ABSTRACT:
The equipment includes a set of feed distribution stations each furnished with a mixer supplied with milk powder, water, milk from a tank and various additives from a set of measuring pumps whose number of rotations is controlled by computer system depending on the feed mix to be composed. The measuring pumps are primed by the additive supply tanks. There are as many tanks as additives to dispense. The set of measuring pumps at each feeding station withdraws the selectively programmed quantity from each tank depending on the mix to be constituted. Each animal that is present at a station and that is identified, is credited with a volume of feed that is around 500 grams, whose composition depends on the animal's previous intake, on the weight newly recorded, and on other criteria. The station mixes the feed on demand while the animal is ingesting it. There always remains a certain volume of feed in the mixer after the departure of the animal. This volume is subtracted from the animal's credit so as to precisely calculate the animal's feed intake.
