Microorganisms inhabit the gastrointestinal tract of ruminants and regulate body metabolism by maintaining intestinal health. The state health is influenced not only macro-level factors optimal development physiological structure integrity but also delicate equilibrium between flora immune status at micro-level. Abrupt weaning in young causes incomplete resulting an unstable unformed microbiota. induced damages to microecological homeostasis tract, infections diseases, such as diarrhea. Recently, nutritional functional yeast culture has been researched tackle these problems. Herein, we summarized current known interactions microorganisms ruminants, then discussed regulatory effects using a feed supplement. Yeast preparation that contains yeast, enriched with metabolites other nutrient-active components, including β-glucan, mannan, digestive enzymes, amino acids, minerals, vitamins, some unknown growth factors. It stimulates proliferation mucosal epithelial cells reproduction providing special nutrient substrates support function. Additionally, β-glucan mannan effectively stimulate immunity, promote response, activate macrophages, increase acid phosphatase levels, thereby improving body’s resistance several disease. incorporation into ruminants’ diet significantly alleviated damage caused stress which acts effective strategy balance flora, tissue, establishment system. Our review provides theoretical basis for application ruminants.
