Effect of Methyl Thiouracil and Thiouracil in Swine¹

New Jersey Agricultural Experiment Station

Abstract

Methyl thiouracil is a potent goitrogen when fed to swine. The inclusion of 0.25 percent methyl thiouracil in the feed was less effective than either 0.05 or 0.10 percent. Methyl thiouracil at 0.05 and 0.10 percent levels was more effective than thiouracil at a 0.25 percent level.

Daily gains made by hogs receiving methyl thiouracil, as compared with gains made by control hogs, appeared to be related to initial body weight. Above 146 pounds the experimental hogs gained more rapidly but below 137 pounds they gained less rapidly than the control hogs.

In three trials, hogs fed a ration containing 0.10 percent methyl thiouracil required 36, 29, and 18 percent less feed per unit of gain than did the control hogs. In two trials hogs fed a ration containing 0.05 percent methyl thiouracil required 28 and 23 percent less feed than did the control hogs.
