract

Unconventional feed, which is abundant in China, contains anti-nutritional factors and toxins; however, these can be greatly reduced with microbial fermentation, thus improving the nutrient content of the feed, enhancing animal appetites, and ultimately significantly improving the intestinal health and growth performance of animals. When oxidative stress occurs, fermented feed can effectively reduce the damage caused by stress to the gastrointestinal tract, accelerate the removal of gastrointestinal abnormalities, improve the ability to resist intestinal stress, and ensure the efficient production of animals. This review introduces the application of unconventional fermented feed in animal production, and expounds upon the function of unconventional fermented feed in animals with oxidative stress symptoms, so as to provide a theoretical reference for the development and application of unconventional fermented feed in antioxidative stress reduction.

Suitable Cottonseed Protein Concentrate Supplementation in Common Carp (Cyprinus carpio) Serves as an Effective Strategy for Fish Meal Sparing Based on Improvement in Intestinal Antioxidant Capacity, Barrier and Microbiota Composition

“…For aquatic animals, the destruction of oxidative homeostasis will result in oxidative stress and further impairment of tissue function [54]. Particularly within the intestine, its antioxidant capacity serves to ensure intestinal structural integrity and functional stability [55], which are affected by the breeding conditions represented by the composition of feed materials [56,57]. To date, there has been ample evidence that high levels of plant-based protein sources replacing fish meal cause oxidative damage [58,59].…”
