Histo-Physiological Studies on Chick Pancreas as Influenced by Feeding Raw Soybean Meal.

Abstract
Pancreatic hypertrophy in chicks fed raw soybean meal is caused by an accumulation of the zymogen material in the acinar cells. Failure of the pancreas to respond in the expected way to pilocarpine injection suggested that the raw soybean meal interferes in some way with the basic mechanism by which zymogen is released from the pancreatic cells.
