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.
传统的用于鸡蛋消毒的化学消毒剂可能会导致有毒残留物，从而危害孵化率、雏鸡质量和母鸡生长性能。微酸性电解水（SAEW）由于其高效且无残留而被认为是一种新型的鸡蛋灭菌消毒剂。在这项研究中，对用于消毒通道的微酸性电解水和苯扎溴铵溶液（BBS）进行了综合评估，以评估微生物计数、蛋壳质量和孵化率。结果表明，SAEW 的杀菌效率随有效氯浓度（ACC）、喷雾量和杀菌时间的增加而增加。ACC 为 150mg/L 和 10,000mg/L 的 SAEW 与 0.5mL/个蛋的喷雾量和 180s 的杀菌时间的杀菌率相同，约为 86.2%。两者均未对蛋壳强度或厚度产生显著影响。苯扎溴铵组的蛋壳表皮质量明显高于对照组（未消毒）和 150mg/L SAEW 组。SAEW 组的胚胎重量、相对胚胎重量、孵化率和胚胎死亡率与苯扎溴铵组无显著差异。SAEW 因其制备简单、成本低且无残留而应该更受欢迎。我们的研究结果表明，SAEW 是一种替代传统化学消毒剂（如苯扎溴铵）的孵化蛋灭菌消毒剂，建议在新型消毒通道中使用 150mg/L ACC、0.5mL/个蛋喷雾量和 180s 消毒时间的 SAEW 作为消毒剂。
