Zorbifresh™ Active can be used as a part of a regular process to keep calf pens clean and disease free, but is also highly effective in larger doses post a bacterial outbreak.

The two major diseases leading to calf mortality are scours and pneumonia. Pneumonia is a respiratory disease, so reducing ammonia in the air surrounding calves is part of lessening the risk associated with calf housing.

ZorbiFresh™ Active was tested using the industry standard laboratory efficacy evaluation test. ZorbiFresh™ Active is 100% effective against Staph. aureus and E. coli after 1 hour exposure. Organic soiling of the bedding reduced the efficacy of ZorbiFresh™ Active after 1 hour exposure but 100% kill was achieved after 24 hours exposure.

Why use Zorbifreshâ„¢ Active?

Respiratory diseases of dairy calves can be extremely harmful for the longevity of young, housed calves, they can be caused by bacterial agents such as ammonia. Other respiratory diseases in your calves may include calf diphtheria, calf coughs and lungworm. 

Affected calves might cough and could be either bright and well with minimal discharge from their nose/eyes or they could be very sick. Early diagnosis, treatment and prevention is really important as once the calves are sick the damage to the lungs can be permanent, meaning the calves will continue to be susceptible to respiratory disease as they grow. 

By using ZorbiFresh™ Active in your calving pens to avoid ammonia growth and prevent damp and smelly bedding, you will help eliminate bacteria as soon as it is laid.

How to prepare the Ideal Calf Pen
