Introduction
Proper nutrition is the cornerstone of equine health and performance. For professional stables, standardized feeding techniques ensure consistent care, optimal health, and peak performance. This guide provides detailed recommendations on feed types, portions, frequency, and essential nutrients for horses.
Recommended Feed Types
Horses are herbivores with a digestive system adapted to continuous grazing. The foundation of any diet is high-quality forage, such as grass hay or alfalfa. Additional feed types include:
- Forage (Hay/Pasture): Should make up at least 50-70% of the diet by weight. Choose hay based on maturity and protein content.
- Concentrates (Grains): Oats, corn, and barley provide energy. Use pelleted or extruded feeds for balanced nutrition.
- Supplements: Provide vitamins, minerals, and protein as needed. Commercial balancer pellets are common.
- Soaked Beet Pulp: High-fiber energy source, good for weight gain or hydration.
Portion Sizes and Daily Caloric Needs
Daily feed intake depends on body weight (BW), age, and workload. A typical horse consumes 1.5-2.5% of its BW in dry matter per day. Use the table below as a guide:
| Horse Type | Body Weight (kg) | Daily Hay (kg) | Daily Grain (kg) | Daily Calories (Mcal) |
|---|---|---|---|---|
| Maintenance (light work) | 500 | 7.5-10 | 0-2 | 16-20 |
| Moderate work | 500 | 7.5-10 | 2-4 | 20-24 |
| Intense work | 500 | 7.5-10 | 4-6 | 24-30 |
| Pregnant mare (late) | 550 | 8-11 | 2-4 | 22-26 |
| Lactating mare | 500 | 10-12 | 4-6 | 28-34 |
| Weanling (6 mo) | 200 | 3-4 | 2-3 | 12-16 |
Adjust based on body condition score (BCS 1-9). Ideal BCS is 5-6.
Feeding Frequency and Schedule
Horses should be fed multiple times daily to mimic natural grazing. A typical schedule:
- Twice daily: Suitable for most horses. Feed hay and grain in two equal meals (e.g., 7am and 5pm).
- Three to four times: For horses with high metabolic demands, ulcers, or laminitis risk. Smaller, more frequent meals reduce starch overload.
- Free-choice hay is ideal when possible, using slow-feed hay nets to extend eating time.
Always feed grain after hay to slow intake and prevent colic.
Essential Nutrients
Horses require six classes of nutrients: water, carbohydrates, protein, fat, vitamins, and minerals.
- Protein: 8-16% of diet. Grass hay typically 6-10%, alfalfa 15-18%. Growing horses and lactating mares need higher protein.
- Carbohydrates: Primarily fiber (hay) for slow-release energy. Starch (grain) for quick energy; limit to 2g per kg BW per meal to avoid colic.
- Fat: 3-8% of diet. Vegetable oils (corn, canola) add calories without sugar, ideal for hard keepers.
- Vitamins: A, D, E, K (fat-soluble). Fresh pasture provides Vitamin A; sun exposure provides D.
- Minerals: Calcium, phosphorus, magnesium, potassium. Provide a mineral salt block (loose preferred) and balance calcium:phosphorus ratio (ideally 2:1).
Toxic Foods and Ingredients
Avoid these harmful substances:
- Moldy hay or grain can cause colic or respiratory issues.
- High-starch grains (e.g., corn) fed in large amounts lead to laminitis.
- Lawn clippings can ferment rapidly, causing colic.
- Certain weeds: Ragwort, red maple leaves, bracken fern, yew. Remove from pastures.
- Avocado, chocolate, caffeine are toxic to horses.
- Sudden dietary changes disrupt gut flora. Transition over 7-10 days.
Water Intake Recommendations
Horses need 5-10 gallons (20-40 liters) of fresh water daily. Factors: temperature, workload, diet. Provide free access at all times. In winter, heated water buckets encourage drinking. Signs of dehydration: capillary refill time >2 sec, skin tenting, dry gums.
Beneficial Supplements
Consider these based on individual needs:
- Electrolytes for heavy sweating (Na, K, Cl). Use a balanced product after exercise.
- Probiotics and prebiotics support gut health during stress or antibiotic use.
- Joint supplements (glucosamine, chondroitin, MSM) for older or working horses.
- Vitamin E for horses on hay-only diets (especially if not on pasture).
- Biotin for hoof quality (10-20 mg/day).
Always consult a veterinarian or equine nutritionist before adding supplements.
Feeding Differences by Age
Nutritional needs change throughout life.
Foals and Weanlings
- Mare's milk first 2-3 months. Creep feed (12-16% protein starter) from 2 weeks.
- Wean at 4-6 months. Feed high-quality hay and foal concentrate (14-16% protein).
- Frequent meals (3-4 times daily) to avoid overeating and bone issues (DOD).
Adult Horses (4-15 years)
- Maintenance: good hay, mineral balancer. Adjust grain for workload.
- Monitor BCS monthly. Overweight horses: restrict grain, use low-NSC hay.
Senior Horses (15+ years)
- Dental issues: soaked hay cubes or complete feeds (easy-to-chew).
- Higher protein (14-16%) to maintain muscle.
- Fat added for energy. Senior feeds with prebiotics.
Signs of Healthy vs. Poor Diet
Healthy Diet Signs:
- Shiny, smooth coat.
- Clear eyes and pink mucous membranes.
- Consistent manure (fecal balls, golden-brown).
- Good body condition (ribs easily felt but not visible).
- Energetic but calm demeanor.
Poor Diet Signs:
- Dull, rough hair coat.
- Lethargy or excessive nervousness.
- Weight loss or obesity.
- Diarrhea or dry manure.
- Laminitis (reluctance to move, hoof heat).
- Recurrent colic or respiratory issues.
If you observe these signs, consult an equine professional. Adjust diet gradually.
