Goat Feed Calculator β€” Hay, Grain & Minerals by Weight and Stage

Calculate daily hay and grain for goats by weight, breed, and production stage: maintenance, pregnant, lactating, growing kid, or breeding buck. Includes mineral and CDT vaccination recommendations.

Daily ration
  • Hay / forage: 3.5 lb
  • Grain / concentrate: 0 lb
  • Loose goat minerals: free-choice
  • Water: 1-3 gallons
Goats need goat-specific minerals (NOT sheep minerals β€” sheep minerals lack copper). Avoid moldy hay and excess grain (causes enterotoxemia).

How to use the goat feed calculator

  1. Weigh goat β€” Weight tape or scale; essential for accurate ration.
  2. Select breed + production stage β€” Maintenance, pregnant, lactating, growing, buck.
  3. Read hay + grain daily amounts β€” Output includes mineral recommendations.
  4. Provide goat-specific minerals β€” Free-choice, NOT sheep minerals (copper difference).

Frequently Asked Questions

How much should I feed my goat per day?

Baseline: 3.5 % of body weight in hay per day for maintenance. A 100-lb dairy goat at maintenance eats about 3.5 lb hay. Lactating does increase to 4.5 % (4.5 lb hay) plus 1 lb grain. Growing kids eat 2–3 % body weight in total feed, heavily supplemented with creep feed. Bucks during breeding season: 3.5–4 % body weight. Always free-choice water + goat minerals.

Can goats eat sheep minerals?

No. Sheep are copper-sensitive (toxicosis at levels goats require), so sheep minerals are copper-deficient. Goats need 12–18 ppm copper in their diet vs. sheep's 8–10 ppm. Feeding sheep minerals to goats causes chronic copper deficiency: faded coat (red goats turn orange), anemia, infertility, weak kids, and unhealthy hair. Use goat-specific mineral (Sweetlix Meat Maker, Purina Goat Mineral, ADM Alliance) β€” free-choice, loose (not blocks).

What is enterotoxemia and how do I prevent it?

Enterotoxemia (&ldquo;overeating disease&rdquo;) is caused by <em>Clostridium perfringens</em> types C and D. Sudden grain access, lush pasture access, or high-carb feed shifts allow the bacteria to proliferate and release fatal toxins. Prevention: (1) CDT vaccine annually + 4–6 weeks pre-kidding for does, (2) gradual grain introduction over 7–10 days, (3) never exceed 1 lb of grain per meal for adults, (4) provide free-choice baking soda for rumen pH buffering.

Can goats eat hay alone without grain?

Maintenance does and wethers can thrive on quality hay + minerals alone. Grain supplementation is needed for: lactating does, late-pregnant does (last 6 weeks), growing kids, finishing market goats, bucks during breeding, and recovery from illness. Good-quality hay (green, leafy, 14–16 % protein) with free-choice mineral meets basic needs for adult non-producing goats. Test hay to know protein + energy values rather than guessing.

What's the difference between dairy and meat goat feeding?

Dairy goats (Alpine, LaMancha, Nubian, Saanen, Nigerian Dwarf): feeding focused on milk production β€” lactating does get 4.5 % body weight in hay plus 1–2 lb grain/day based on milk yield. Meat goats (Boer, Kiko, Spanish): feeding focused on fast growth and muscle deposition β€” higher grain during finishing phase, creep feed for kids. Fiber goats (Angora, Cashmere): lower protein but consistent, targeted mineral supplementation for coat quality.

Do goats need copper boluses?

Many US goats benefit from copper oxide wire particle (COWP) boluses 2Γ— yearly β€” especially in areas with known deficiency or high-molybdenum soils. Standard dose: 1 gram per 22 lb body weight (adult goats). Over-supplementation can cause toxicity in sheep (if farm has both). Always work with your vet β€” blood/liver copper testing confirms whether supplementation is needed. Free-choice goat mineral alone is sometimes insufficient in deficient regions.
