Trophallaxis: eating food regurgitated by another animal; Zoopharmacognosy: self-medication by eating plants, soils, and insects to treat and prevent disease. An opportunistic feeder sustains itself from a number of different food sources, because the species is behaviourally sufficiently flexible.
A gummivore is an omnivorous animal whose diet consists primarily of the gums and saps of trees (about 90%) and insects for protein. [1] Notable gummivores include arboreal, terrestrial primates like certain marmosets and lemurs. These animals that live off of the injuries of trees live from about 8m off of the ground up to the canopies.
Cecotropes (also caecotropes, cecotrophs, cecal pellets, soft feces, or night feces) are a nutrient filled package created in the gastrointestinal (GI) tract, expelled and eaten by rabbits and guinea pigs (among other animals) to get more nutrition out of their food. The first time through the GI tract, small particles of fiber are moved into ...
Digestive system of ruminants [ edit ] Hofmann and Stewart divided ruminants into three major categories based on their feed type and feeding habits: concentrate selectors, intermediate types, and grass/roughage eaters, with the assumption that feeding habits in ruminants cause morphological differences in their digestive systems, including ...
Artiodactyls survived in niche roles, usually occupying marginal habitats, and it is presumably at that time that they developed their complex digestive systems, which allowed them to survive on lower-grade food. While most artiodactyls were taking over the niches left behind by several extinct perissodactyls, one lineage of artiodactyls began ...
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.
A monogastric digestive system works as soon as the food enters the mouth. Saliva moistens the food and begins the digestive process. (Note that horses have no (or negligible amounts of) amylase in their saliva). After being swallowed, the food passes from the esophagus into the stomach, where stomach acid and enzymes help to
Radiodonta digestive system. The arthropod digestive system is divisible into three areas: the fore gut, mid gut, and hind gut. All free-living species exhibit a distinct and separate mouth and anus, and in all species, food must be moved through the digestive tract by muscular activity rather than cilia activity since the lumen of the fore gut ...
