Description
Summary:The small intestinal maltase‐glucoamylase (MGAM) contributes to the starch digestion pathway in the small intestine. This study investigated ontogenic changes of MGAM in the hydrolysis of amylose along the longitudinal axis of the small intestine. Jejunal tissue was collected from pigs belonging to each of seven age groups (d 1, 4, 6, 12, 20, 28 and 70, n = 6) for MGAM enzyme kinetic experiments. The jejunum was divided into halves with the end closest to the stomach designated proximal (Px) jejunum and the other half designated the distal (Dt). Kinetic experiments of MGAM activity were conducted with six levels of purified amylose (0–100 μM) at 37°C and pH 6.0. On average postnatal growth increased (P
