Abstract
The invention relates to a method for rearing animals and in particular poultry or pigs that comprises supplying the animals with drinking water in order to water the animals, injecting oxygen and CO2 into the drinking water, before the drinking water reaches the animals, according to one of the following modes: two injections, one of CO2 and one of oxygen, are carried out simultaneously into the drinking water, or one injection, a mixture of oxygen and CO2, is carried out into the drinking water.
Claims2
A method for oxygen-doping of poultry drinking water with calcium carbonate control, the method comprising
- supplying the animals with drinking water;
- and
- injecting oxygen and CO2 into the drinking water, before the drinking water reaches the animals, according to the following mode:
- one injection of a mixture of oxygen and CO2 is carried out, wherein the mixture of oxygen and CO2 contains a fixed percentage of CO2 to keep a constant level of dissolved CO2 of between 3 and 20 mg/L in the drinking water, thereby avoiding formation of calcium carbonate.
