Safe-Guard AquaSol is indicated for the treatment and control of adult Ascaridia galli and Heterakis gallinarum. Safe-Guard AquaSol was initially approved in October 2015 for the treatment and control of adult A. galli in broiler chickens and replacement chickens intended to become breeding chickens and for the treatment and control of adult A. galli and H. gallinarum in breeding chickens.

“Managing gastrointestinal health properly helps in creating better overall performance – uniformity, productivity and profitability,” said Ivan Alvarado, D.V.M., Director, Poultry Technical Services, Merck Animal Health. “Effective management also helps to minimize the economic impact that comes as a result of production losses, which is a priority for all of our customers.”

Safe-Guard AquaSol is produced with an innovative wet-milling technology, which produces a highly stable suspension that can be conveniently administered through drinking water for a short, five consecutive-day treatment period. The product’s smaller particle sizes help to prevent sedimentation and clogged pipes, filters or nipple drinkers. There is no pre-slaughter withdrawal period when used according to the product label.

“Since launching Safe-Guard AquaSol for broilers and breeders we have received positive feedback from producers about how the product has helped in their operations. The expanded label use will allow commercial layer producers to experience the convenience and effectiveness of this treatment,” he added.

Safe-Guard AquaSol is available in 1 liter and 1 gallon presentations. For more information about this product, contact your Merck Animal Health sales representative.

Safety Information:

No withdrawal period is required when used according to the label. Consult your veterinarian for assistance in the diagnosis, treatment and control of parasitism.
