Introducing Your Horse to Grass: 2025 Vet Routine by Dr Duncan Houston 🐎🌿

Welcome! I’m Dr Duncan Houston, veterinarian and founder of AskAVet.com. Spring is a beautiful time, but new grass can pose hidden risks to equine digestion and metabolism. In this 2025 vet guide, we'll walk through a safe, step-by-step transition to grazing—covering hand-grazing, turnout plans, pasture readiness, health monitoring, and long-term pasture management. Let’s support your horse’s well-being! 🩺✨

🌿 Why a Careful Transition Matters

Spring grass is lush and tasty but also high in non-structural carbohydrates (NSCs) like fructans and sugars. Sudden intake can lead to colic, laminitis, or hindgut upset. Studies show microbial shifts in the gut within 4 days of pasture access, with risks increasing dramatically if changes are rushed :contentReference[oaicite:3]{index=3}.

🚦 When to Start Grazing: Pasture Readiness

  • Wait until grass is at least 6 inches (15 cm)—this ensures root and plant maturity :contentReference[oaicite:4]{index=4}.
  • Soil should be firm to minimize hoof damage.
  • Ensure vaccinations/deworming are current—preparing for herd turnout :contentReference[oaicite:5]{index=5}.

🧍‍♀️ Step-by-Step Introduction Plan

Begin with hand‑grazing in a drylot or controlled paddock:

  1. Days 1–3: 15–20 minutes of hand grazing each session :contentReference[oaicite:6]{index=6}.
  2. Then increase by 15–30 minutes every 3–4 days, depending on the horse's response :contentReference[oaicite:7]{index=7}.
  3. By 3–4 hours per day, maintain that for 1–2 weeks before full turnout :contentReference[oaicite:8]{index=8}.
  4. Turnout just after hay/grain: reduces hunger-driven overeating :contentReference[oaicite:9]{index=9}.

🐎 Grazing Plans and Pasture Management

  • Rotational grazing: Divide pasture into smaller paddocks, resting areas in rotation to prevent overgrazing :contentReference[oaicite:10]{index=10}.
  • Stock at ~2 acres per 1,000 lb horse to ensure forage supply :contentReference[oaicite:11]{index=11}.
  • Measure forage height regularly—maintain 6–8 inches to support regrowth :contentReference[oaicite:12]{index=12}.
  • Use grazing muzzles on metabolic risk horses during early spring overflow.

⚠️ Monitor Health Closely

  • Watch for grass founder/laminitis signs—reluctance to walk, hoof heat.
  • Check manure regularly—diarrhea can signal microbial imbalance.
  • Track hydration and weight—grass is high moisture, might reduce intake/water.
  • Observe herd interactions—ensure shy or subordinate horses are eating well :contentReference[oaicite:13]{index=13}.

🥕 Feeding During Transition

  • Continue hay or forage feeding daily in addition to pasture intake :contentReference[oaicite:14]{index=14}.
  • Don’t change grain or supplements during this time.
  • Provide salt and electrolytes as needed—especially if grazing causes looser stools.

🛠️ Common Challenges & Solutions

Challenge Solution
Rapid weight gain or metabolic issues Use grazing muzzle, slow intake, monitor weight
Overgrazed patches or weeds Rotate paddocks, rest pasture, reseed
Colic or diarrhea Pause grazing, bolster hay, vet check
Aggressive herd behavior Separate vulnerable horses during turnout

🌾 Long-Term Pasture Best Practices

  • Implement ongoing rotational grazing year-round.
  • Fertilize and test soil for pH and nutrients.
  • Reseed bare spots with horse-safe grasses.
  • Keep fencing, water, shelters, and shade maintained.
  • Collect/managing manure to reduce parasite exposure and improve forage quality :contentReference[oaicite:15]{index=15}.

✅ Quick Recap – 2025 Vet Essentials

  1. Wait for grass to reach 6″—pasture is ready.
  2. Start hand-grazing 15–20 min for 3–5 days.
  3. Gradually increase turnout every few days.
  4. Maintain hay & regular feed during transition.
  5. Use grazing muzzles/measures for metabolic horses.
  6. Monitor weight, behavior, manure, hydration daily.
  7. Adopt rotational grazing & pasture rest long-term.
  8. Use AskAVet.com for support, grazing schedules, and monitoring tips!
