The unique formulation of McCauley’s Hydrolyte encourages drinking and facilitates rehydration. Equine sweat is hypertonic, meaning the level of electrolytes in sweat is greater than that in blood. As a result, even though horses are dehydrated, they may lack the desire to drink.
When added to drinking water, Hydrolyte provides a more consistent taste and smell to different water sources. This is useful when horses are temporarily relocated (e.g., shows, events, etc.).
Add 1 to 4 oz. of McCauley's Hydrolyte per bucket of water (a typical water bucket for horses is 5-gallons) or top-dress 1 oz. per lb. or more of feed daily for an average-size riding horse (1,000 to 1,200 lbs.).
In preparation for intense competition, increase the level of McCauley's Hydrolyte gradually the week prior to the event, such that the horse will receive at least 4 oz. per day a few days prior to, during and after the event.
Daily recommendations may be increased or decreased depending on sweat loss, which is affected by intensity of exercise, environmental conditions (e.g., heat, humidity), body size and/or stress.
To promote drinking, McCauley's Hydrolyte should be added to a minimum amount of feed. Make sure fresh, clean water is available for the horse to drink.
Of Note: McCauley’s Hydrolyte is hydroscopic, meaning it has a high affinity for water. As such, this product will absorb moisture and clump if exposed to air too long. If this occurs, the product is still usable and can be crumbled to mix with feed or dissolved in water with stirring. To minimize clumping, reseal the pail after each use.
