The importance of feeding electrolytes in winter

Feeding electrolytes to horses in winter is important for several reasons. Electrolytes are essential minerals that play a crucial role in maintaining proper bodily functions, including nerve and muscle function, hydration, and maintaining the balance of fluids and pH levels. In cold weather, horses may face specific challenges that can increase their need for electrolytes. 

  • Hydration: Cold temperatures can decrease a horse's water intake, leading to dehydration. Dehydration can impair the horse's overall health and performance. Electrolytes help stimulate the horse's thirst response, encouraging them to drink more water and stay adequately hydrated. 
  • Sweat Loss: Even in winter, horses can still work up a sweat during exercise or when rugged heavily. Sweat contains electrolytes, particularly sodium, potassium, and chloride. Replenishing these lost electrolytes is important to maintain the horse's electrolyte balance. 
  • Feeding Hay: During winter, horses may consume more hay, which is low in sodium compared to fresh pasture. This can result in an imbalance of electrolytes, particularly sodium. Supplementing with electrolytes can help ensure the horse's sodium levels are adequately maintained. 
  • Electrolyte Imbalances: Changes in diet and water consumption patterns during winter can disrupt the horse's electrolyte balance. Imbalances can lead to issues such as muscle cramps, fatigue, poor performance, and even metabolic disorders. Providing a balanced electrolyte supplement can help prevent these problems. 
  • Stress and Immunity: Cold weather, stabling, and other factors associated with winter can cause stress in horses. Stress can weaken the immune system, making horses more susceptible to illnesses. Electrolytes, particularly magnesium and zinc, are vital for supporting immune function and reducing the negative effects of stress.

When supplementing with electrolytes in winter, it's essential to choose a product specifically designed for cold weather conditions. Some electrolyte supplements are formulated to be palatable in cold temperatures and may have additional ingredients that support respiratory health or provide antioxidants to combat oxidative stress. OsmoPlex is a specific blend of minerals designed to support osmotic balance and normal cellular pH. There is approx 50% Sodium Chloride (salt) in every 80g daily dose of OsmoPlex and we recommend that OsmoPlex is fed all year round.
