Effectiveness of the use of sanifying set «SanStim» for disinfection eggs before incubation

The most vulnerable place in poultry farms is incubation, microorganisms are able to survive the entire period of incubation and penetrate through the eggshell, to be the source of infection with embryos, to affect the reduction of the percentage of conditional young birds, growth and development in the early days of cultivation. The accumulated pathogenic microflora negatively affects the state of the immune system of the bird. Contaminated with conditionally pathogenic and pathogenic microflora egg is the main link in the transmission of all bacterial infections. In Ukraine, for the pre-incubation treatment of eggs, sodium hydroxide, formalin, chloramine, persicum C. are used. These agents exhibit bactericidal properties, but are toxic, have corrosive activity and are carcinogens. The «SunTime» kit consists of polyhexamethylene guanidine hydrochloride and a mixture of organic acid salts (lemon, amber, and apple). These substances provide an effective bactericidal action against a wide range of bacteria, are safe for poultry embryos and personnel, have a stimulating effect on the growth and development of the embryo, provide a prolonged bactericidal action. The purpose of the study of the effectiveness of a complex ecologically safe sanitizers set «SunSim», its application for pre-incubation processing of chicken eggs. In experimental studies, two groups were formed, each with n = 250. In order to disinfect the surface of the shell of the incubation egg, two times aerosol treatment of the experimental group using 0.3% of SunStim was carried out, the first time the sanitation of the incubation eggs was carried out before the laying on the incubation cabinet, the exposure was 40 minutes, the second final treatment was carried out on the 18th day of incubation, to extract, a working solution of organic acids (amber, lemon and apple) to stimulate embryonic viability and increase the natural resistance of the embryos. For the control group, formalin was used. After two times of the sanation of the incubation eggs with the SunStim set, the percentage of decontamination of the shell surface of the incubation eggs was 99.1 ± 0.5%. While analyzing the results of the incubation waste category of «dead and drowning» by 3,6% less compared with the control, and the category of «crippled» was not observed. The use of the SunStim set improves the quality of surface treatment of the shell of incubation eggs, increases the incubation eggs output by 4.5-5.0%, the average body weight of the received young animals in experimental groups exceeds control by 4%.
