🍂 **Fall Weather & Your Horse’s Hydration** 💧
Cooler evenings and warm days can make it easy to overlook hydration. It is essential to provide clean, fresh water and monitor your horse’s water intake. To encourage adequate water consumption, it is important that horses receive enough salt.
🧂 Salt supports five important functions:
💧 Hydration: Sodium helps pull water into the bloodstream and maintain fluid balance during heat and exercise.
🧠 Nerve function: Sodium and chloride transmit electrical signals along nerves.
💪 Muscle contraction: Sodium helps trigger the processes that allow muscles to contract.
🥣 Digestion: Chloride is a key component of stomach acid (HCl), supporting protein digestion.
⚖️ Acid-base balance: Sodium and chloride help maintain normal blood pH, especially after sweating.
Salt Block vs. Loose Salt🧂
Horses generally prefer loose salt and will often voluntarily regulate their intake. Loose salt can provide a more reliable daily intake, while salt blocks are a convenient pasture backup.
Daily salt needs vary with size, workload, diet, and environment, with needs increasing after sweating and during warmer weather.
💧 Check your horse’s hydration by looking at their gums—they should be moist and pink, with a capillary refill time of less than 2 seconds.
