Daily feeding schedule and housing on incidence of activity-stress ulcer.
In Experiment 1 the number and size of ulcers resulting from exposure to an activity-stress procedure were inversely related to the length of the pre-stress experience with either 1 hr or 2 hr daily feeding schedules. In Experiment 2, rats housed in group cages during the pre-stress period were more vulnerable to the ulcerogenic effects of the activity-stress procedure. A pellet food or powdered food treatment condition failed to provide significant group differences. Vulnerability to stress-ulcer is discussed in terms of the disparity of the environmental conditions between the acclimation period and the activity-stress period.
