what are the 4 stomachs of rumnant digestion
rumen, abomasum, omasum and reticulum
what is the rumen made of
keratatinised stratisfies squamous epithilium
what occours in the rumen
material is drawn back into the mouth, liquid rapidly re-swallowed and corse material cheewed again
whats the rumen coverd in
ruminal papillae
whats the rumen connected to, what do they provide
reticulum, a culture system for anarobic and symbyotic microoganisms
whats the role of the microorganisms
break down diffrent food sources, fermentation produces volitile fatty acids that can be used for energy
describe the abomasum stomach
contains gastric pits, glandular and made of simple columnar epithilium
whats the role of the omasum
regulates food entry into the abomasum, food may return to the reticulo rumen. mainly for water absorbtion
what epithilia is the reticulum made from
keratonised stratisfied squamous
whats the ring of muscle in the reticulum called and whats its job
muscularis mucosa, aids in seperation mixing and breakdown
whats the reason they need this manuy stomachs
cellulose and hemicellulose - binds to lignin and reduces digestability
where is the majority of cellulose digestion done
reticulo rumen
whats the first stage of cellulose digestion
organisms have to get the cellulose
whats the second stage of cellulose digestion
they stick themself to the cellulose - can be nonspecific or specific
how is the second stage of digestion done
the cellusome in the bacteria wall has CBD that allows it to bind to cellulose attached on the same thing are hydrolises that hydrolise cellulose
whats stach made of
amylose and amylopectin
how is stach digestes
mostly digested in the rumen and used by microorganisms that produce - heat, gas propiate acitate and butyrate
describe protien digestion
most of the protien that reches the abomasum will be of microbial orogin. can add urea to the diet from which they can make amino acids
