Daily dry matter intake as percentage of body weight varies by species, production stage, and forage quality.
DMI (lb/day) = Body Weight × DMI % (cattle ~2–2.5% BW)Multiply per-head requirement by inventory. Adjust for gestation, lactation, and growth phases.
Daily Feed = DMI × Head Count; Annual = Daily × Days on FeedRound bales 800–1,200 lb; small squares 40–60 lb. Use actual bale weight from scale.
Bales = Total Hay (lb) ÷ Bale Weight (lb)Updated: July 2026
1,200 lb cows × 2.5% DMI = 30 lb/day × 30 head = 900 lb/day × 120 days = 108,000 lb ≈ 90 round bales at 1,200 lb.
1,000 lb horses at 2% DMI = 20 lb/day each = 200 lb/day hay. 5 months = 30,000 lb.
Finishing cattle on high-grain ration: 2–2.5% BW dry matter with 80% concentrate — calculate grain separately from roughage.
Plan feed purchases and storage for cattle, horses, sheep, and goats. Enter animal count, average body weight, and feed rate as percent of body weight or fixed pounds per head to get daily and seasonal feed totals.
