Abstract
Summary
An unheated, water insoluble fraction of soybean meal, while adding only .024% trypsin inhibitor to the diet, causes pancreatic hypertrophy in the chick. The hypertrophic pancreas has a higher trypsin specific activity than controls. Amylase specific activity was lower after feeding raw soybean meal but there was no difference after feeding the water insoluble fraction. These observations suggest that a heat-labile component other than trypsin inhibitor may be responsible for pancreatic hypertrophy and associated changes in enzyme levels in animals fed raw soybean meal.
