Sixteen Holstein dairy cows were studied to evaluate mammary gland cells? tight junction permeability (indicated by plasma lactose levels) from cows producing stable or unstable milk to ethanol at 72 °GL concentration. Rectal temperature, respiratory rate and milk parameters were also compared and weather conditions (temperature?humidity index) monitored. Temperature?humidity index did not vary for cows producing stable or unstable milk, so there were no differences in physiological traits. Cows producing unstable milk presented elevated tight junctions? permeability, probably due to higher days in milk. The odds of cows producing unstable milk (clots formation when mixed with ethanol below or equal 72 °GL) increases according to elevations in days in milk and tight junction permeability.  aBovino  aEtanol  aGado Leiteiro  aLeite  aPermeabilidade  aProdução Leiteira  aEthanol test  aMilk stability  aTight junctions’ permeability1 aFISCHER, V.1 aDALTRO, D.
