What are they?
• Animals with specialized digestive tracts are still non-ruminant animals but they have unique organs that allow them to efficiently process the food they consume

Hindgut Fermenters
• Non-ruminant herbivores that have a functioning cecum that allows them to eat large amounts of roughage – Horses– Rhinos– Elephants– Rabbits– Guinea Pigs

Bird Systems
• Beak– Mouth which pecks and scoops feed
• Salivary Glands– Add digestive enzymes and lubricate feed
• Esophagus– Connects beak to the crop
• Crop– Storage pouch that moistens feed

Bird Systems
• Proventriculus– Glandular stomach that adds gastric juices
and mixes and churns feed
• Gizzard– Purplish colored organ that contains grit to
grind feed during muscle contractions
• Small Intestine– Digests and absorbs nutrients

Bird Systems
• Large Intestine– Absorbs water
• Ceca– 2 blind pouches that do not function at the
end of the large intestine
• Cloaca– Internal sphincter that controls excretion
• Vent– External sphincter that controls excretion
