Summary Little difference was found in the teat‐disinfecting efficiency of a hypochlorite or Q.A.C. disinfectant when used at concentrations of 200 ppm. in udder wash waters. The Q.A.C. gave better results than the hypochlorite in summer. With both types of disinfectant micrococci constituted the dominant surviving flora on the teats. No difference was found in the survival of coliaerogenes bacteria. The chlorine strength of the hypochlorite was markedly reduced in the wash water after washing four cows but it was well maintained in a second pail of water containing the cloth used for drying the teats.
