Phase Changes of Enzyme Activity in Hind Gut Tissues of Piglets

Abstract

This article describes nature and intensity of agerelated changes in the activity of transferases, phosphatases and a-amylase in the tissues of middle and bung guts of the large intestine of piglets in colostrum, colostrum-dairy, first, second and third dairy, dairy-plant, first and second plant phases of nutrition in the early postnatal period of systemogenesis. Activity of enzymes is determined by the spectrophotometric method in the scientific laboratory of the Chuvash State Agricultural Academy. It was revealed that high metabolic processes in the tissues of middle and bung guts of piglets are found in the colostrum, colostrum-dairy, and the first and second phases of the definitive nutrition. The lowest activity of metabolic processes is detected in the phases of the first, second and third dairy nutrition, and the second transition phase is in between. In the tissues of external and internal middle guts, the ALT activity is stabilized from the first definitive phase. Activity of AST, GGT and a-amylase in the tissues of external and internal middle guts is not stabilized during the studied early postnatal systemogenesis. Activity of ALP and AP in tissues of these guts is stabilized from the first definitive phase. ALT, AST, GGT and aamylase do not stabilize in the bung gut tissues during the studied early postnatal systemogenesis. ALP and AP activity in tissues of this gut is stabilized from the dairy-definitive phase.
