Re: [RC] Core Temps ( Won't hurt?) - Truman PrevattJohn Teeter wrote:That was 15 years ago - you expect me to remember ;-) ? The issues with cooling of horses is their body mass (volume) to surface area ratio is much larger than that for humans. Since cooling takes place for the most part at the surface - horses are at a distinct disadvantage compared to say humans when the weather turns humid. Gayle's talk was about the results of the electrolyte loss studies she had done. She has a very large database of horses and the physics of heat dissipation was introductory to this talk. The one thing I do remember was with horses "it is the humidity stupid" is very appropriate since one of the rides with a large electrolyte loss across the board was a ride where the temp was in the 40's but the humidity was 100%. A horse can quickly run its core temp up to 106 at 40 degrees ambient if there is no evaporative cooling. An interesting aside on a ride I ran in '97 we have very similar conditions - in the 50's but 100% humidity before a cold front moved in. It was a demolition derby. The treatment barn looked like a MASH unit. Horses were thumping left and right. We went through between 240 and 300 liters of fluids - all to treat dehydration and tie ups. The treatment vet and I got about one hour of sleep on Saturday night. We sent one horse to UF clinic after we got him stable enough to be transported and it was touch and go for quite a while on him. He did recover. It was 8:30 AM - that's about all I recall, except a comment from Maggie Price asking for a bottom line formula for electrolyting. When Gayle responded that there isn't any - it all depends on the horse and the day. Maggie replied, "even after all these years and all this work, that's all you can tell us?" Seems that little has changes since then.
