鸡日粮中不同来源油脂的营养价值特性及其混合应用的研究进展OA

Fats and oils are important energy sources in poultry diets,as they not only effectively increase dietary energy density but also play critical roles in regulating nutrient absorption,immune responses,antioxidant capacity,and reproductive performance.Marked differ-ences in fatty acid composition among oil sources result in substantial variation in their nutritional value and physiological functions.This re-view systematically summarizes recent research on commonly used dietary oils in chicken nutrition,including soybean oil,rapeseed oil,palm oil,linseed oil,cottonseed oil,rice bran oil,animal fats,as well as emerging lipid sources such as coconut oil and black soldier fly larvae oil,with emphasis on their nutritional characteristics and physiological functions.In addition,the current status of applying blended oils in poultry production and the major challenges associated with their use are also discussed.
