Abstract
In the trials reported in this paper the only instances in which the feeding of thyroprotein resulted in an increased growth rate in swine were those in which the level of thyroprotein fed per unit of body weight decreased as the animals grew larger. (Trial I, Lot V; Trial III, Lots II and V). The feeding of thyroprotein to hogs on pasture in no case stimulated growth rate and in one instance (Trial II. Lot III) depressed growth rate significantly. Animals which consumed the highest levels of thyroprotein, per unit of body weight, had anterior hypophyses with the lowest assays of thyrotropic hormone.
