Abstract: This review aims to identify the effects of the flavonoid dihydroquercetin (DHQ) on performance, physiological parameters and biochemical indicators of the body, as well as its application as an adaptogen to reduce stress and an improvement of production quality in pigs and poultry. It was concluded that DHQ successfully affects carbohydrate and fat metabolism, in direction improvements of the physiological parameters. DHQ has the ability to reduce the content of cholesterol in the blood by lowering the levels of genes responsible for its synthesis. DHQ prevents the development of lipid peroxidation and increases the body's antioxidant defense. Dihydroquercetin has proven cardiovascular protective and antiatherosclerotic effects and can be used effectively for treatment and prevention. DHQ has a hepatoprotective effect as well, expressed in improving liver lipid metabolism, increasing the activity of antioxidant enzymes, while reducing liver lesions and necrotic processes. The effects of DHQ are shown very well in highly productive animals as stress reducer and as an improver of the product quality from pigs and poultry. Supplementation of the basal diet with phytonutrients such as DHQ results in а reduced accumulation of primary and secondary products of lipid oxidation in meat during storage and is a promising strategy for increasing the oxidative stability of lean pork and fat. The listed positive effects of dihydroquercetin indicate that it has the potential for successful application in pig farming and future research. Аs a feed additive in monogastric nutrition, DHQ has a potential to counteract mycotoxin-induced intestinal toxicity.
