- W2011567762 abstract "유정란의 부화과정 동안 소모되는 산소와 배출되는 이산화탄소의 양을 기체질량분석기를 사용하여 측정하였다. 20 일에 걸친 유정란과 무정란의 인공부화 과정 동안 기체 시료를 채취하기 위해 밀폐된 구조의 시료 챔버를 제작하였다. 2~4 일 간격으로 시료 챔버 안에 유정란을 1 시간 동안 방치한 후, 실린지를 이용해 밀폐된 시료 챔버로부터 2 mL의 기체 시료를 채취한 후 기체질량분석기를 사용하여 분석하였다. 인공부화를 시작한 후 약 10 일 후부터 닭 배아의 산소 소모량과 이산화탄소 배출량이 급격히 증가하였다. 20 일 후에는 시간당 23 mL의 산소를 소모하고 16 mL의 이산화탄소를 배출하였다. 전체 부화 기간 동안 산소의 농도는 4.3 mol% 감소하였고 이산화탄소의 농도는 3.1 mole% 증가하여 소모된 산소의 몰수와 배출된 이산화탄소의 몰수가 같지 않았다. 한편, 동일한 기간 동안 질소의 농도는 약 1.3 mol% 증가하였으며 그 증가된 농도는 소모된 산소와 배출된 이산화탄소의 농도변화량의 차이와 비슷한 값을 보였다. 따라서 질소의 몰분율 증가는 소모된 산소와 배출된 이산화탄소 간의 몰분율 차이에 의한 것임을 알 수 있었다. 본 연구에서는 기체의 조성 변화량을 정확히 측정하여 유정란의 부화과정 중 호흡현상을 설명할 수 있었다. Oxygen(<TEX>$O_2$</TEX>) consumption and carbon dioxide(<TEX>$CO_2$</TEX>) excretion of a fertile chicken egg during incubation were measured by a gas mass spectrometer. A closed sample chamber was developed to collect gas samples during the 20 days of artificial incubation of both a fertile and an infertile egg. After leaving an egg in the sample chamber for an hour, using a gas-tight syringe, samples of 2 mL of gas were collected from the closed sample chamber and analyzed using a gas mass spectrometer in 2~4 day intervals. The <TEX>$O_2$</TEX> consumption and <TEX>$CO_2$</TEX> excretion of chicken embryos increased rapidly after 10 days from the starting point of incubation. After 20 days, 23 mL of <TEX>$O_2$</TEX> was consumed and 16 mL of <TEX>$CO_2$</TEX> was excreted per hour. Throughout the whole period of incubation, concentration of <TEX>$O_2$</TEX> decreased 4.3 mol% and <TEX>$CO_2$</TEX> increased only 3.1 mole%, i.e., the mole of consumed <TEX>$O_2$</TEX> and the mole of excreted <TEX>$CO_2$</TEX> were not the same. On the other hand, during the same period, concentration of <TEX>$N_2$</TEX> increased about 1.3 mol% and the increased mole fraction of <TEX>$N_2$</TEX> was comparable with the difference (1.2 mol%) between the mole fraction of consumed <TEX>$O_2$</TEX> and excreted <TEX>$CO_2$</TEX>. Therefore, we can attribute the increase of <TEX>$N_2$</TEX> mole% to the difference of mole fraction between consumed <TEX>$O_2$</TEX> and excreted <TEX>$CO_2$</TEX>. In this study, through the analysis of gas, we could explain the respiration of a fertile chicken egg during incubation." @default.
