초록
The present study was focussed mainly on the morphological changes of the glandular tubules in the large intestine according to age of piglets. Samples were taken from large intesine of 1-, 10-, 20-, 35- and 45-day-old piglets, 2 to 3 piglets in each age group. The intestinal samples were fixed in 10% neutral formalin solution, dehydrated, and then paraffin sections were stained with H-E. The results observed were summarized as follows: 1. The mucosal glands in the cecum and colon tend to be unbranched simple straight tubular glands, or often two or more branched simple stright tubular glands. 2. The number of the longitudinal folds and the number of the crypts per cross section of piglet colons, respectively, were 1-day-old piglets-
