Pancreatic Hypertrophy and Chick Growth Inhibition by Soybean Fractions Devoid of Trypsin Inhibitor.

Abstract

Fractionation studies on raw soybean meal have shown that the major chick growth inhibiting factor resides in the water insoluble residue. This fraction was devoid of anti-trypsin activity. Other fractions which contained high anti-trypsin activity were found to have an innocuous effect on growth of chicks. In all cases, where growth depression occurred, the pancreas was markedly hypertrophied.
