“Now that spring is here, we need to take it slowly when transitioning any of our horses from hay to pasture,” says equine nutritionist Juliet M. Getty, Ph.D. “And for those of us with insulin resistant horses,” she adds, “we may also need a dose of patience.”
The first spring sprouts are actually lower in sugars and starch (non-structural carbohydrates—NSC) because they use all that energy to promote their own rapid growth. But horses crave fresh grass and will eat volumes of it, making their overall NSC consumption really high—dangerously high for horses who are overweight, cushinoid, or who have experienced insulin-related laminitis.
To be safe, here are the rules:
There is no exact “best time” to turn out your horses on pasture. Generally speaking, it’s safest before dawn, until approximately 10:00 am, and then again at night, starting at around 11:00 pm. Start slowly, offering hay when horses are not on fresh grass.
Finally, test your pasture! Yes, testing is not only for hay. It will take the guesswork out of knowing which times are best.
