Rex A. Ewing grew up in northeastern Colorado’s Platte valley, where he spent most of his time looking after the family’s herds of Charolais cattle and Thoroughbred horses. He learned early about the importance of proper feeding since, in addition to the purebred stock, the Ewing Ranch operated an experimental feedlot for horses, cattle and sheep, where his father, John, tested the efficacy of different feeds and additives.
Following college, Rex returned to life on the ranch, managing the horse operation and assisting his father in the family’s horse nutrition business. When John Ewing died in 1990, Rex became president and CEO of the John Ewing Company, a world-renowned producer of horse nutrition products. Combining his years of common-sense experience with the scientific particulars of horse nutrition, he formulated a number successful products, wrote regularly for horse publications, and talked to thousands of horse owners about their nutrition related problems.
After leaving the family business in 1997, Rex wrote the first edition of Beyond the Hay Days. Since then, he has maintained his contacts and followed the industry closely. The updated and expanded 2nd edition was released in 2003.
