Research Progress on Nutritional Value of Olive By-Products and Their Application in Pig Production
Olive by-products are the products obtained after olive oil extraction,which contain rich nutrients such as unsaturated fatty acids,dietary fiber and crude protein,as well as natural bioactive substances such as phenols,flavonoids,triterpenes and vitamins.Olive by-products as pig feed raw materials can improve the growth performance of pigs,enhance the immune and antioxidant capacity of the body,and improve the quali-ty of meat products.Olive by-products are increasingly used in pig diets,but their application prospects are still to be further explored.In this paper,the nutritional components and active substances of olive by-products and their feeding value to pigs were reviewed,aiming to provide reference for the application of olive by-products in pig diets.[Chinese Journal of Animal Nutrition,2024,36(7):4116-4125]
