Estimate daily forage and grain amounts as body-weight percentages.
Horses eat roughly two percent of their body weight in forage daily, with grain added only when work or condition demands. Forage is the foundation of horse nutrition, and underestimating hay needed leads to colic risk and surprise winter costs.

Feed = horse weight x daily percentage; forage/year = daily x 365 / 1000
