Research Progress on Effects of Malondialdehyde on Aquatic Feed and Aquatic Animals'Health
Malondialdehyde(MDA)is a significant carbonyl compound that is formed during non-enzymatic oxidation reactions of lipids and sugars,showing high levels of biotoxicity.The main risks associated with MDA in aquaculture include the disruption of essential nutrient structures in feed,such as proteins,lipids,and vitamins,as well as negative effects on animal health.These effects can lead to reduced production perform-ance,compromised intestinal mucosal barrier,liver toxicity,decreased antioxidant capacity,and increased in-flammation.This review specifically examined the production of MDA in feed,the mechanisms that influence the structure and function of key nutrients in feed,and the overall health of aquatic animals.The primary goal is to establish a theoretical basis for preventing feed oxidation and ensuring feed safety.[Chinese Journal of Animal Nutrition,2024,36(9):5497-5509]
