Effects of cooling on the THI index, endotoxin, and QS signaling molecules. *: significant (P < 0.05); **: highly significant (P < 0.01); ***: extremely significant (P < 0.001). A Averaged daily THI values in the two treatment barns throughout the period for data and sample collection, B LPS endotoxin concentration in the rumen fluid. C LPS endotoxin concentration in the blood, D LPS endotoxin concentration in the urine, E estimated LPS endotoxin excretion through the urine, F 3-OXO-C6-HSL belonging to the AHLs. G AI-2
