Utilizing rice bran oil in poultry diet as an antioxidant, emulsifier, and alternate source of fatty acids

Abstract

The poultry industry has undergone significant transformations in recent decades, marked by advancements in genetic improvements and nutritional modifications, leading to enhanced weight gain, production, and feed efficiency. Dietary energy, a crucial component influencing production and feed efficiency, is often sourced from oils in poultry feeds. Rice bran oil (RBO), extracted from rice bran, has gained recognition for its health benefits, including its role in alleviating cardiovascular diseases. This article explores the composition of RBO, emphasizing its unique components such as gamma-Oryzanol, Phytosterols, and tocopherols. The antioxidant properties of RBO, attributed to its rich content of natural antioxidants, make it a suitable oil for cooking, frying, and baking. The Unsaponifiable fraction of RBO, particularly gamma-oryzanol, is associated with reducing low-density lipoprotein and total serum cholesterol. The article delves into the chemical refining of crude RBO, discussing both its advantages in terms of color and cloud point and the associated challenges, such as high refining losses. The study investigates the potential use of RBO in poultry nutrition, focusing on its inclusion in broiler diets with emulsifiers. Research suggests that the combination of RBO with specific emulsifiers can significantly improve the growth performance of broilers. Additionally, RBOderived lysolecithin proves to be a viable energy supplement in broiler chicken diets. The effects of RBO supplementation in broiler and layer chickens are explored, encompassing aspects such as growth performance, carcass traits, meat composition, quality, and biochemical profiles. The findings suggest positive outcomes in laying performance and decreased total serum cholesterol in layer chickens with RBO supplementation. The article concludes by emphasizing the growing consumer awareness of the health benefits associated with food consumption and the potential of RBO as a valuable nutritional source in poultry diets. The promising results from studies on RBO supplementation in poultry underscore its potential for enhancing overall performance and nutritional quality in poultry production.
