Abstract
Rats were housed in activity cages and fed 1 h daily. When these rats died, wet and dry weights were obtained for adrenals, spleen, liver, kidney, heart, stomach rumen, and stomach body. Most activity rats, as compared to food-yoke control and home-cage control rats, had lesions in the glandular stomach. Adrenal and heart weights suggested that activity rats had been subjected to some degree of stress. Characteristic starvation effects, such as rumenal lesions and edema of stomach tissue, were not observed in activity rats.
