THE EFFECTS OF ANTIOXIDANT DIETARY SUPPLEMENTATION ON ANIMAL PRODUCT QUALITY

Abstract: 

Published data demonstrate that hesperetin and naringenin, widely distributed citrus flavonoids, have positive effects on human health. Flavonoids possess intense antioxidant properties. Hesperetin and naringenin in particular, have been proposed as dietary supplements in animal production, especially for citrus-producing countries, as the byproducts of citrus fruit industry are an excellent source of these flavonoids. Functional foods are in the forefront of consumers and food industry interest and constant efforts aim to improve the quality and properties of animal products, minimizing the negative implications for human health after animal food consumption.

Here we propose to evaluate the effects of hesperetin and naringenin dietary supplementation on the properties of animal products. We will study their effects on qualitative and quantitative characteristics of meat, milk and eggs of broilers and lambs, ewes and hens respectively. We will assess different feed concentrations of the two flavonoids and their effects will be compared to those of vitamin E, a widely used antioxidant. Our data will determine the dietary value of hesperetin and naringenin and the specific conditions for their possible inclusion in animal feed. In addition,we will study the metabolism of hesperetin and naringenin included in the animal feed by detecting their presence or the presence of their metabolites in plasma, muscle, milk and eggs. Furthermore,we will study the possible molecular mechanism of their function by assessing their effect on the expression of genes involved in lipid metabolism.

This study will provide new knowledge on the metabolism of hesperetin and naringenin included in chicken and sheep feed, their effect on animal products quality and the possible underlying molecular mechanism. Ultimately,our data will determine the potential of hesperetin and naringenin as cost-effective alternative antioxidant dietary supplements, for better and cheaper animal products.
