Feeding horses prone to laminitis:
The summer grazing season has begun in earnest. Many of our clients have changed from winter to summer grazing and the fields are well covered this year.
Sunshine means more photosynthesis which means more sugar production by the grass. After rainfall, short new growths can be very rich, and your horse is likely to notice them before you do! Mature grass that has been topped or not gone to seed is higher in fibre and lower in sugar than young grass but can still be problematic if your horse eats too much.
Limiting grazing and increasing exercise to improve metabolism can be key in reducing the risk of laminitis.
Grazing muzzles are a great way to reduce grass intake whilst still allowing your horse or pony to go out and socialise, but they need to be checked regularly to make sure they stay on without causing rubbing and discomfort to the face. Using track systems or strip grazing can help to limit grass intake even if you can’t get your horse or pony to keep a muzzle on.
If your horse needs to come off the grass to manage their weight and laminitis risk aim to give them 1.5% of their bodyweight in hay over 24hrs. Soaking the hay for around 3 hours will reduce the sugar content, just be careful about where you dispose of your very sugary wastewater! Split the hay between several small-holed nets and place it in different areas to slow down consumption.
If your horse cannot go on grazing for a prolonged time, they may benefit from a good quality balancer to maintain normal nutrient balance.
Our team is always happy to discuss management with you if you would like further advice on diet for laminitis prone horses.
