"Pour qu’un mammifère puisse survivre, la température interne est maintenue dans une fourchette assez étroite. Si cette température interne dépasse ces limites minimales ou maximales, les réactions chimiques des cellules ne fonctionnent plus correctement. Voire elles ne fonctionnent plus du tout. Les fluctuations en dehors de la fourchette de températures normales entraîne des problèmes de santé pouvant aller jusqu’à la mort de l’animal. Les chevaux adultes maintiennent leur température interne autour de 38°C. Les poulains en croissance et les juments en gestation ou allaitantes ont des températures internes normales plus élevées. (Hines, 2004)."

"Cold weather often seems to trigger laminitis - we usually see an increase in laminitis cases as soon as the weather turns cold (snow/ice/frost) each winter.
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 that's not exactly correct - they shouldn't graze the grass until there has been a return to night time temperatures above 5'C and/or overcast weather."

"Reasons laminitis might occur in the autumn include:
Seasonal changes in hormones - horses have a seasonal rise in hormones [that increase insulin resistance, thought to help horses prepare for winter food shortages].
Autumn flush of grass as wet and warm weather encourage growth.
Owners often increase feed but may reduce exercise as days become shorter/weather less pleasant.
Rugging may reduce calories used keeping warm."
