Abstract:
Forty Holstein cows in mid-lactation were utilized to evaluate the effects of water oxygenation
on milk production, milk composition, and somatic cell count. Cows were fed a total mixed ration
consisting of 25% alfalfa, 25% corn silage, and 50% corn-soy concentrate on a dry matter basis.
Treatments included a 7-day preliminary period followed by two 28-day periods in which the
treatments were reversed.
Water consumption, milk production, milk composition, and somatic cell count were not
different between treatments. Cows receiving oxygenated water were more docile and easily managed
than control cows. Ozone introduced into water forms hydrogen peroxide, nitrous oxide, and increases
the redox potential of the water.
