Pseudoruminant

Pseudoruminant is a classification of animals based on their digestive tract differing from the ruminants. Hippopotami and camels are ungulate mammals with a three-chambered stomach (ruminants have a four-chambered stomach) while equids (horses, asses, 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.{{Cite book|title=The Encyclopedia of Mammals|last=Laws|first=Richard|publisher=MacDonald D. ed|year=1984|isbn=0-87196-871-1|location=New York|pages=[https://archive.org/details/encyclopediaofma00mals_0/page/506 506–511]|url-access=registration|url=https://archive.org/details/encyclopediaofma00mals_0/page/506}}
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.
