White Substance on Horse Tendons: Causes & What It Means

Question

thick substance on hor   hello sir, why i found a white thick substance on a racehorse tendons after the groom removed the polo wraps wrapped up on its forelegs. the rider told me that he gave a blow out to the horse from 5 furlongs. can that be foamy sweat on the horse tendons?

Answer
Yes, I believe this is most likely sweat without actually seeing the foam first hand. It could also be foam from soap residue either left on the polo wrap or even shampoo from the horse itself if a thorough rinse after bathing or laundry was not conducted.
