The aim of this study was to determine the influence of raw and extruded feed containing soyabean meal on pancreatic juice enzyme activities in young calves. Experiments were carried out on twelve calves cannulated 3 weeks after birth. The calves from the control group were fed a semiliquid diet (milk and cereal mixture). The calves from the experimental groups received a semiliquid diet containing additionally soyabean meal in either raw or extruded form. A significant increase of protein and trypsin output as well as proteolytic activity in the pancreatic juice was observed in calves fed the diet with raw soyabean meal.
