Hygienic conditions of milk production on ten farms of the Pozorice Cooperative Farm near Brno were investigated by means of a modified reductase test in 1989. Total counts of microorganisms and the group of coliform, thermophilic and psychrotrophic bacteria were investigated simultaneously. The correlation coefficients ranging from 0.587 to 0.973 were determined for the total counts of microorganisms and the Lakto-la-test in the quarters of the year. The values of the coefficients of correlation between the total counts of microorganisms and the number of coliform bacteria were significant (r=0.615 to 0.837). On the other hand, the values of the coefficients of correlation between the total counts of microorganisms and the counts of psychrotrophic microorganisms ranged from 0.234 to 0.749. The Lakto-la-test helps to find out and to reveal shortcomings of the hygiene of milk production; if it is used systematically, it contributes efficiently to an increase in the microbiological quality of milk.
