Isiphi isilwane inja yakho - i-carnivore noma i-omnivore?

Izinja ziyingxenye yomndeni we-canine, i-oda lama-carnivores, kodwa lokhu akusho njalo ukuziphatha okuqondile, i-anatomy, noma izintandokazi zokudla.

Zahlulele wena

Ezinye izilwane zingase zibukeke njengezilwane ezidla ezinye futhi ziziphathe njengezilwane ezizingelayo. Kodwa ingabe bayizilwane ezidla ezinye ngempela? Wena yiba yijaji.

• Izimpisi zihlasela izilwane ezidla uhlaza, kodwa okokuqala zidla okungaphakathi kwezisu zazo, kanye nengaphakathi lalezi zilwane.¹
• Ama-coyote adla ukudla okunhlobonhlobo, okuhlanganisa izilwane ezincelisayo ezincane, izilwane ezihlala emanzini, izinyoni, izithelo kanye nendle yezilwane ezidla uhlaza.
• AmaPanda nawo ayizilwane ezidla inyama, kodwa ayizilwane ezidla utshani futhi adla amaqabunga oqalo.

Ukuthola iqiniso

Izilwane ezidla inyama eziqinile noma zangempela ezifana namakati zinesidingo esiphezulu se-taurine (i-amino acid), i-arachidonic acid (i-fatty acid) namanye amavithamini (i-niacin, i-pyridoxine, i-vitamin A) atholakala kumaprotheni ezilwane kanye nemithombo yamafutha.

Ama-Omnivores, njengezinja nabantu, awanayo imfuneko ephezulu ye-taurine namavithamini athile futhi angakhiqiza i-arachidonic acid emafutheni emifino ngokwawo.

Izimpawu zama-omnivores

Kunezinye izici zokudla okunomsoco, zokuziphatha nezomzimba ezihlukanisa le mihlaba emibili - ama-omnivores kanye nezilwane ezidla inyama:

• Izinja zinamazinyo (ama-molars) anezindawo eziyisicaba, eziklanyelwe ukugaya amathambo kanye nezinto zezitshalo ezine-fibrous.
• Izinja zingakwazi ukugaya cishe u-100% wama-carbohydrate eziwadlayo.²
• Ezinjeni, ithumbu elincane lithatha cishe amaphesenti angu-23 omthamo ophelele wepheshana lesisu, ngokuhambisana namanye ama-omnivores; emakati, ithumbu elincane lithatha amaphesenti angu-15 kuphela.^3,4
• Izinja zingenza uvithamini A nge-beta-carotene etholakala ezitshalweni.

Ukudideka eziphethweni

Abanye abantu benza iphutha lokuphetha ngokuthi izinja, nakuba ziyizilwane ezifuywayo, kumelwe zimane nje zibe izilwane ezidla inyama ngoba ziyingxenye yezilwane ezidla inyama. Ukuhlolisisa i-anatomy, ukuziphatha, kanye nokudla okuthandwayo kwezinja kuholela esiphethweni sokuthi empeleni ziyi-omnivores: ziyakwazi ukuhlala ziphilile ngokudla kokubili ukudla kwezilwane nezitshalo.
