title: Intestinal brush border and lysosomal enzymes and immunoglobulin absorption in the newly-born lamb.
abstract: Activities of the brush border enzymes alkaline phosphates, leucine aminopeptidase and lactase and the lysosomal enzymes alpha-mannosidase and beta-N-acetylglucosaminidase increased in the serum of newly-born lambs fed colostrum. Feeding lipid and protein components of colostrum and bovine serum resulted in enzyme responses similar to those observed after feeding colostrum. Activities of each of the enzymes increased in mesenteric lymph collected from newly-born lambs when immunoglobulins were being absorbed from the jejunum and ileum.
