Effect of ketoprofen on Escherichia coli heat-stable enterotoxin-induced diarrhea of calves.
Additional Document Info
To evaluate the effect of ketoprofen on fecal output during secretory diarrhea, 16 calves were given approximately 200 micrograms of heat-stable Escherichia coli enterotoxin by suckling on 2 occasions. On one day, treatment was not administered. On the other day, either 3 mg of ketoprofen/kg of body weight (n = 8) or 6 mg of ketoprofen/kg (n = 8) was administered 1 hour before and 3 hours after administration of enterotoxin. Fecal output was no different after 8 or 24 hours from calves given 3 mg/kg, but fecal output was less at 8 hours and 24 hours for calves given 6 mg/kg (P = 0.0588), compared with the control day.
