Effect of a Drinking Water Conditioner on Stability and Efficacy of Fluralaner in Laying Hens Infested with Poultry Red Mites.

Concurrent use of a colorant during drinking water treatment could contribute to the correct application of fluralaner to poultry. The present studies therefore examined whether the blue-colored drinking water conditioner Vac-Safe has an influence on the stability of fluralaner in water and/or on its efficacy for the control of poultry red mites (PRM). Laboratory trials showed that fluralaner dissolved at various concentrations in water conditioned with Vac-Safe retained full stability for at least 27 hr at temperatures up to 40 C.
