[Effect of different food stimuli on pancreatic exocrine function in ontogeny].
The fermentative adaptation of the pancreas to the quality of food through determination of the amylase, lipase and proteases activity in the contents of the small intestine and the gland homogenate on an empty stomach and 2 hours feeding on the egg white, bread and walnuts were studied in chickens aged 1-60 days. The 1-2 day old chicken are shown to lack the ability to adapt the gamut of pancreatic enzymes to the quality of the stimulant. This ability appears on the 5th day and becomes persistent by the 20th day of life. The adaptability of pancreatic enzymes manifests itself in a predominant rise of the lipolytic activity of the chyme after feeding on a fat stimulant and in the activity of proteases after feeding on protein. In paultry of the age under consideration the fermentative adaptability to carbohydrate food is lacking.
