Abstract Objective To determine the effects of drugs with potential prokinetic effect through different mechanisms action (metoclopramide, cisapride, pyridostigmine, and capromorelin) on food consumption, fecal production, water intake, urine output in rabbits. Methods In a randomized, blinded, complete crossover control trial, 10 healthy New Zealand white rabbits ( Oryctolagus cuniculus ) received 5 treatments over period weeks between May August 2019. Fecal production (weight number...
