摘要：This paper describes the patterns of changes in the activity of transferases, phosphatases and α-amylase in the tissues of the jejunum in piglets in the colostrum, colostric-dairy, first, second and third dairy, dairy-vegetable, first and second plant phases of nutrition in the early postnatal period systemogenesis. Age-related changes in the activity of aspartate aminotransferase, alanine aminotransferase, γ-glutamyltransferase, α-amylase, alkaline and acid phosphatase in the tissues of the proximal, medial and distal parts of the jejunum in purebred piglets of large white breed grown in the conditions of the pig complex of OJSC "Vurnarsky meat-processing plant" in the Vurnarsky district of the Chuvash Republic were determined. The activity of enzymes is determined by the spectrophotometric method in the scientific laboratory of the FSBEI HE Chuvash State Agricultural Academy. The most pronounced changes in the activity of enzymes in the tissues of the jejunum, associated with changes in the main external food factor - the composition and quantity of feed components, are detected during the first four months of life of the piglets.
