Clean water for clean milk

The UK Mastitis Control Plan clearly states that mains water is preferred to on farm sources due to lower bacterial pressure on the animals that drink it from their troughs, bowls or vessels. But cows drink large volumes of water. But do they drink as much as they could do? Is their milk yield potential under achieved due to putrid tasting water? Does water infected by bad bacteria challenge their immune system and ultimately cause infections?

Helping farmers clean their water sources is an area Pruex specialise in.
