“…The study on the eggshell quality trait after disinfection can reflect the destruction of the surface structure of the eggshell. The results of this experiment prove that the SAEW and BBS treatment did not affect the eggshell strength and eggshell thickness, which was consistent with the result of Melo et al (2019) , who found that hydrogen peroxide spraying, per acetic acid spraying, and water spraying did not affect eggshell quality. When the solution sprayed out, the mist covered the surface of the eggshell that had a smaller contact area and degree than immersion disinfection, and would not damage the strength and thickness of the eggshell.…”

“…First, although from the current concentration, 150 mg/L SAEW has the highest sterilization effect, it is unknown whether SAEW with a higher concentration will have a higher bactericidal effect or remain stable. Second, the morphology of eggshells was usually directly measured by electron microscopy ( Melo et al, 2019 ), while we used a dyeing method reported by Chen et al (2019) . And the result of the opacity of cuticle in BBS treated groups were larger may be due to the limitations of the dyeing method.…”

Conventional chemical disinfectants used for egg disinfection could result in toxic residue and endanger hatchability, chick quality, and pullet growth performance. Slightly acidic electrolyzed water ( SAEW ) is known as a novel disinfectant for egg sterilization due to its high efficiency and no residue. In this study, a comprehensive assessment of slightly acidic electrolyzed water and benzalkonium bromide solution ( BBS ) used in the disinfection channel was conducted to assess the microbial count, eggshell quality, and hatchability concomitantly. The results show that the sterilization efficiency of SAEW increased with an increase in available chlorine concentration ( ACC ), spraying volume, and sterilization duration. SAEW with an ACC of 150 mg/L and 10,000 mg/L benzalkonium bromide solution had the same sterilization rates of approximately 86.2% at a spraying volume of 0.5 mL/egg and sterilization duration of 180 s. Neither had significant effect on eggshell strength or thickness. The eggshell cuticle quality in the benzalkonium bromide group was significantly higher than the control group (no disinfection) and the 150 mg/L SAEW group. The embryo weight, relative embryo weight, hatchability, and embryonic mortality in the SAEW group had no significant differences of those in the benzalkonium bromide group. SAEW should be more popular because of its simple preparation, low cost, and no residue. Our results indicate SAEW is an alternative disinfectant for the sterilization of hatching eggs instead of conventional chemical disinfectants, such as benzalkonium bromide, and give a recommendation is using SAEW as a disinfectant with 150 mg/L ACC, 0.5 mL/egg spray volume, and disinfection for 180 s in the novel disinfection channel.

“…The use of peracetic acid on hatching eggs lead to a significant reduction of aerobic bacteria and a significant reduction of Enterobacteriaceae and was suggested as possible alternative for formaldehyde hatching egg disinfection. [21] UV light was tested alone [22] and in combination with hydrogen peroxide [23] with a favorable effect on bacterial contamination due to advanced oxidation processes resulting in the production of highly reactive oxygen species. [23] A disadvantage was heat development when application times exceeded 8 minutes.…”

Oregano essential oil (OEO), one kind of Labiata has been known for a long time as a popular remedy. The essential oil of oregano has anti-bacterial, anti-oxidant, anti-fungal and nematicidal properties mainly due to the basic constituents. Once the shell's microbial barriers have been breached, Gram-negative bacteria are more capable of withstanding the antimicrobials present in the albumen. Eggs were divided into, control group (GI), LPS group (GII) and LPS plus OEO 0.5% group (GIII), as natural disinfectants. Statistical data were analysed, histopathological, RT-PCR and in situ hybridization studies were performed to explain the OEO modulatory role. Lipopolysaccharide (LPS) group represented the highest (P < 0.05) increase of embryonic mortality percentage, greatest significance (P < 0.01) egg weight loss, a decrease of hatchability and high teratogenic effect compared with those for other groups in all types of experiments. Chicks produced from egg subjected to oregano 0.5% and LPS significantly (P < 0.05) recorded large body weight gain, enhancement of hatchability and produces no teratogenic effects in the developing chicken. OEO modulates the effect of LPS in histopathological, RT-PCR and in situ hybridization studies throughout modulation of the Daam2 and Tbx2 gene expression towards the normal one. Using Oregano oil as a natural disinfectant in this study modulate significantly the effect of LPS oxidative effect on the chick embryo even after hatching, so, we conclude that OEO is an effective anti-oxidant that recommended to be used in hatchery for good quality chicks, chick growth and finally improvement of laying production performance.
