Abstract

Several alternative methods are looking for animal welfare in veterinary medicine teaching. Those methods aim to replace live animals, impairing learning to the students. This papers’ objective was to quantify the intestinal resistance changes in dogs’ cadavers during fixation up to 4 months in a 10% formaldehyde solution and conservation in 30% sodium chloride solution. Three jejunum samples of eight dogs’ cadavers were collected and analyzed at 0, 30, 60, 90, and 120 days. Biomechanical traction test values from the jejunum and control group were compared, determining similarities, which could justify the use of these cadavers in surgical techniques.
