COMPARATIVE EVALUATION OF THE EFFICACY OF VARIOUS SANITIZERS IN A POULTRY HATCHERY

摘要

Disinfection procedures in hatcheries are an important part of the general set of anti-epidemic measures in poultry breeding and therefore justify the necessity of studies to evaluate the achieved disinfection effect. This study presents the results of a controlled trial with disinfectants from three chemical groups – the commercial preparations “Dezinfect-B,” “Sanifort,” and sodium hydroxide – on the efficacy of disinfection in a poultry hatchery. Control was performed through microbiological tests on samples from surfaces, obtained before and after their disinfection. The effect of the performed disinfection procedures was evaluated through the achieved microbial count reduction, residual microflora, and detection of the presence of indicator bacterial species. A higher efficacy was established for treatment with 2% solution of sodium hydroxide and 0.025% solution of Sanifort (99% sodium dichloroisocyanurate dihydrate) compared to disinfection with 3% solution of Dezinfect-B, containing 1.6% iodine with exposure times of 60 min.
