ANATOMY

Detailed explanation-1: -Two blind pouches called the ceca (singular: cecum) are attached at the junction between the small intestine and large intestine. Microorganisms capable of breaking down fibrous material live in the ceca. However, this is not a significant part of the digestion system in modern birds.

Detailed explanation-2: -Chickens have two ceca, blind pouches of about 7 inches ( 17cm) that branch at the beginning of the large intestine. When food comes in via the small intestine, it’s first stored in the ceca to reabsorb water. In the ceca, a fermentation process breaks down crude fibers.

Detailed explanation-3: -Ceca. The ceca (plural form of cecum) are two blind pouches located where the small and large intestines join. Some of the water remaining in the digested material is reabsorbed here. Another important function of the ceca is the fermentation of any remaining coarse materials.

Detailed explanation-4: -The caeca in galliformes are usually long and particularly well developed with a constricted proximal portion, measured by Clarke ( 1978) to be one to two millimetres wide in three-week-old chickens, and join the colon just distal to the muscular ring separating the ileum from the colon.

Detailed explanation-5: -The best developed of the intestinal type, gallinaceous ceca range from long to very long (6-34 cm), with extreme lengths of 35-92 cm in certain grouse in winter (Moss 1983). The ceca usually widen apically or end in a bluntly rounded tip rather than tapering at the apex and may contain internal submucosal folds.
