THE ROLE OF GE­OG­RA­PHY

EQUUS - - Tack & Gear -

As a gen­eral rule, the more green grass a horse eats, the less likely it is that he will be­come de­fi­cient in vi­ta­min E. And the prob­a­bil­ity that he may not get enough de­pends, at least in part, on where he lives. “Here in North Carolina we are able to graze pas­ture nearly year-round, most years,” says Paul Si­cil­iano, PhD, of North Carolina State Uni­ver­sity. “We’ve found some sea­sonal changes in mares, but their vi­ta­min E sta­tus re­mains very good with­out sup­ple­men­ta­tion.” In con­trast, horses in north­ern cli­mates with shorter grow­ing sea­sons or in desert ar­eas, who are fed more dried for­age, may need to have vi­ta­min E added to their di­ets.
