❄️Laminitis & frost ❄️
Finally, the weather has taken a bit of a cold turn, with the first frost at TCEH last week.
Frosty weather may be beautiful but sunny days with cold frosty nights cause sugars to accumulate in the grass. People often think that laminitic horses shouldn't graze frosty grass until the sun has melted the frost, but actually they shouldn't graze the grass until there has been a return to night time temperatures above 5'C and/or overcast weather.
During sunny weather grass makes and stores sugars, then at night when grass is able to grow these sugars are used up. However, when environmental conditions such as low temperatures (below around 6'C), lack of rainfall or poor fertility prevent growth, sugar levels can continue to accumulate in the grass, making it unsuitable for horses and ponies with insulin dysregulation and increasing the risk of laminitis.
If your horse is prone to laminitis, please be careful when they are grazing in the winter and be vigilant for signs of laminitis, including a stiff gait, lameness or a rocking back stance. If you notice these signs, please take your horse off the pasture into a deeply bedded stable and call us.
