Study: Hungry Ponies May Want To Hibernate

If you've ever jokingly referenced having “the urge to hibernate” when the weather turns cold, you're not alone! Interestingly, ponies may feel the same way—especially if they don't have enough to eat.
Animals that hibernate experience a decrease in both their heart rate and their body temperature when winter weather hits; their metabolism also slows. Drs. Lea Brinkmann, Martina Gerken, Catherine Hambly, John Speakman and Alexander Riek created a study to see if ponies had similar physiological adaptations.
The research team used 10 Shetland ponies and studied them through the year, measuring each pony's vital signs and using blood tests to check metabolic rates. During winter months, they fed all 10 ponies a diet that met 100 percent of their maintenance needs. They then divided the ponies into two groups: one group received meals that met tall their metabolic needs and the second group was put on a diet that provided only 60 percent of the pony's energy requirements.
