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.
Calculator
- Hay / forage: 3.5 lb
- Grain / concentrate: 0 lb
- Loose goat minerals: free-choice
- Water: 1-3 gallons
How to use the goat feed calculator
- Weigh goat β Weight tape or scale; essential for accurate ration.
- Select breed + production stage β Maintenance, pregnant, lactating, growing, buck.
- Read hay + grain daily amounts β Output includes mineral recommendations.
- Provide goat-specific minerals β Free-choice, NOT sheep minerals (copper difference).
Goat feed targets by production stage
| Stage | Hay (% BW) | Grain | Protein % |
|---|---|---|---|
| Maintenance doe (open) | 3.5 % | None | 10β12 % |
| Early pregnancy | 3.5 % | Minimal | 12 % |
| Late pregnancy (last 6 wk) | 3.5β4 % | 0.5β1 lb | 14β16 % |
| Lactating doe | 4.5 % | 1β2 lb per 3 lb milk | 16β18 % |
| Growing kid (weaned) | 2.5β3 % | 0.5β1.5 lb | 16β18 % |
| Finishing market goat | 2β2.5 % | 1.5β2 % BW | 14β16 % |
| Breeding buck | 3.5β4 % | 0.5β1 lb seasonal | 12β14 % |
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 2β3 % body weight in total feed, heavily supplemented with creep feed. Bucks during breeding season: 3.5β4 % 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 12β18 ppm copper in their diet vs. sheep's 8β10 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 (“overeating disease”) 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 + 4β6 weeks pre-kidding for does, (2) gradual grain introduction over 7β10 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, 14β16 % 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 1β2 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.
