The efficiency of different methods of disinfection of the surface of hatching eggs

Abstract

One of the vulnerabilities of poultry farms is a hatchery, since microorganisms can survive the entire incubation period, they penetrate through the eggshell, infect embryos, thereby reducing egg hatchability and causing the mortality in the first days. The efficiency of different methods (aerosol spraying and «cold fog» method) for disinfecting hatching eggs with «Anolyte ANK SUPER» was studied. To conduct the test, eggs were divided into 3 groups, one was control group, the others were test groups, each group consisted of 90 eggs, the parent stock was meat chicken breeds, Ross-308, at the age of 54 weeks. The eggs were treated in a special chamber equipped with input and exhaust system of ventilation. The eggs of the first group were treated with a 37% aqueous solution of formaldehyde twice by aerosol spraying. The eggs of the second and third groups were treated with «Anolyte ANK SUPER» twice (for the first time - not later than two hours after the laying, and then before placing the eggs into the incubator). The disinfecting agent was used at the dose of 30 ml per 1 m3 of chamber, the second group was treated by aerosol spraying, and the third group was treated by «cold fog» method with a power generator (model 2610). The mode and exposure of treatments were similar in all groups. Samples to conduct a bacteriological test for the total bacterial count (TDC), E.coli and Salmonells were taken before and after the treatment. The use of the disinfecting agent by both methods, decreased the bacterial and increased the egg hatchability by 1.2-5.8%.
