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.
