Pseudoruminant
Pseudoruminant is a classification of animals based on their digestive tract differing from the ruminants. Hippopotami are ungulate mammals with a three-chambered stomach (ruminants have a four-chambered stomach) while equids (horses, asses, zebras) and rhinoceroses are monogastric herbivores.[1][2]
Anatomy
Like ruminants, some pseudoruminants may use foregut fermentation to break down cellulose in fibrous plant species (while most others are hindgut fermenters with a large cecum). But they have three-chambered stomachs (while others are monogastric) as opposed to ruminant stomachs which have four compartments.
