Method of providing a domestic animal with liquid food, which comprises:
- providing liquid food for domestic animals in a storage tank of an automatic drinker system;
- passing liquid food from said storage tank to a suckling point for said domestic animal via a suction line;
- connecting a pressure sensor to said suction line upstream of the suckling point, connecting at least one feed pump to said suction line;
- measuring the quantity of liquid food removed from said suckling point by said domestic animal upstream of the suckling point;
- and including at least one of the following:
- (1) connecting the feed pump to a switch operative to activate the feed pump, and (2) switching the feed pump to throughflow in the event of a stoppage in the flow of liquid food to the suckling point, and including providing a connection of the suction line between the suckling point and the storage tank which is open for suckling with virtually no resistance to the flow of liquid food.
