Detailed explanation-1: -Humans, swine, rabbits, chickens and horses all have a simple stomach, which is also known as a monogastric digestive system. Carnivores and omnivores have monogastric digestive systems.

Detailed explanation-2: -A monogastric is an animal with a single-compartmented stomach. Examples of monogastrics include humans, poultry, pigs, horses, rabbits, dogs and cats. Most monogastrics are generally unable to digest much cellulose food materials such as grasses.

Detailed explanation-3: -The main differences between ruminants and mo-nogastrics are monogastrics only have one compart-ment to their stomach, whereas ruminants have four compartments: rumen, reticulum, omasum, and abo-masum. Ruminants chew their food numerous times through a process called regurgitation or rumination.

Detailed explanation-4: -A monogastric digestive system has one simple stomach. The stomach secretes acid, result-ing in a low pH of 1.5 to 2.5. The low pH destroys most bacteria and begins to break down the feed materials. Animals with this type of digestive system are better adapted to eat rations high in concentrates.

Detailed explanation-5: -Monogastric: Single-chambered Stomach As the word monogastric suggests, this type of digestive system consists of one (“mono”) stomach chamber (“gastric”).
