Tseem muaj kev sib cav txog seb tus dev yog omnivorous los yog carnivorous Cov kev lag luam pub, kws kho tsiaj lossis kws paub txog zaub mov muaj kev xav sib txawv ntawm qhov no. Tsis tas li ntawd, qhov muaj pes tsawg leeg ntawm cov khoom noj sib txawv ntawm cov khoom noj sib txawv, txawm tias lawv yog cov khoom siv hauv tsev lossis kev lag luam, nyoos los yog siav, thiab txawm tias qhuav los yog ntub. dev noj dab tsi?

Nyob rau hauv tsab xov xwm no peb xav muab lo lus teb rau qhov kev tsis sib haum xeeb tam sim no uas piav qhia seb tus dev yog omnivorous los yog carnivorous, tag nrho raws li scientific and proven facts.

Diffferences of omnivorous animal and carnivorous animal

Los ntawm morphoanatomical thiab physiological taw tes ntawm view, qhov sib txawv ntawm cov hom tsiaj no yog nyob nruab nrab ntawm tag nrho cov ntawm lawv digestive ib ntsuj av thiab txhua yam hais txog nws.

Cov tsiaj txhu muaj cov hniav ntse uas pab rhuav cov nqaij sib cais, thiab lawv tsis zom ntau dhau, tsuas yog txaus rau zaub mov dhau. dhau ntawm txoj hlab pas. Txoj hauj lwm ntawm lub sij hawm noj mov feem ntau yog sawv ntsug nrog lub taub hau, qhov no nyiam cov khoom noj. Lwm qhov tshwj xeeb npaj rau kev yos hav zoov, yog claws

Peb yuav tsum tsis txhob thab nws nrog txoj hauj lwm tau los ntawm herbivorous tsiaj, xws li ungulates, txij li thaum lawv tsuas tau txais txoj hauj lwm no mus tshem tawm cov nroj tsuag, zom yog nqa tawm nrog lub taub hau.

Omnivorous tsiaj muaj paj molars, uas nyiam zom. Lub xub ntiag los yog tsis muaj tus kab mob tsim los tsis qhia tias tus tsiaj tsis yog omnivorous, vim nws poj koob yawm txwv yuav tsim tus nas los tiv thaiv nws tus kheej los yog nws yog carnivorous.

Qee yam ntxwv ntawm cov tsiaj txhu yog:

  • digestive tube ntawm cov tsiaj carnivorous luv luv, vim nws tsis tas yuav tag nrho cov txheej txheem ntawm digestive zaub, thiab lawv kuj tsis. muaj tib lub plab hnyuv zoo li omnivorous tsiaj.
  • The Digestive enzymes kuj txawv ntawm cov tsiaj no. Qee tus muaj cov enzymes tshwj xeeb hauv kev zom cov nqaij thiab lwm tus muaj qee cov enzymes ntawm herbivores thiab lwm tus ntawm carnivores.
  • LUB Ziab thiab ob lub raum tsis zoo tshaj li lwm cov tsiaj nrog lwm hom zaub mov.

Dab noj dab tsi?

Nyob hauv cov tsev feem ntau uas cov dev nyob, lawv feem ntau yog pub nrog pubuas muab zaub mov tiav thiab sib npaug. Muaj ntau yam khoom noj hauv khw rau ntau qhov sib txawv, hom, hnub nyoog lossis kab mob.

Yog peb ua tib zoo saib thiab saib cov ntawv qhia zaub mov peb yuav pom tias feem ntau ntawm lawv muaj high concentration of carbohydrates, ua rau peb xav tias nws yog ib qho tsim nyog rau tus dev noj khoom noj. Txawm li cas los xij, tsis yog li ntawd. Carbohydrates tsuas yog txo tus nqi ntawm cov khoom noj ua rau lawv nkag mus rau cov neeg siv khoom ntau dua, tab sis nws tsis yog cov khoom noj zoo rau peb tus dev, qhov tseeb, muaj ob peb yam khoom noj uas zoo rau kev noj zaub mov raws li cov khoom noj tiag tiag, xws li BARF noj rau dev.

Tsis tas li ntawd, tsis muaj qhov tsis ntseeg tias tus miv yog omnivorous los yog carnivorous, peb paub tias nws yog ib tug nruj carnivore, txawm li cas los xij, pub elaborated rau lawv kuj nqa carbohydrates. Kev noj zaub mov zoo rau tus dev yog ib qho raws li tsiaj protein, thiab tuaj yeem ntxiv lossis ntxiv cov zaub mov noj.

NOJ NTXHOS Vim li cas cov dev yog cov dev uas yog tus kws ua si carnivores

Dog yog facultative carnivores Qhov no txhais tau hais tias lawv muaj tag nrho cov yam ntxwv uas txhais cov carnivores, ob qho tib si anatomically thiab physiologically, tab sis rau tej yam vim li cas. Peb yuav piav qhia thaum kawg ntawm tsab xov xwm, lawv muaj peev xwm zom tau thiab assimilate cov as-ham xws li carbohydrates, muaj nyob rau hauv cov khoom noj xws li cereals, legumes los yog txiv hmab txiv ntoo.

LUB NOJ NIAM TUAG ZAUB DAB TSI DUA,)ZIB 1, 8 THIAB 4, 8 METERS

Qhov sib txawv ntawm cov tsiaj nyob rau hauv cov nqe lus ntawm qhov ntev, permeability thiab microbiota yuav tsum tau muab rau hauv tus account. Tib neeg, raws li ib tug omnivorous tsiaj, muaj ib txoj hnyuv ntawm 5 thiab 7 meters ntev. Yog tias koj muaj dev, koj tuaj yeem tshawb xyuas seb lawv cov hniav ntse npaum li cas, tshwj xeeb tshaj yog fangs, premolars thiab molars Nov yog lwm yam uas peb faib cov dev li. ib tug tsiaj carnivorous.

Raws li peb tau hais thaum pib, cov tsiaj txhu muaj qhov sib txawv plab hnyuvtshaj li tsiaj txhu los yog omnivorous. Cov kab mob hauv plab no ua haujlwm, ntawm ntau lwm yam, los pab ferment tej yam as-ham, xws li carbohydrates. Hauv cov dev, tus qauv carbohydrate fermentation tsis zoo, txawm hais tias tus tsiaj yuav tsum tau coj mus rau hauv tus account. Los ntawm qhov no, peb txhais tau hais tias muaj cov yug me nyuam uas assimilate cov as-ham zoo dua thiab lwm yam yug me nyuam NW nyuam qhuav assimilate lawv.

Lub hlwb feem ntau siv cov piam thaj los ua haujlwm. Cov dev tsis xav tau cov khoom noj carbohydrates, vim lawv muaj lwm txoj hauv kev metabolic uas lawv tsim cov piam thaj los ntawm cov protein. Yog li, yog tias tus dev tsis yog omnivore, yog vim li cas nws thiaj li muaj peev xwm assimilate ib co nroj tsuag as-ham?

Nutritional epigenetics

Teb cov lus nug yav dhau los nws yuav tsum nkag siab lub tswv yim ntawm epigenetics Epigenetics yog hais txog lub zog quab yuam los ntawm ib puag ncig ntawm caj ces. cov ntaub ntawv ntawm cov tsiaj muaj sia. Ib qho piv txwv meej tuaj yeem pom hauv kev yug me nyuam ntawm hiav txwv vaub kib, uas nws cov menyuam yug los yog poj niam lossis txiv neej nyob ntawm qhov kub thiab txias thaum lawv loj hlob.

Thaum lub sij hawm lub sij hawm domestication txheej txheem ntawm tus aub (tseem nyob rau hauv kev tshawb nrhiav), lub siab ntawm lawv ib puag ncig yuav ua rau muaj kev hloov nyob rau hauv lub synthesis ntawm enzymes lub luag hauj lwm rau lub digestive system ntawm as-ham, adapting dev kom ciaj sia los ntawm kev noj ib tug noj raws li "tib neeg pov tseg" Qhov no txhais tau tias, niaj hnub no, dev muaj peev xwm assimilate ntau cov as-ham los ntawm cov nroj tsuag.
