To obtain optimal benefit from the persistent activity of Virbamec Pour-On for grazing animals, it is recommended that calves which are set stocked in their first grazing season should be treated 3, 8 and 13 weeks after the day of turn-out. Studies have shown that first-season grazing calves turned out to pasture in late April or May and treated with Virbamec Pour-on 3, 8 and 13 weeks after turn-out can be protected from parasitic gastro-enteritis and lungworm disease throughout the grazing season, provided they are set stocked, all the calves are included in the programme and that no untreated cattle are added to the pasture.
Treated animals should always be monitored according to good husbandry practices.

Dosage and administration

1ml per 10 kg bodyweight (based on a recommended dose rate of 500mcg per kg bodyweight).
The formulation should be applied along the mid-line of the back in a narrow strip between the withers and tailhead.
