Ruminantia

Ruminantia sunt mammalia ordinis Artiodactylorum quae cibum conficiunt, primum in stomacho emolliendo, tum massam partim confectam, nunc cud (Anglice) appellatam, vomendo et remandendo, inter quae boves, caprae, oves, cervi, dorcades. Omnia ruminantia ruminant, sed non omnia ruminantia ad subordinem Cetruminantium pertinent: cameli et lamae sunt exceptiones, subordo Tylopodorum coniunctim appellatae.^[2] Etiam sunt magna mammalia pascentia quae, quamquam sensu stricto non ruminantia, similes habent adaptationes ad cibum mediocrem utendum; exempla sunt Macropodidae et equi.
