Floating dispenser for water trough dosing

    Hoping to dose animals (calves) via drinking water trough for multivitamins + parasites. Does anyone have any experience of floating dispensers, cost + effectiveness? I am hoping to source a floating dispenser where I can vary the dosage depending on the number of animals + treatment I use.

    Here is a blurb on water dispensers....
    Pumps versus simple dispensers: Soluble medicaments can be added to the water in two ways: by a pump (plumbed into the mains supply) or by a simple plastic dispenser floated in the trough.

    Pumps usually maintain a fixed concentration of medicament in the water. As weather conditions vary widely between days, intake of water and the water-soluble medicament also varies by up to 15-fold between days. Therefore, pumps delivering a fixed dose/water ratio can not ensure an even intake of medicament on a day-to-day basis.

    Dispensers: Water medication, via a Ruakura-type plastic dispenser, with compounds that remain in solution has advantages over pumps and over oral free access supplements. (Dispensers are technically better than pumps. Due to wide variation in water intake between days, day-to-day variation in mineral-dose intake can be 7-14-fold, or more, from water medicated by pumps that maintain a constant dose level in water). A predetermined daily dose can be added to the water trough. This reduces day-to-day variation in mean intake of dose to almost zero, irrespective of day-to-day variation in mean water intake. Between-animal variation in dose intake in any given day is likely to be as little as 2 to 4-fold, as compared with 10 to 30-fold or more on free-access supplements.
