摘要

作为质量保证体系的一部分,孵化蛋消毒是商业孵化场的标准程序。甲醛在过去和现在都被广泛使用,但对人体的危害很大。在初步研究中,成功地测试了双氧水喷雾的应用,并选择在田间条件下比较其效果和对孵化率的影响,以及在育肥期间和屠宰时对甲醛的影响。试验设置了两个种鸡群的孵化蛋,在4个不同的鸡龄(38、39、56、57周)分别分成3组(H2O2、甲醛和未消毒对照组)平行运行。在孵化场没有发现显著差异,而在饲养期间,试验1和试验2中所有未消毒组和一个甲醛处理组的7天死亡率和总死亡率较高,因此需要进行抗生素治疗。在屠宰时,所有组的结果都具有可比性。试验3和4在所有组之间没有显着差异,从而得出结论,孵化蛋消毒降低了感染相关损失的风险。同时,甲醛熏蒸和过氧化氢喷雾在各阶段的效果相似。

Impact on Hatchability and Broiler Performance after Use of Hydrogen Peroxide Nebulization versus Formaldehyde Fumigation as Pre-Incubation Hatching Egg Disinfectants in Field Trial
Hatching egg disinfection, as part of the quality assurance system, is a standard procedure in commercial hatcheries. Formaldehyde was and is broadly used but bears high risks for the personnel. In preliminary studies, the spray application of hydrogen peroxide was successfully tested and was chosen to compare its efficacy and impact on hatchability, as well as performance during fattening, and at slaughter, to formaldehyde under field conditions. The trial was set up with hatching eggs from two breeder flocks, running parallelly in three groups (H2O2, formaldehyde and non-disinfected control) at four different flock ages (at 38, 39, 56, 57 weeks). No significant differences were noticed in the hatchery, whereas in the rearing period higher 7-day- and total mortalities occurred during trials 1 and 2 in all non-disinfected groups and one formaldehyde-treated group, making an antibiotic treatment necessary. At slaughter, the findings in all groups were comparable. Trials 3 and 4 passed without significant differences between all groups, leading to the conclusion that hatching egg disinfection lowers the risk of infection-related losses. Meanwhile, formaldehyde fumigation and the spraying of hydrogen peroxide produced similar results in all stages.
