Productivity and economic efficiency of keeping turkeys of the parent herd on the litter regenerated in different ways

Abstract

Goal. To determine productive indicators and economic efficiency of keeping turkeys of the parent herd on the litter regenerated in different ways. Methods. Zootechnical (study of poultry zootechnical indicators), zoohygienic (study of microclimate parameters), statistical (statistical data processing), and economic (calculation of economic efficiency). Applied methods of litter regeneration included its pasteurization by the biothermal composting method, the addition of special microbiological preparation and disinfection of the surface of the litter with ozone (1st method) or irradiation with ultraviolet radiation (UVR) (2nd method). Results. Probable differences in the main indicators of productivity between turkeys kept on new and regenerated litter in various ways were not established, although the indices of turkeys kept on litter regenerated by irradiation of the surface of the side with UVR were somewhat better in numerical terms. Costs associated with the use of litter regenerated with ozonation were 5 times lower, and with the use of litter regenerated with UVR 6.1 times less than with the use of new litter. Due to the reduction of litter costs, the economic effect of using regenerated litter compared to new in the case of applying the regeneration method involving ozonation was UAH 84.99, and in the case of applying the regeneration method using UVR — UAH 124.77. Conclusions. Keeping turkeys of the parent herd on litter regenerated with the use of methods developed at the State Poultry Research Station of NAAS did not lead to a deterioration in the productivity of poultry, but contributed to an increase in the economic efficiency of incubatory egg production.
