| Research Abstract |
It is desirable to consider a new strategy to prevent rumen acidosis, which is cased when ruminants are fed high-concentrate diets, because the dose of antibiotics and ionophores may cause the risk of residual antibiotics in animal products. Therefore, to prevent the overgrowth of the bacterium causing rumen acidosis (Streptococcus bovis), I identified a chemical signaling molecule to control the growth, which may be related to the change in the expression of several proteins, in S. bovis. This result may contribute to the development of a new strategy for the control of S. bovis overgrowth and the prevention of rumen acidosis.
