Abstract

We have determined the patterns for age-specific changes related to activity of aspartateaminotransferase, alanineaminotransferase, gamma glutamyltransferase, ?-amylase, alkaline phosphatase and acid phosphatase in different parts of the stomach, liver, pancreas, duodenal, empty, ileac, cecum, colic and straight intestine of large white pigs at the age of 1, 7, 14, 21, 28, 60, 120 and 180 days that have been grown up in a pig-breeding farm. We have defined the principles and strength of age-specific changes related to activity of the studied ferments at the colostric, colostric-dairy (at the first transitional), first dairy, second dairy, third dairy, dairy-definitive (at the second transitional), first definitive and second definitive feeding stages in the early postnatal period of the pig systemogenesis. We have found out that in each separate feeding stage the activity of the studied ferment in various parts of the digestive organ is different. The speed of the metabolic process in the digestive system tissues, the intensity of their maturation, and functioning of each part of the digestive organ at each feeding stage are quite different. The degree of structural and chemical changes in pigs is high at early stages of the postnatal period within the first four months of pig life. They are particularly distinctive at the transitional feeding stages. The terms of particular ferment activity stabilization in digestive organs have been determined. They can be indicated at the late stages of pig feeding.
