Providing water that is free of toxin producing biofilm is very important for animal health. If there is no biofilm in pipes and troughs, then, the animals won't be fighting toxins or toxin producing bacteria. The video below shows two types of water provided to dairy cows. The first has no biofilm, the second and third trough are contaminated by toxic biofilm.
Pruex works with farmers to help eliminate biofilm from the water they give their animals.
