Research Progress on the Regulation of Rumen Fermentation by Different Surfactants in Ruminants
Surfactant is a novel feed additive for ruminants,according to the molecular structure of the surfactant,it can be divided into anionic,cationic,zwitterionic and non-ionic surfactants.The action mechanism is through changing of rumen microbial population to increase the secretion and activity of endogenous enzyme in the rumen,or promote the interaction between enzymes and sub-strates,and change the ruminal fermentation mode and improve the ability of degrade roughage of rumen microorganisms,in order to improve ruminant production performance.T he authors re-viewed the classification of surfactants and the effects of several common surfactants on regulation of rumen fermentation including nonionic(Tween,alkyl polyglycosides and tea saponin),zwitteri-onic(betaine and soy phosphorlipids)and anionic(sodium dodecyl benzene sulfonate and aerosol-OT).Introducing the impact of rumen microbial population,endogenous enzyme activity,fermen-tation product w hen adding different ionic surfactants to the diet,it provides reference for the de-velopment of new surfactants and the rational use of surfactants in ruminant diets.
