In the literature there is no complete data on the use of slaked lime as a disinfectant disinfectant. All veterinary publications indicate that a 10 - 20% solution of slaked lime has a disinfecting effect. However, the technology of carrying out, as well as modes of disinfection, are not specifically indicated in any literature. There is no data on which infectious diseases they affect, at what concentration, exposure and consumption of the disinfectant it can be applied, on smooth or rough surfaces, the frequency of whitewashing or wet disinfection, etc. Until now, the issue of the solubility of slaked lime in water and other chemical compounds has not been completely resolved. In addition, the lack of a disinfectant - 10 - 20% slaked lime, is a low disinfection efficiency, high corrosion activity in relation to metal products, a large flow rate of a solution of 1 -1.5 l / m2, which is carried out 2 - 3 times by whitewash.

Aim. To test the effectiveness and environmental friendliness of a new method of biothermal treatment of bird litter and disinfectant – Penoks‐2 – in relation to bird coccidia oocysts.Material and Methods. A test of biothermal disinfection of bedding manure and disinfestation of premises for rearing young laying hens (6000 birds), was carried out in the Mugutdinova farm of the Buynaksky district of the Republic of Dagestan. The detection of coccidia oocysts was carried out according to the method of Void and Darling, Methods for the Laboratory Diagnosis of Avian Coccidiosis". The quality of the disinfestation using Penox‐2 solutions was controlled by examining swabs and scrapings taken from the experimental and control surfaces of the premises in accordance with the Rules for Disinfection and Disinfestation of Objects of State Veterinary Supervision. The study of biothermal processes in the litter manure was carried out every 5 days with temperature measurement of piles, while taking samples of the litter for detecting the presence of coccidia oocysts.Results. The studies conducted established that the most environmentally safe method of disinfecting premises is biothermal where the population of replacement laying hens is kept. The temperature in piles 1.5 and 2.0 m high and 2–2.5 m wide reached 65–75°C on the 20–25th day, which ensures the destruction of coccidia oocysts. Production tests have shown that solutions of the new Penox‐2 agent destroy coccidia oocysts in the external environment after irrigation of room surfaces with a content of 3.0% chloramine B through a single application at the rate of 0.5 l/m2 and 3 hours exposure.Conclusion. Tests of a new method of biothermal treatment of litter manure and disinfestation with solutions of Penox‐2 showed high efficiency and environmental safety in the destruction of coccidia oocysts.

The results of laboratory and production tests of the effectiveness of the disinfectant Palocid for the disinfection of objects of veterinary supervision are presented. As test microorganisms were used the museum cultures of E. coli (strain 1257), Staphylococcus aureus (strain 209-P), bacilli (strain B5), B. cereus (strain 96). Inactivated blood serum of the horse was used to simulate natural contamination of surfaces. The quality of the disinfection was controlled by examining the washings from the test and control test objects for the presence of a given test culture. The results of laboratory and industrial tests show that Palocid is an effective disinfectant and can be recommended for preventive and forced disinfection in livestock, poultry, fur farming, automobile and railway transport, while monitoring its quality in the isolation of bacteria of the E. coli and staphylococcus group, as well as forced disinfection at the objects of veterinary supervision for infectious diseases of bacterial (including tuberculosis) and viral etiology, especially dangerous infections (anthrax and other spore infections).
