Comparative assessment of the effect of disinfectants on the level of biotic contamination and hatchability of chicken eggs

Abstract

The widespread presence of modern high-productive egg crosses of chickens in poultry farms causes some negative consequences, one of which is a decrease in hatchability and survival of young chickens. The worsening of the quality of hatching eggs is associated with a violation of the morphological and biochemical parameters of the shell and shell membranes, which leads to the egg breakage, increased hatchery waste, contamination of young birds with infectious agents, and reduced immune resistance. Modern poultry farming uses a fairly large arsenal of disinfectants of various chemical origins and mechanisms of action. The introduction into practice of disinfectants is not possible without prior laboratory evaluation of their effectiveness as to the object of intended use. The aim of our work was to determine the bactericidal properties of disinfectants with different active substances in relation to the microbiota of hatching eggs from chickens of different productivity directions. The research was conducted following the guidelines ‘Methods for determining and evaluating the safety and quality of disinfectants, detergents and detergent-sanitizers used in the production, storage, transportation and sale of animal products’ (Kotsiumbas et al., 2010). According to the results of the research, it was found that for the purpose of pre-incubation treatment and during the incubation period for chickens it is effective to use the drug ‘Polydez’ in 0.1% concentration and the drug ‘Virosan’ in a concentration of 0.1%. These disinfectants can be used for sanitation of chicken hatching eggs and hatcheries
