eSummer is all about energy levels at their highest. To support the energy demands, it's about keeping the heart toned, the blood purified and circulation regulated. June means the first hay cut; July/August it's high summer and hot! With those humid muggy conditions, pasture allergens are at their highest as well with the wet air holding more particles. Horses can also lose substantial minerals in sweat, so keep adding quality sodium to the feedbowl - studies show that horses will voluntarily consume around 50g of sodium/day if made available. Horses don't store sodium, potassium, or chloride in their tissues from one day to the next so electrolyte supplementation is essential when horses sustain high sweat losses.
