An experiment was conducted to determine whether spraying hatching eggs with electrolyzed oxidizing (EO) water would decrease eggshell microbial load and hence improve hatchability, chick quality, and broiler growth performance. Eggs were collected from a broiler breeder flock; half the eggs were sprayed with EO water and the other half were left untreated. Enterobacteriaceae and total aerobic bacteria present on the eggshells of eggs from both treatments were enumerated. The eggs were incubated, and the broiler chicks were grown out to 39 d. Eggshell microbial load was significantly decreased by spraying the eggs with acidic EO water before incubation, with no effect on cuticle structure [as measured by egg weight (moisture) loss], normal embryonic development, and hatchability. Chick quality, as determined by visual assessment and BW at the time of hatch, was also not affected. However, broiler mortality during the first 2 wk of the production period was significantly reduced in the chicks that hatched from eggs sprayed with EO water compared with chicks hatching from control eggs. The ability of EO water to reduce eggshell microbial load without negatively affecting hatchability or chick quality may make it a useful product for hatching egg sanitation.
进行了一项实验，以确定用电解氧化（EO）水喷洒孵化蛋是否会降低蛋壳微生物负荷，从而提高孵化率、雏鸡质量和肉鸡生长性能。从一个肉种鸡群收集鸡蛋；一半的鸡蛋用EO水喷洒，另一半不做处理。对两种处理的鸡蛋蛋壳上存在的肠杆菌科细菌和总需氧菌进行计数。将鸡蛋孵化，肉鸡雏鸡饲养至39日龄。在孵化前用酸性EO水喷洒鸡蛋可显著降低蛋壳微生物负荷，对角质层结构（通过蛋重（水分）损失测量）、正常胚胎发育和孵化率没有影响。通过视觉评估和孵化时的体重确定的雏鸡质量也未受影响。然而，与对照蛋孵化出的雏鸡相比，用EO水喷洒的蛋孵化出的雏鸡在生产期前2周的死亡率显著降低。EO水在不负面影响孵化率或雏鸡质量的情况下降低蛋壳微生物负荷的能力，可能使其成为一种用于孵化蛋卫生处理的有用产品
