Ufuna ukwazi izibonelo zezilwane ezidla utshani? Thola izinga lakho? Kule ndatshana yePeritoAnimal sichaza ukuthi ini izilwane ezidla kakhulu ezinezibonelo kanye nezifiso kaningi, izici zayo neminye imininingwane ngokuziphatha kwayo.

Khumbula ukuthi izilwane ezidla utshani noma izilwane ezinemilomo emikhulu yilezo ezidla kakhulu izitshalo, hhayi utshani nje kuphela, futhi zizithatha "njengabathengi bokuqala".

Sichazwa kanjani isilwane esidla imifino?

Isilwane esidla utshani kungaba ngesakhe Ukudla kuyinto yemifino kuphela, ngokuba izitshalo namakhambi izithako zawo. Ingxenye eyisisekelo yemifino yi-cellulose, i-carbohydrate eyinkimbinkimbi kakhulu noma i-carbohydrate. Le carbohydrate noma i-carbohydrate kunzima kakhulu ukuyigaya, kepha imvelo, ngaphezulu kwezigidi zeminyaka yokuziphendukela kwemvelo, isungule amasu amaningi okusetshenziswa kwayo.

Kugaywa kanjani i-cellulose?

Izilwane ezidla ubhedu zingasebenzisa i-cellulose ngenxa yezenzo ezimbili noma ukugaya: ukugaya ngomshini, ngenxa yamazinyo akhethekile, anomumo oyisicaba, oqukethe ukuhlafuna izitshalo; nenye ngenxa isenzo sezilwanyana ezincane ezinendlela yakho yokugaya ukudla. Lezi zinambuzane ezincane, ngokusebenzisa ukuvutshelwa, ziyakwazi ukuguqula i-cellulose ibe yimikhiqizo elula, eyinhloko i-glucose.

Yiziphi izinhlobo zezilwane ezidla utshani ezikhona?

Kunamaqembu amabili amakhulu: polygastric futhi monogastric. Njengoba igama lalo lisho, okwangaphambili yikhona okunezisu eziningana (empeleni kuyisisu nje esinamakamelo amaningana axhumanayo). Kwamanye amagumbi kukhona ukuhlushwa okukhulu kwama-microorganism akwazi ukubola i-cellulose. Amazinyo abuye akhetheke kakhulu, ngoba ayizicaba futhi umhlathi ongenhla awunazinsimbi. Isibonelo salezi zilwane yilezo ezinezinselo ezimbili, ezaziwa nangokuthi ama-ruminants. Futhi banokubonakala okuhlukile kokukwazi ukuphinda bavuselele ingxenye yokuqukethwe esiswini ukuze bakwazi ukubuyela ekuhlafunweni noma ekukhanyeni. Isibonelo salezi zilwane kukhona izinkomo, izimbuzi nezimvu.

Ama-monogastrics yiwo anesisu esisodwa kuphela, ngakho-ke ukuvutshelwa kwenzeka kwenye indawo ohlelweni lokugaya ukudla. Lokhu kunjalo ngehhashi nonogwaja. Kulokhu, kunentuthuko enkulu yabangaboni. Ilele phakathi kokuphela kwamathumbu amancane nokuqala kwamathumbu amakhulu, ifinyelela ukukhula okukhulu. Ezilwaneni ezidla utshani eziba yodwa azikho amathuba okuqhuma futhi, uma kwenzeka amahhashi, Unenselo eyodwa kuphela futhi inezinsimbi emhlathini ongenhla.

Uma kwenzeka kuba onogwaja (lagomorphs), imikhiqizo ebangelwa ukuvutshelwa kwe-cecum iyaxoshwa ngendle. Le ndle "ekhethekile" yaziwa ngokuthi ama-cecotrophs futhi ifakwa onogwaja ukuze kusizakale zonke izakhamzimba eziqukethe. Lezi, nazo, zinokusebenza kwamazinyo okukhetheke kakhulu, lapho kukhona khona amazinyo akhula ngokuqhubekayo (izintambo ezingaphezulu nezingezansi).

Yiziphi izilwane ezidla utshani ezibaluleke kakhulu?

Eziningi zalezi zilwane zithanda ukuhlala ngamaqembu noma imihlambi (zihlangene) futhi zithathwa njengezisulu. yingakho ukuma kwamehlo abo kusezinhlangothini (ukuze bakwazi ukubona ukuthi ngubani obaxoshayo ngaphandle kokujika ikhanda) futhi, ngaphezu kwalokho, bathambekele ekugwemeni ukweqisa isimilo.

Okubaluleke kakhulu yilezi izinkomo (izinkomo), i- izimvu (izimvu) kanye izimbuzi (izimbuzi). Endabeni yama-monogastrics esinawo amahhashi, wena amagundane kanye ne- lagomorphs (onogwaja).
