EVERYDAY SCIENCE

Detailed explanation-1: -Monogastric herbivores, such as rhinoceroses, horses, guinea pigs, and rabbits, are not ruminants, as they have a simple single-chambered stomach. These hindgut fermenters digest cellulose in an enlarged cecum.

Detailed explanation-2: -So, the correct answer is “Dog".

Detailed explanation-3: -Horses are non-ruminant, simple-stomached herbivores. They are hindgut fermenters, meaning the large intestine is the main site of fermentation of fibrous feedstuffs. This differs from ruminant animals like cattle, goats, deer, and sheep, which are foregut fermenters with a rumen and multicompartment stomach.

Detailed explanation-4: -Ruminant stomachs have four compartments: the rumen, the reticulum, the omasum and the abomasum. Rumen microbes ferment feed and produce volatile fatty acids, which is the cow’s main energy source.

Detailed explanation-5: -Some ruminant animals include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels while non-ruminant animals include human, horse, swine, fowl, dog, and rabbit.
