"Drinking water was treated with 1 mg/L of OxyMer (Oxxion, Eden Prairie, MN), which is a chlorine dioxide solution. It was used here for water sanitation in the same way that municipal water is treated. Furthermore, in efforts to minimize risk of developing and spreading bacterial pneumonia, OxyMer (25 ppm) was also included in the initial feeding of oral electrolytes given to the calves upon arrival as a prophylactic."
