The magnetic field effect affecting on the metallic chemical components of egg shell as demonstrated for breeding chicken.
The chickens were raised under fixation of the permanent magnet (80 mT) and the effect of extra magnetic field, which affects on the content of the several inorganic chemical elements of egg shell, was investigated by X-ray fluorescence spectroscopy. From 3 days after fixing the magnet, the relative concentration of Ca begun to increase. After 10 days, the relative contents of Ca were decreased, while conversely the contents of K were increased. Though there was a linear relationship between Ca content and P content in inner layer of chicken egg shell, the relationship was greatly hindered by applying the static magnetic field. The experimental result suggests that both Ca and K ion transport can be perturbed by addition of extra magnetic field in the incubation processes of chicken egg, and that Ca, P and K ions play the important role in egg shell formation.
