Recently, individual data of the fertile eggs are digitized for information processing. Then we thought we can employ the data printed sticker putting on the egg to sort out the eggs correctly and readily. In this study, we investigated the effects on the disinfection on the eggshell and the hatching results. In Experiment 1, standard agar mediums which had been applied with E. coli, were stickered labels and were sterilized by fogging Hyperoxsup(R), and then the disinfection effects on the eggshell surface and adverse effects of the sticker were examined. In Experiment 2, we investigated contamination level of egg samples as below with standard agar mediums: eggshell surfaces before and after disinfection, stickered eggshell surfaces and sticker surfaces. In Experiment 3, the effects of the sticking label on hatching results were compared. No bacterial colony was confirmed (experiment 1), therefore, it is suggested that fogging disinfectant is effective even from above the label sticker. The contamination level of all samples after disinfection were lower than eggshell surfaces before disinfection (P<0.05) (experiment 2), thus, we suggest that fogging disinfection is effective. There were no significant differences in hatching results by sticking of the label sticker (experiment 3). These data indicated that covering the eggshell surface with the label sticker doesn't cause a problem and has little influence on production of chicks. These results show that the data sticker to the fertile egg is an available technique for individual identification and information processing.
