A readily absorbed source of fluids and electrolytes. It is a convenient and effective means of increasing absorption of water, energy sources, and electrolytes. Re-Sorb is indicated for use in the control of dehydration associated with diarrhea (scours) in calves, including veal calves. Re-Sorb may be used by the livestock owner as an early treatment at the first signs of scouring. It may also be used as follow-up treatment for the dehydrated calf following intravenous fluid therapy. Re-Sorb, because of its ready source of fluid and electrolytes, makes it an ideal first feed (upon arrival) for newly purchased or severely stressed calves.
