⛈️ Stormy Weather Warning 🍁
⚠️ Storm Austen is expected to increase seed drop and spread Sycamore seeds with the strong winds‼️ Atypical Myopathy Warning ‼️
🌳 Atypical myopathy is caused by horses eating sycamore seeds that fall onto pasture in Autumn and Winter, and their germinating seedlings in Spring.
☠️ Seeds and seedlings contain the toxin hypoglycin A (HGA) which slows or stops energy production in muscle and heart.
🐴 Symptoms include reluctance to move, depression, low hanging head, dark brown or red urine, muscle trembling and colic like symptoms without a loss of appetite. These symptoms can rapidly progress to collapse and difficulty breathing.
⚠️ Atypical myopathy is fatal in up to 80% of cases. Rapid diagnosis is essential.
‼️ Prevention tips
🌟Provide supplementary forage during Autumn away from the tree line.
🌟Clear fallen sycamore leaves and seeds from grazing areas.
🌟Remove horses from affected grazing areas.
🌟Check neighbouring areas for high risk plants/seeds as some ‘helicopter’ seeds can travel up to 200 yards.
🌟Test for the presence of HGA in your own horses’ pastures
