Research progress in application of microecological preparation in sheep production
Under the background of banning antibiotics in feed and reducing antibiotics in veterinary drugs,finding green,safe,and efficient alternatives to feed antibiotics is a hot issue in sheep farming at present.Microecological preparation is a kind of non-toxic,residue-free,non-resistant and green biologically active preparation,which has the functions of regulating the microecological balance of the intestinal tract,improving the intestinal barrier,improving the immunity,enhancing the antioxidant function,and facilitating the digestion and absorption of nutrients.It is one of the ideal alternatives to antibiotics,and it is widely used in the production of livestock and poultry.In recent years,the research and application of microecological agents in sheep production have also made great progress,and have been proved to play a positive role in the growth performance,meat quality,immune function,and antioxidant function of sheep.In this paper,the mechanism of micro-ecological agents and their application in sheep production are discussed comprehensively,aiming to provide a reference for the micro-ecological agents rational application and development in sheep production,and to further promote the efficient and healthy development of sheep farming.
