The avian pancreas has several features in contrast with the exocrine function of mammals. For example, the activity of pancreatic enzymes is much higher in birds than in mammals, with the secret rate of the avian pancreas exceeding the activity of mammal enzymes per one kilogram of live weight several times over. This difference can be explained by the adaptation of birds to flight. With the emergence of new data on the role of trypsin in the regulation of metabolism in animals, it becomes necessary to study the role of this signalling molecule in the regulation of pancreatic function, and metabolism in general. Obtaining information on all these research areas will form the basis for further research on the role of the pancreas in the body of birds.
A feature of birds is the heightened activity of pancreatic enzymes in pancreatic juice, which provide an intensive metabolism. It is also known that digestive enzymes are present in the blood of birds in an active state and affect various functions of the body. However, the role of digestive enzymes in avian blood is not well explored due to the lack of scientific data. Therefore, the purpose of this Research Topic is to determine the role of the pancreas in all life processes of birds. Discovering this will involve the following:
1) Studying age-related changes in the activity of pancreatic enzymes in birds
2) Investigating the adaptation of avian pancreatic enzymes to various feed ingredients and additives
3) Determining the change in pancreatic secretion in the pre- and postprandial phase of digestion
4) Studying the role of trypsin in the blood of birds
5) Studying the endocrine function of the avian pancreas
Knowledge of these issues is important for organizing rational nutrition for poultry and to further our understanding of the role of trypsin in the regulation of animal and human metabolism.
In this Research Topic, original research and Review articles, among other article types, are welcome on, but not limited to, the following topics:
1) Exocrine and endocrine function of the pancreas of birds
2) The effect of trypsin in the blood of birds on digestion and life processes
3) Influence of feed additives, type of diet and bird age on the activity of pancreatic enzymes in the blood of birds and digestion processes
