Abstract: The research focuses in studying the micro and maw morphology, and also mums substantial on the digestive tract of the swift. The observation was held to the macromorpho'logy alffer the fixation in Bwin solution and followed with microanatomy on the mucus composition on the digestive tract using Haematoxylin-Eosin and Afcian Blue-Periodic Acid Schifft (A5'PAS) staining method. The aim of this study is to make a better understanding about the relation between feeding behavior and morphology of digestive tract. The avwage sites of C. hdphaga are 2800 gram body weight and 9.2 cm body length. The swift's digestive tract consists of mouth, pharynx, oesophagus, stomach, small intestine, large intestine and cloacae, Caecum was failed and thereffore the border between small intestine and large intestine is difficult to be recognized. The average length of intestine is 11.7 cm The average length of oesophagus is 4.00 cm or 45% length of the body. The cmp as temporary food storage was not found, but there are many active mesophagus glands found on the transition between oesophagus and stomach. The stomach conskts of proventriculus and ventrkuius. The surface of pmventriwlus is lined by a thick keratin shield. The mums of pmventrkulus is Ined by simple columnar epithelium and the proventriculus gland formed labulus called adenomere. The ventriculus is divided into cardia, fundus, and pylorus zones. Ventriculus is arranged by the simple columnar epithelium. The surface of ventriculus is lined with a thick keratin shield. Vili of smatl intestine are long and crowded, getting shorter toward to the caudal and disapear at the rectum. The Lleberkuhn gland was found and has no caecum. along the intesthe. C. fuciphaga needs fuel to go around their daily activities, and this is where the digestive system plays its role. it converts food into raw materials that build and fuel the body cells, so the digestive system must be effiicient.
