Abstract

An ozone concentration influenced depressively a milk production of dairy cows in warm season only (-0.054 kg milk/head/day per 1 µg O3/m3). In cold season was influenced on milk production positively (+0.031 kg milk). Negative influence on milk production of dairy cows have had firstly a photolysis fouling (NOx) that have acted together with ozone.
