36 Sprague-Dawley rats were subjected to stress by immersion, erratic photoperiod and crowding for 28 days. Control and experimental animals were sacrificed and the thymus, spleen, adrenals, testis, and pituitary were removed and their weights were recorded as a ratio of organ weight to body weight. The pituitary was the most accurate measure of stress according to Z scores.
