—ruminantly, adv./rooh"meuh neuhnt/, n.1. any even-toed, hoofed mammal of the suborder Ruminantia, being comprised of cloven-hoofed, cud-chewing quadrupeds, and including, besides domestic cattle, bison, buffalo, deer, antelopes, giraffes, camels, and chevrotains.adj.2. ruminating; chewing the cud.3. contemplative; meditative: a ruminant scholar.[1655-65; < L ruminant- (s. of ruminans, prp. of ruminari, ruminare to chew cud, meditate), equiv. to rumin- (s. of rumen) RUMEN + -ant- -ANT]
* * *Any cud-chewing ungulate, including antelope, camels, cattle, deer, giraffes, goats, okapis, pronghorn, and sheep.Most ruminants have a four-chambered stomach, two-toed feet, and small or absent upper incisors. Camels and chevrotains have three-chambered stomachs. Ruminants eat quickly, storing masses of grass (grazers) or foliage (browsers) in the first stomach chamber, the rumen, where it softens. They later regurgitate the material, called cud, and chew it again to break down the undigestible cellulose. The chewed cud goes directly to the other chambers, where various microorganisms help in its digestion.
* * *▪ suborder of mammalsany mammal of the suborder Ruminantia (order Artiodactyla), which includes the pronghorns, giraffes, okapis, deer, chevrotains, cattle, antelopes, sheep, and goats. Most ruminants have four-chambered stomachs and a two-toed foot. The upper incisors are reduced or sometimes absent. Camels and chevrotains, however, have a three-chambered stomach. Ruminants eat quickly, storing masses of grass or foliage in the first chamber of the stomach, the rumen, where it softens. They later regurgitate this material, called cud, and chew it again to further break down its cellulose content, which is difficult to digest. The chewed cud goes directly to the other chambers of the stomach (the reticulum, omasum, and abomasum), where it is further digested with the aid of various essential microorganisms that live in the stomach.
