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

Detailed explanation-2: -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 pig has a digestive system which is classified as monogastric, or nonruminant. Humans also have this type of digestive system. They have one stomach (mono = one, gastric = stomach). The monogastric differs from that of a polygastric, or ruminant, digestive system found in cattle and sheep.

Detailed explanation-4: -The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds.

Detailed explanation-5: -Monogastric species – such as poultry, pigs and fish – are more reliant on grains and pulses that compete for land that could grow human food. Ruminant species – such as sheep, cattle and goats – rely more on grasses and forages that are inedible by humans.
