NIR spectra of poultry eggs at different storage days ranging from 0 to 21.

660 spectral curves with wavelengths between 740nm to 1070nm at a spectral resolution of 1 nm were obtained using a handheld SCiO NIR spectrometer. Spectral curves correspond to 22 days of continuous monitoring, with 30 shell intact brown poultry eggs. Eggs were collected from a flock of 20.000 hens of the strain H&N with 49-52 week-old. Hens were housed in stacked cage system, and were fed with a standard ration without the use of laying egg promoters.本数据集共包含660条光谱曲线，光谱波长范围为740nm至1070nm，光谱分辨率为1nm，数据通过手持式SCiO近红外（NIR）光谱仪采集获得。所有光谱曲线均来自22天的连续监测，监测对象为30枚完整蛋壳的褐壳家禽蛋。这些鸡蛋采自20000只H&N品系、周龄为49至52周的蛋鸡群。蛋鸡采用层叠笼养系统饲养，饲喂标准日粮，未使用产蛋促进剂。
