RE-SORB® is 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.
Dosage and Administration:
: Add the contents of 1 packet (both sides) to 2 quarts of warm water. Stir until dissolved.
Feed 2 quarts of RE-SORB® solution made up as directed, twice daily for 2 days (4
feedings). No milk or milk replacer should be fed during this period. For the next 4 feedings (days 3 and 4),
use 1 quart of RE-SORB® solution mixed together with 1 quart of milk or milk replacer. Thereafter, feed
Newly Purchased Calves:
Feed 2 quarts of RE-SORB® solution made up as directed instead of milk as the first
feed upon arrival. For the next scheduled feeding, use 1 quart of RE-SORB® solution mixed together with 1
quart of milk or milk replacer. Thereafter, feed as normal.
RE-SORB® should not be used in animals with severe dehydration (down, comatose, or in a state
of shock). Such animals need intravenous fluids since oral therapy in these cases is too slow. A veterinarian
should be consulted in such severely scouring calves or in cases requiring antibacterial therapy.
Antibacterial therapy is often indicated in bacterial scours due to E. coli and/or Salmonella. RE-SORB® does
not contain antibacterial agents.
Adequate colostrum intake during the first 12 hours is essential for healthy, vigorous calves.
RE-SORB® is not nutritionally complete if administered by itself for long periods of time. It should not be
administered beyond the recommended treatment period without the addition of milk or milk replacer.
For use in calves only.
