Abstract
A method of providing domestic animals with liquid food which passes from a storage tank, in particular a mixing tank of an automatic drinker via a suction line to a suckling point, the quantity of liquid food removed is to be determined ahead of the suckling point.
Claims29
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;
- and measuring the quantity of liquid food removed from said suckling point by said domestic animal upstream of the suckling point, including at least one of the following:
- (1) wherein the quantity of liquid food removed from said suckling point by said domestic animal is measured by means of the opening time of at least one valve downstream of the storage tank, and (2) wherein pressure fluctuations are determined in said system to calculate the quantity of food in the suction line.
