Efficiency of growing repair young chickens on regenerated litter

Abstract

Goal. To determine production indicators, poultry welfare, and economic efficiency of growing repair young chickens on litter regenerated in different ways. Methods. Zootechnical (determination of production indicators of poultry), zoohygienic (determination of ammonia content in the air), statistical (statistical processing of data), and economic (calculations of economic efficiency). The methods of regeneration of the litter used included its disinfection by biothermal composting, as well as the addition of special microbiological preparation and subsequent disinfection of the surface of the pile with ozone (method 1), or irradiation using ultraviolet radiation (method 2). Results. It was found that throughout the growing repair young chickens, the operational properties of the regenerated litter in both experimental versions corresponded to its functional purpose as a litter material. Statistically probable differences between repair young chickens grown on new and regenerated litter in different ways, according to the main production indicators and indicators of poultry welfare were not found. Costs for regenerated by method 1 litter was 1.7 times less, and for regenerated by method 2 –2.1 times less than for the use of new. Due to this, the economic effect in the case of using the regeneration method 1 was 7.04 UAH/bird, and in the case of using the method 2–7.26 UAH/bird. Conclusions. Growing repair young chickens on litter, regenerated using the developed methods, did not lead to a deterioration in the productive performance and well-being of the bird, but contributed to an increase in economic efficiency — by 7.04 UAH/1 bird (method 1) and 7.26 UAH/1 bird (method 2).
