Mammal whose stomach has four compartments; the rumen, the reticulum, the omasum, and the abomasum.
rumen
large fermentation vat, which contatns bacteria, and protozoa that break down plant materials.
reticulum
has a honeycomb like lining called tripe. it interacts with the rumen, in initiating the mixing activity of the rumen and providing additional area for the fermentation process.
omasum
has a large absorptive area because of its many folds. removes the water from the mixture received from the reticulum
abomasum
this is the true stomach where most digestion is completed
products of ruminant fermentation
methane and carbon dioxide
the reason why ruminants can regurgitate and chew their cud
because their is no esophageal sphincter
why it is possible to feed ruminants
because the microbes present in the rumen synthesize all the protein needed and the animal can digest the microbes after they have died also
how many volative fatty acids does the rumen produce
3
the types of fatty acids that the rumen produces
acetate
propionate
butyrate

these are the main sources of energy for the ruminant
examples of hindgut fermentors
horse
rabbit
the reason why ruminants can regurgitate and chew their cud
because their is no esophageal sphincter
