Vecoxan® is used for the prevention of coccidiosis in calves and lambs. For more information on Vecoxan, including how and why to use it, watch the video below.
To prevent disease and reduce the impact of sub-clinical disease, treatment using Vecoxan® should be administered close to the time when exposure to coccidiosis is known to occur.
Exposure is required for protective immunity to develop. Therefore, treatments should be administered 8-15 days after moving to a high-risk environment or if historical data is available, approximately one week before the expected outbreak.
How to use Vecoxan – ‘No one size fits all’

There is ‘no one size fits’ all for treating coccidiosis on farms. It is important to speak to your vet about the best approach for your farm.
Historical treatment
Treat whole group 1 week before expected clinical signs: Requires excellent records, knowledge of previous coccidiosis outbreaks & management history in herd/flock.
Unknown
Treat 2 weeks after exposure or treat at time of stress factor (e.g. dehorning, castration, transport, weaning, regrouping etc.)
Clinical Outbreak
Reactive treatment: Treat all calves in a group when diarrhoea is first seen in 1 or 2 calves/lambs
It is important to always treat all the calves in the group, as coccidiosis is a group problem, not an individual problem.
A single administration to susceptible animals during risk periods is appropriate although a re-treatment may be necessary if the period of risk is prolonged.
