Fall Laminitis 🍂
Majority of horse owners understand that spring can be a risky time for horses prone to laminitis. Introducing our equine friends to their lush summer pastures slowly or incorporating limited grazing through grazing muzzles is a normal part of our spring routine. Did you know that fall also poses an increase risk for laminitis? Usually around September - October annually we see a spike in laminitis cases.
❓How does the fall season increase the risk for laminitis?
🌧️Overgrazed summer pastures often get a spike in growth with some fall rains - these short stressed pastures although short often stockpile sugars in their short stems after a rainfall.
🥶Lower daily temperatures, shorter day length and frosty evenings causes grass to also increase their sugar storage
❓What makes some horses more prone to laminitis than others?
⚖️ Obesity is strongly related to ‘Equine Metabolic Syndrome’ a condition that stimulates insulin resistance and systemic inflammation
👵 Cushings disease (elevated ACTH) seen in older horses increases sensitivity to sugars and more prone to laminitis
🏋️♀️ Lack of exercise/movement can make horses more prone to laminitis through weight gain and slowed metabolism.
❓How can I reduce my horses risk of Fall laminitis?
🩸Testing any suspect horses for cushings disease (ACTH) or insulin levels before fall and managing appropriately with medication and management changes
🌱 Avoid fall grazing on short stressed pastures after fall rains or frosts
🤿 Use a grazing muzzle where appropriate to reduce grass intake for overweight horses
🕦 Adjust management to avoid grazing during early mornings after a frost or rain
🐎 Keep your horses active and fit into the fall months
If you have any questions or concerns about fall laminitis, cushings or equine metabolic syndrome speak with your veterinarian about testing and managing strategies that are best for your individual horse!
