ABSTRACT: The data of an experimental study of the influence
of feeding and the conditional stimulus on digestive function in birds is
presented. It is
stated that feed consumption is a powerful stimulator of pancreatic secretion
in broiler chicks. The secretory response of the pancreas was the highest in
the morning when secretion of pancreatic juice was 1.8 times higher, amylase
activity 3.2 times, proteases activity 3.3 times, lipase activity 2.1 times
higher than before feeding (basal levels). The regulation of pancreatic
activity is known to be complex-reflex with conditioned-reflex component being
very important since it provides 25% higher juice secretion and 42% - 74% higher enzyme secretion compared to the basal
levels during few minutes after the conditional signal.
