The Valorization and Potential Applications of Orange Byproducts and Waste in Poultry Feeding: A Review

Abstract

Some chemicals have been utilized as a feed additive and growth stimulator to boost poultry performance in recent decades. Cereals have been one of the most extensively utilized feed in the rearing period of broiler chickens but due to their highly price it can present an economic consequence and some limitations of their use, alternatives such as orange byproducts have been recommended. In the second point there is a large utilization of growth stimulants during the rearing period of broilers, but due to the adverse consequences of antibiotic resistance and the limitations of their use, alternatives such as probiotics, prebiotics, plant essential oils, essences and by-products have been recommended. Orange waste can be found in abundance in some parts of the world. Aldehydes, esters, terpenes, alcohols, ketones, carotenoids, nobiletin, pectin and bioflavonoids such as hesperidin and naringenin are among the volatile substances found in orange waste. The practical applications of orange by-products and pomace in chicken feeding are presented in this review paper. This review presented the effects of orange waste and by-products on chicken performance and carcass components.
