Abstract

1. Enterococcus cecorum (EC) infection in chicks must be prevented because of its severe pathogenicity in poultry farming. In this study, the combined sanitising effects of sodium hypochlorite (NaClO) and carbon dioxide microbubbles (CO₂MB) on artificially applied EC on eggshells were clarified and the effectiveness for sanitising fertilised eggs was investigated.2. The number of surviving EC cells on eggshells decreased with increasing chlorine concentration and treatment time, with the NaClO solution containing CO₂MB. The spray treatment of the NaClO solution containing CO₂MB was more effective for sanitising EC.3. In addition, sanitisation of EC on fertilised eggs using a NaClO solution containing CO₂MB was effective in preventing contamination in the setter, without negative effects on hatching or early growth of chicks.4. Using NaClO solution containing CO2MB was an effective method for sanitising EC on fertilised eggs.

利用二氧化碳微泡和次氯酸钠对附着在受精卵壳上的盲肠球菌进行消毒。

1. 盲肠球菌（Enterococcus cecorum， EC）在家禽养殖中具有很强的致病性，必须预防雏鸡感染。本研究阐明了次氯酸钠（NaClO）和二氧化碳微泡（CO2MB）对蛋壳上人工施用EC的联合消毒效果，并考察了其对受精卵的消毒效果。在含CO2MB的NaClO溶液中，蛋壳上EC细胞的存活数量随着氯浓度和处理时间的增加而减少。含CO2MB的NaClO溶液喷雾处理对EC.3的消毒效果更好。此外，使用含有CO2MB的NaClO溶液对受精卵进行EC消毒，可有效防止setter中的污染，对雏鸡的孵化或早期生长没有负面影响。用含CO2MB的NaClO溶液对受精卵上的EC进行消毒是一种有效的方法。

期刊介绍： From its first volume in 1960, British Poultry Science has been a leading international journal for poultry scientists and advisers to the poultry industry throughout the world. Over 60% of the independently refereed papers published originate outside the UK. Most typically they report the results of biological studies with an experimental approach which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: anatomy, embryology, biochemistry, biophysics, physiology, reproduction and genetics, behaviour, microbiology, endocrinology, nutrition, environmental science, food science, feeding stuffs and feeding, management and housing welfare, breeding, hatching, poultry meat and egg yields and quality.Papers that adopt a modelling approach or describe the scientific background to new equipment or apparatus directly relevant to the industry are also published. The journal also features rapid publication of Short Communications. Summaries of papers presented at the Spring Meeting of the UK Branch of the WPSA are published in British Poultry Abstracts .
