Dehydration in calves

A new effervescent tablet to treat dehydration in calves

Our effervescent tablet Efferfizz is a fast-dissolving calf supplement designed to solve the urgent need for rehydration in situations where calves lose a lot of water and electrolytes. Disturbances like diarrhea can cause acidosis in calves, their main problem. The effervescent tablet is meant to treat light stages of dehydration.
