In the 1920s the term cosmic rays was coined by Robert Millikan who made measurements of ionization due to cosmic rays from deep under water to high altitudes and around the globe. Millikan believed that his measurements proved that the primary cosmic rays were gamma rays, i.e., energetic photons.

In summary, high quality perennial grasses can fit well in the rations of high producing dairy cows.
