Identification of Histological Structure Small Intestine of Bali Pig in the Starter and Grower Phase

Changes in morphometry and intestinal function can be caused by several factors such as age and feed. Population of bacterial  in the digestive tract causes a modification of the microstructure and immune system in the digestive tract. The health of the digestive system is very influential on the level of livestock productivity. This study aims to identify changes in the histological structure of the small intestine of pigs in the starter and grower phases. This research is a descriptive study. The samples used were duodenum, jejenum and ileum from six bali pigs each with three in the starter phase and three in the grower phase. Samples taken were fixed in 10% Formalin Neutral Buffer solution, then processed for the preparation of histological preparations with Hematoxylin Eosin (HE) staining technique. Data were collected from observations of histological structures of tunica mucosal, submucosal, muscular and serous of  duodenum, jejenum and ileum of the pigs using binocular light microscopes with 40, 100 and 400 magnifications . The analysis of the histological structure is presented in a descriptive qualitative.
