The Comparative Effect of Prolonged Feeding with Raw and Heated Soybean Meal on the Growth Response, Pancreatic Enlargement and Pancreatic Enzymes of Chicks

Abstract
Prolonged feeding of chicks with raw soybean meal as the main protein source in the diet resulted in growth inhibition, pancreas enlargement, and increased content of pancreatic proteolytic enzymes. The effect of feeding with raw soybean meal as compared to heated soybean meal upon total intestinal enzymatic activities in chicks was tested. The tendency of chicks to overcome the effects of raw soybean meal is expressed mainly by the increase of biosynthesis and secretion of proteolytic enzymes in the pancreas.
