The autumn equinox and the hormone-led changes it brings for our horses
In Autumn, levels of adrenocorticotropic hormone (ACTH) naturally increase to encourage longer coat growth and the storage of fat to prepare the horse for the cold winter ahead. In “normal” horses, the subsequent rise in circulating insulin is well tolerated, but in horses that are insulin dysregulated the increase may push them over the edge and make them more prone to laminitis.
