Characteristics of the Exocrine Pancreatic Secretion of the Young Pig1, 2, 3

Abstract

The secretion rate and composition of pancreatic juice of pigs between 3 and 7 weeks of age, prepared with chronic pancreatic fistulas, fluctuated markedly and often unpredictably. The variables measured include volume and amylase, protease and lipase activity. The components of the secretion varied independently of one another, indicating that variations were not due simply to concentration changes. In a comparison of dietary effects one pig fed a soybean-protein diet secreted about five times as much amylase, protease and lipase, and twice the volume of pancreatic juice secreted by a similar pig fed a milk-protein diet. The results indicate that the pancreas plays a prominent digestive role in the young pig. Protein and dry matter digestibility was lower for pigs with chronic pancreatic fistulas than for sham-operated control pigs less than 45 days of age, confirming a digestive function of the pancreas at this early age.
