Feeding Value of Walnut Green Husk and Its Application in Animal Production
Walnut green husk is the main by-product of walnut processing.The production of walnut green husk is huge in China,but the utilization rate is low,and most of it is discarded as waste.Studies have shown that walnut green husk is rich in amino acids,dietary fiber,minerals,as well as naphthoquinone,flavonoids,polyphenols,polysaccharides and other bioactive components,Therefore,the development and utilization of walnut green husk as feed raw materials or feed additives for livestock and poultry can not only turn waste into treasure,but also reduce feed costs,reduce environmental pollution,improve the growth performance of live-stock and poultry,enhance the body's immune and antioxidant capacity,and improve the quality of livestock and poultry products.In this paper,the nutritional value and bioactive components of walnut green husk and their application in animal production were reviewed,in order to provide reference for the scientific develop-ment and utilization of walnut green husk.[Chinese Journal of Animal Nutrition,2024,36(12):7647-7657]
