Preparation
Wash thoroughly and feed fresh. Only offer very small amounts.
Quantity
A small handful (about half a cup) max, once in a while.
Notes
Avoid feeding to pregnant mares, growing foals, or horses with kidney issues due to high oxalate levels.
Nutritional Benefits
* High in Vitamin K, which is essential for healthy blood clotting.
* Good source of iron for healthy red blood cells.
* Rich in antioxidants that help reduce inflammation.
Safe Varieties
1. Fresh baby spinach leaves - Tender, mild, and easy to chew.
2. Mature spinach leaves - Safe, but slightly more bitter.
3. Chopped fresh spinach - Good for mixing lightly into a mash.
4. Cooked spinach - Loses some crunch but reduces oxalates slightly.
5. Frozen or canned spinach - Avoid, it turns to slimy mush that horses hate.
Feeding Guide
Average adult horse: One small handful mixed into feed occasionally.
Growing foals: Avoid. They need their calcium for bone growth.
Pregnant/Lactating mares: Avoid. Don't risk binding their calcium.
Positive Signs
* Sniffing and munching happily on a new flavor.
* Bright eyes and healthy blood counts.
* Normal digestion.
Negative Signs
* Long-term use can cause calcium deficiency, leading to weak bones.
* Refusing to eat their grain if you mix too much in.
Preparation Science
Spinach contains high levels of oxalic acid, which binds to calcium in the horse's gut and prevents it from being absorbed. This is why strict portion control is mandatory.
Enrichment Science
Offering diverse, leafy greens encourages natural sorting and sifting behaviors in the feed bucket, slowing down fast eaters.
Play Ideas
Easy: Sprinkle a few leaves on top of their grain like a garnish.
Medium: Hide a small handful of leaves deep inside a hay net.
Hard: Press a few leaves onto a wet, mashed banana smeared on the wall.
FAQ
Q: Will one handful hurt my horse?
A: Not at all! A small amount is perfectly safe for a healthy adult horse.
Q: Can I use it to boost my horse's iron?
A: Horses rarely need iron supplements. Talk to your vet before trying to fix a deficiency with food.
Alternatives
* Romaine lettuce is much safer for daily feeding and has zero oxalates.
* Kale is another dark green but causes gas, making it tricky too.
* Grass hay is always the safest, best source of green forage.
Risks & Disclaimer
Spinach is safe in very small pinches, but never feed it daily. The oxalates will rob your horse of calcium, which is dangerous for their bones.
