U.S. Senate Document Number 264

In 1936, the U.S. Senate Document Number 264 stated that the grazing lands and crop lands of the USA had been depleted of minerals . Furthermore, this document stated that to supply the needs of man or animals it was necessary to supplement minerals.

" The alarming fact is that the grain and hay that we are now producing on millions of acres of land no longer contain enough minerals to provide our equine population with the necessary raw materials to sustain normal body functions."

" Plants, although able to produce vitamins and proteins, can not synthesize minerals if there are none in the soils."

" Our horses are continually exhibiting more evidence of mineral deficiencies, namely Osteoporosis, Osteochondritis dissecans (OCD), Osteoarthritis, Anemia, Aneurysms, Depression, Colic, nervous disorders (ie: Cribbing, Weaving, Stall Walking, Irritability), Cardio Myopathy, Lack of Stamina, Decreased Hormonal Production, Stunted Growth, and Failure to Produce Quality Hooves."
