⭐️ MORE INFO 👉 Grass sugar isn’t constant; this matters more than most people realise when horses are prone to laminitis.
It’s not just what they eat… it’s when that grass was growing and under what conditions.
🌱 Early morning isn’t always safe.
In spring (April - May), sugar levels can still be too high, even in the early morning.
☀️ Sunlight drives sugar production in the leaf.
Levels rise through the day, peaking in the afternoon.
❄️ Frost doesn’t increase sugar, it traps it.
When temperatures drop, the plant can’t move sugar into the roots. This gets worse over several cold, sunny days, as sugar builds up more and more in the leaf. So you might get away with grazing on the first morning after a frost but on the second or third morning it’s dangerous.
⚠️ Here’s why the sugar content matters:
Fluctuations in simple sugars cause insulin spikes. Repeated spikes raise horse baseline insulin. A high baseline insulin level is strongly linked to laminitis. This is why thinking about the sugar level in each mouthful of food and keeping it below 10%, combined with starch, works to stop those spikes and lower baseline insulin.
WHAT IS YOUR SOLUTION?
🌾 Hay is different. It’s cut when mature, so sugar levels are typically lower and ….. very stable. From our testing, over 80% of hay samples have low simple sugars and starch, which are suitable to feed without soaking (when the overall diet is balanced correctly).
👉 For more sensitive horses, a short soak (1–2 hours) may be helpful but you should try to test the hay to see, as soaking leaches valuable water soluble nutrients from the hay, as well as the sugar.
⭐️ Understanding how grass sugar changes is one of the most powerful tools you have to protect your horse’s health.
If you’re unsure whether your horse’s diet is safe, find a way to reduce or cut out grass in April and May (UK based). This could help save you heart break …. and a hole in your bank balance.
