Composition of lick blocks and their application in ruminant production
Lick blocks are a type of block feed,made from a scientifically formulated and processed mixture of nutrients(mineral elements,vitamins,etc.)that ruminants require daily.They possess bioactivities such as enhancing the body's antioxidant levels,immune capabilities,dry matter intake,feed digestibility,and reproductive performance.Currently,lick blocks have been widely applied in ruminant animal production and can significantly improve the health status of ruminants.The article reviews the types and ingredients of lick blocks,raw material formulations,processing techniques,and their impacts on the growth performance,production performance,and antioxidant levels of ruminants.It aims to provide a reference for the application and development of lick blocks in ruminant animal production.
