The primary difference between ruminants and nonruminants is that ruminants' stomachs have four compartments: rumen—primary site of microbial fermentation; reticulum; omasum—receives chewed cud, and absorbs volatile fatty acids; abomasum—true stomach; The first two chambers are the rumen and the reticulum.
Two-headed farm animals sometimes travel with animal side shows to county fairs. Most notably, The Venice Beach Freakshow supposedly houses the largest collection of two-headed specimens in the world, including over 20 two-headed animals that are alive. Many museums of natural history contain preserved two-headed animals.
The rumen, also known as a paunch, is the largest stomach compartment in ruminants. [1] The rumen and the reticulum make up the reticulorumen in ruminant animals. [2]The diverse microbial communities in the rumen allows it to serve as the primary site for microbial fermentation of ingested feed, which is often fiber-rich roughage typically indigestible by mammalian digestive systems.
Echinoderms possess a simple digestive system which varies according to the animal's diet. Starfish are mostly carnivorous and have a mouth, oesophagus, two-part stomach, intestine and rectum, with the anus located in the centre of the aboral body surface. With a few exceptions, the members of the order Paxillosida do not possess an anus.
Tylopoda (camels, llamas, and alpacas) and chevrotains have three-chambered stomachs, while the rest of Ruminantia have four-chambered stomachs. The handicap of a heavy digestive system has increased selective pressure towards limbs that allow the animal to quickly escape predators. [35]
All bovids have four toes on each foot – they walk on the central two (the hooves), while the outer two (the dewclaws) are much smaller and rarely touch the ground. [ 3 ] The bovids show great variation in size: the gaur can weigh more than 1,500 kg (3,300 lb), and stand 2.2 m (87 in) high at the shoulder. [ 27 ]
Two options are to provide free choice salt/mineral powder or feed a specially formulated ration. Indigenous to the highest regions of the Andes, this harsh environment has created an extremely hardy animal, so only minimal housing and predator fencing are needed. [49] The alpacas' three-chambered stomachs allow for extremely efficient digestion.
Because of this, camelids have to lie down by resting on their knees with their legs tucked underneath their bodies. [1] They have three-chambered stomachs, rather than four-chambered ones; their upper lips are split in two, with each part separately mobile; and, uniquely among mammals, their red blood cells are elliptical.
