Silos have been used since very early times in one form or the other, and probably the first we have ever heard of are traceable back in ancient history to the Syrians, who had pits in the ground for the storage of animal feed. These pits have been used in various parts of the Old World ever since and have also been used in the United States. The pit does not give the best results.

In order to overcome these defects we soon began to see silos erected above ground. Cement, brick, tile and wood were used as building material, with various results. The industry developed rapidly and soon demonstrated what was necessary to keep the silage pure, sweet, clean and succulent. Science and research have helped, until now we can produce silos that will keep this green fodder in a sweet and succulent state until the owner is ready to use it.
