Do not use in animals intended for human consumption.
Why do various packages of DAC medicines specify, along with a quantity per litre of drinking water, ‘= 20 pigeons or 10 kilos of body weight’?
It is assumed that 20 kilos of pigeons consume about 2 litres of water per day. This is an average figure, however, since animals drink less in cold weather and more in hot weather, DAC specifies for the drinking water quantity the number of grams you have to administer per animal or per kilo of body weight. (This is the amount of medicine per animal or kilo per day which should be ingested for the desired effect). If you want to administer medicine in drinking water, you should always add it to an amount of water you are certain will be consumed in one day. This measure ensures no water is thrown away which contains a residue of medicine, thereby depriving your birds of the correct amount. For the record, one carrier pigeon weighs 400 to 500 grams so 1 kilo of body weight equals about two carrier pigeons.
Why can DAC medicines be added to drinking water and feed alike?
The two options allow you to administer the medicines to your pigeons in the way that suits you best. Medicine in drinking water (dissolved in the water bowl) does have one great advantage, however. When pigeons are transported, they are exposed to all kinds of infections. During transport and the actual flight the chance that they catch something is by no means ruled out. When the pigeons come home, you obviously want to be sure there is no chance for them to infect – through the drinking water pan – the pigeons which stayed at home. This is why drinking water medication is highly recommended. An ornithosis mix in the drinking water not only controls any disease germs present but prevents the transmission of infection!
Finally, we want to emphasize an important principle in the administration of medicine to your pigeons. Always maintain the recommended amounts. One spoonful more does not result in extra effect; one spoonful less does not work adequately!
