Coccidians treatment and disinfection,
Ammonium Hydroxide has been reported as a highly effective disinfectant against oocysts. An old but effective system to control coccidiosis in an empty house is use of slated lime and ammonium sulphate: per 100 m2 floor surface 10 kg of Calcium Hydroxide (slated lime) and 20 kg of Ammonium Sulphate (fertiliser) is spread on the floor and approximately 100 litres of water is sprayed on top. This will produce a high level of ammonia, killing the oocysts. It also produces a gypsum, which will help to cover remaining oocysts in cracks in the floor. Use a proper gasmask when applying this system!
