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

Effects of Sanitizers on Microbiological Control of Hatching Eggshells and Poultry Health during Embryogenesis and Early Stages after Hatching in the Last Decade

“…This reduces the risk of bacterial infection for embryos and chicks during the early stage of their life, supported by the significant reduction in Escherichia coli in the yolk sac. The hatching egg must also be of quality to minimize cracks or shell breaks, reduce incubation residues and infection of birds and increase immunological resistance [ 78 ]. In addition, litter eggs should be avoided, as the dirtier the shell, the greater the possibility of containing more pathogenic microorganisms [ 63 ].…”

“…Cantu et al [ 72 ] reported the best percentage of hatching ducklings without defects after sanitizing was with hydrogen peroxide plus ultraviolet light. Sanitizers such as Polydez (which contains hydrogen peroxide, benzalkonium chloride, cocamidopropyl betaine, neonol and other components) and Virosan (which contains benzalkonium chloride, glutaraldehyde and excipients) did not harm the development of poultry in the embryonic and post-hatch period [ 78 ]. In vitro and in vivo tests performed by Patrzałek et al [ 79 ] confirmed that sanitizing eggs with Dergall (organomodified trisiloxanes) is not toxic to chicken embryos.…”
