🌾 Hay vs Grass
One of the biggest feeding traps is treating the diet the same all year when the roughage isn't the same all year.
🌱 When there’s 'decent' green grass
Grass usually brings:
• more calories
• more protein
• more vitamins (especially A & E)
• more omega-3 fatty acids
• more moisture
Which is why in spring, horses often look shiny, feel “up”, and occasionally audition for the role of aerial trapeze artists.
With grass playing a big role in the diet you often need:
• less added vitamin E
• less added vitamin A
• no omega-3 supplement
• less/no added protein
• less/no calories added
And if the grass is 'decent' forget about them wanting to eat any hay!
🌾 When it's hay only
Hay isn’t a poor cousin of grass — it’s the stable, reliable version.
Its analysis doesn’t swing wildly with temperature, rain, time of day or whether mercury is riding in its Aquarius phase.
That predictability is gold!
In fact, if money/sourcing/lifting/netting were no object, many horses would do beautifully on a well-chosen hay-only diet because it gives us far more control.
However hay is almost certainly lower in:
• vitamin E
• vitamin A
• omega-3 fatting acids
• protein (depending on the hay)
• calories (depending on the hay)
So hay-only horses often benefit from:
• added vitamin E
• a source of vitamin A
• omega-3s such as flax oil (Equiflax)
• extra quality protein like H**p Promega
• thoughtful mineral balancing
• more attention to hydration
🧠 The real difference
Grass = more calories, more protein, more natural vitamins.
Hay = more consistency, more control, fewer surprises.
Neither is “right” or “wrong”.
They just need different support.
The supplement plan that was perfect during spring can be completely wrong once the paddock turns as beige as your aunty Karen.
Feeding horses isn’t about finding one magic diet.
It’s about matching the bucket to what the paddock is (or isn’t) providing — and enjoying the beautiful predictability that hay gives us when everything else in life is chaotic.
