A palatable concentrated electrolyte gel which can be mixed with milk for calves to maintain acid/base, electrolyte and fluid balance in diarrhea conditions. It does not interfere with the coagulation of the milk in the abomasum, which is important for the calf. By offering the palatable milk/Rehydion solution, the calf drinks more and recovers faster. Weight loss is reduced, the local immune system of the intestine is strengthened and any intestinal damage heals faster.
