The OPIS Controller is an automated mineral dosing system for herds of 100 + animals. The OPIS integrates into the herd water supply and allows farmers to dose up to six customised liquid mineral blends via the water supply, to up to three separate animal groups at the same time. The OPIS can be installed indoors or outdoors. It is connected to a water meter, which monitors how much water is being consumed by the herd(s), allowing the farmer to increase or decrease the concentrates of the minerals being dosed. Using the OPIS system on farms delivers precision nutrition to your herd, ensuring healthier animals, increased returns and less labour.
