Pseudoruminant

 ( Mammal Taxonomy ) 

Pseudoruminant is a classification of animals based on their digestive tract differing from the . Hippopotamidae and camels are ungulate mammals with a three-chambered stomach (ruminants have a four-chambered stomach) while Equidae (horses, Asinus, zebras) and rhinoceroses are monogastric herbivores.Fowler, M.E. (2010). "Medicine and Surgery of Camelids", Ames, Iowa: Wiley-Blackwell. Chapter 1 General Biology and Evolution addresses the fact that camelids (including llamas and camels) are not ruminants, pseudo-ruminants, or modified ruminants.

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.
