Think Hydrate paste is the syringe format of Brinicombe's electrolyte formula — a 30ml single dose for competition and travel days. The reason to keep pastes in the float is simple: a horse away from home often will not eat up, and a syringe goes in regardless.
Electrolytes only work with water. Dosing salts into a horse that is not drinking makes things worse, not better. Offer water before and after, and if the horse is refusing to drink at a show, that is worth taking seriously rather than dosing around.
For everyday use through a hot or busy stretch, the 5L buffered liquid is the format built for daily feeding.
Dosing instructions and the full ingredient list are on the syringe. If you compete, check the ingredients against the current prohibited substances list for your discipline.
