Tus nees yog qhov tshwj xeeb hauv qhov feem ntau ntawm kev zom ntawm lawv cov khoom noj tshwm sim hauv hindgut los ntawm cov txheej txheem fermentation nrog kev pab los ntawm ntau lab tus kab mob tshwm sim thiab protozoa (ua ke hu ua microbes). Lub cecum thiab cov hnyuv loj loj Cov hnyuv loj, tseem hu ua lub plab hnyuv loj, yogqhov kawg ntawm txoj hnyuv thiab ntawm lub plab zom mov hauv vertebrates. Cov dej tau nqus ntawm no thiab cov khoom pov tseg uas tseem tshuav yog khaws cia ua cov quav ua ntej yuav muab tshem tawm los ntawm qhov quav. https://en.wikipedia.org › wiki › Loj_intestine

hindgut fermentation tshwm sim nyob qhov twg?
Hindgut fermentation yog txheej txheem digestive pom nyob rau hauv monogastric herbivores, tsiaj nrog ib tug yooj yim, ib-chambered plab. Cellulose yog zom nrog kev pab ntawm cov kab mob symbiotic. Cov kab mob microbial fermentation tshwm sim hauv cov plab hnyuv siab raum ua raws cov hnyuv me: cov hnyuv loj thiab cecum.
Roughages fermented nyob rau hauv nees digestive ib leeg nyob qhov twg?
Modified monogastrics mus rau tib txoj kev: zaub mov pib ntawm lub qhov ncauj, ces mus rau hauv txoj hlab pas, plab, hnyuv me, thiab txoj hnyuv loj mus rau cecum. Lub cecum yog qhov chaw fermentation tshwm sim. Ntawm no cov as-ham raug muab los ntawm cov zaub mov thiab tom qab ntawd nws nkag mus rau hauv qhov quav thiab tawm ntawm lub cev.
Qhov twgPuas yog fermentation ntawm fibrous feeds tshwm sim nyob rau hauv nees?
Cov cecum muaj 12-15% ntawm lub plab muaj peev xwm thiab txoj hnyuv 40-50% ntawm qhov muaj peev xwm. Lub luag haujlwm tseem ceeb ntawm lub hindgutyog cov microbial digestion (fermentation) ntawm cov khoom noj fiber ntau (cov qauv carbohydrates feem ntau los ntawm cov zaub mov hauv cov zaub mov noj).
Mechanical digestion tshwm sim nyob rau hauv nees nyob qhov twg?
Muaj 24 molars. Lawv txoj hauj lwm yog zom cov zaub mov. Qhov no yog thawj qhov chaw ntawm mechanical digestion. Cov qaub ncaug thiab lwm yam digestive enzymes tau ntxiv rau hauv qhov ncaujpib cov txheej txheem ntawm kev zom zaub mov.
