Solubility in water varies depending on temperature and water quality. Under worst
case conditions

confirmed.
When using a proportioner, adjust flow rate settings of the dosing pump and adapt
the volume of preparation accordingly depending upon water intake of animals to be

When using a water tank, it is recommended to prepare a stock solution and to dilute

Before each administration the powder should be thoroughly mixed into a small
amount of feed and should be given directly to the animal before the main ratio. Care
should be taken to ensure complete consumption of all medicated feed prior to
providing the remained of the daily feed ratio.
Continuous free access to drinking water should always be ensured, in particular
immediately after the meal.
