Heat stress is created when livestock cannot expel enough heat to maintain their core body temperature for optimal production and health. The temperature-humidity index (THI) is a number that combines humidity and temperature to correlate with the amount of heat stress an animal experiences.

A good hoof maintenance schedule is one of the most important contributors to a successful dairy operation. Foot health has a direct impact on milk production, and ignoring lameness in a herd can be far more costly than the price of a hoof health program.
