Research progress of rumen protected amino acids on application of ruminants production
Ruminants have a unique digestive process in their rumen,where the direct addition of untreated amino acids in feed is mostly degraded by rumen microorganisms,which not only leads to the waste of amino acids but also increases environmental pollution due to nitrogen emissions.Therefore,it is necessary to protect amino acids from ruminal degradation.The main technologies for ruminal protection currently include encapsulation,chemical,and biological techniques.Methionine and lysine are the main limiting amino acids for ruminants.Adding ruminally protected lysine(RPL)and ruminally protected methionine(RPM)to the feed can improve the growth performance of ruminants,promote the digestion and absorption of feed nutrients,and improve the quality of ruminant products.The article reviews the nutrition of amino acids in ruminants,the processing technology of ruminally protected amino acids,and the production application of ruminally protected amino acids in ruminants,aiming to provide a reference for the research on amino acid nutrition in ruminants.
