Abstract
The pituitaries from steers fed for 125 days on rations varying in level of protein and carotene were assayed for thyrotropic hormone content. No effect of ration on thyrotropic hormone content of the pituitary glands was found. One lot of steers to which 10 mg. diethylstilbestrol daily per steer was included in the ration showed thyrotropic hormone content of the pituitary glands not altered by the hormone-like material.
