Abstract

The ultimate success of a hatchery depends, among other factors, on the fixed and variable costs of incubation incurred in the production of day-old chickens. In this regard, the objective ofthe research was to check the applicability of the extreme ultraviolet rays and negative ions in the production practice of the broiler chicken hatchery, as the alternative means of the hatching egg sanitary treatment and, by comparison with the conventional sanitary treatment by formaldehyde vapors (control treatment), their economic justification expressed as variable costs of incubation. Variable costs of the sanitary treatment for 16,500 hatching eggs, through four experimental incubation cycles, with formaldehyde vapors, ultraviolet rays and the combined treatment with negative ions and ultraviolet rays were 157.93 €, 30.90 € and 54.60 €, respectively.Compared with the reference treatment by formaldehyde vapors, the share of variable costs for the experimental treatment in the price of one-day chicken was 18.72% when using ultraviolet rays and 30.76% for the combined use of ultraviolet rays before the start of incubation and application of negative ions in the incubator continuously during the first 18 days of incubation.Using positive economic indicators, good hygienic and production effects of the alternative sanitary treatments of the poultry hatching eggs were validated and confirmed in production conditions. Combined application of ultraviolet rays and negative ions as a substitute for formaldehyde vapor fumigation of the poultry hatching eggs has both economic and every other justification.
