Kulinganiselwa ukuthi inani lama-vegans e-UK lenyuke ngamaphesenti angama-360 kule minyaka eyishumi edlule, kanti cishe abantu abangama-542 baba yimifino. AmaNgisi ayisizwe sabathandi bezilwane, anezilwane ezifuywayo ezitholakala cishe ku-000% wamakhaya, anezinja ezingaba yizigidi ezingama-44 e-UK yonkana. Kungokwemvelo ukuthi ngamanani anjalo, ithonya le-veganism liqala ukusabalala ekudleni kwezilwane ezifuywayo. Ngenxa yalokho, kokubili ukudla kwenja yemifino kanye ne-vegan sekuvele kwakhiwe.
Amakati ayizilwane ezidla inyama engokwemvelo, okusho ukuthi adinga ukudla inyama ukuze aphile, kodwa izinja, ngokombono, zingaphila ngokudla okusekelwe ezitshalweni - nakuba lokho akusho ngempela ukuthi kufanele ubeke isilwane sakho kulokho kudla.
Izinja nezimpisi
Inja yasekhaya empeleni iyi-subspecies ye-grey wolf. Nakuba zihluka kakhulu ngezindlela eziningi, izimpisi nezinja zisakwazi ukuzalanisa futhi zikhiqize inzalo ephilayo nevundile.
Nakuba izimpisi ezimpunga zingabazingeli abaphumelelayo, ukudla kwazo kungashintsha kakhulu kuye ngendawo ezungezile kanye nenkathi yonyaka. Ucwaningo lwezimpisi e-Yellowstone Park e-US lubonise ukuthi ukudla kwazo kwasehlobo kuhlanganisa amagundane amancane, izinyoni, nezilwane ezingenamgogodla, kanye nezilwane ezinkulu ezifana ne-moose neminyuzi. Nokho, kuyaziwa ukuthi kanye nalokhu, izakhi zezitshalo, ikakhulukazi amakhambi, zivame kakhulu ekudleni kwazo - amasampula angu-74% we-wolf droppings aqukethe.
mayelana nezimpisi zabonisa ukuthi zidla kokubili okusanhlamvu nezithelo. Ubunzima bukhona eqinisweni lokuthi izifundo ngokuvamile azilinganisi ukuthi kungakanani ukudla kwezimpisi okuqukethe izinto zezitshalo. Ngakho, kunzima ukunquma ukuthi izimpisi omnivorous nezinja ezifuywayo zinjani.
Kodwa-ke, izinja azifani nezimpisi kukho konke. Inja kucatshangwa ukuthi yafuywa eminyakeni engu-14 edlule - nakuba ubufakazi bamuva bofuzo bubonisa ukuthi lokhu kwakungenzeka eminyakeni engu-000 edlule. Kuningi okushintshile ngalesi sikhathi, futhi ezizukulwaneni eziningi, impucuko yabantu nokudla kuye kwaba nethonya elikhulayo ezinjeni.
Ngo-2013, abacwaningi baseSweden banquma ukuthi i-genome yenja iqukethe inani elengeziwe lekhodi elikhiqiza i-enzyme ebizwa ngokuthi i-amylase, eyinhloko ekugayeni isitashi. Lokhu kusho ukuthi izinja zingcono ngokuphindwe kahlanu kunezimpisi ekugayeni isitashi—ezinhlangeni, kubhontshisi namazambane. Lokhu kungase kubonise ukuthi izinja ezifuywayo zingase ziphakelwe okusanhlamvu nokusanhlamvu. Abacwaningi baphinde bathola inguqulo yenye i-enzyme ebalulekile ekugayeni isitashi, i-maltose, ezinjeni zasekhaya. Uma kuqhathaniswa nezimpisi, le enzyme ezinjeni ifana kakhulu nohlobo olutholakala ezilwaneni ezidla uhlaza njengezinkomo nama-omnivores njengamagundane.
Ukujwayela izinja ekudleni okusekelwe ezitshalweni ngesikhathi sokufuywa akwenzekanga kuphela ezingeni lama-enzyme. Kuzo zonke izilwane, amabhaktheriya emathunjini ahilelekile ekugayweni kokudla ngezinga elilodwa noma elinye. Kutholakale ukuthi i-gut microbiome ezinjeni ihluke kakhulu kweyezimpisi - amagciwane akuwo maningi amathuba okuthi aphule ama-carbohydrate futhi ngokwezinga elithile akhiqize ama-amino acid avame ukutholakala enyameni.
Izinguquko zomzimba
Yona kanye indlela esiphakela ngayo izinja zethu ihluke kakhulu endleleni izimpisi ezidla ngayo. Izinguquko ekudleni, ubuningi kanye nekhwalithi yokudla ngesikhathi senqubo yokufuywa kwaholela ekwehleni kobukhulu bomzimba kanye nobukhulu bamazinyo ezinja.
baye babonisa ukuthi eNyakatho Melika izinja ezifuywayo zivame ukuphuphuma amazinyo futhi ziphuke kunezimpisi, nakuba ziphakelwa ukudla okuthambile.
Ubukhulu nokuma kogebhezi lwekhanda lwenja kunomthelela omkhulu ekhonweni layo lokuhlafuna ukudla. Umkhuba okhulayo wokuzalanisa izinja ezinezimbotshana ezimfishane uphakamisa ukuthi siqhubeka nokulumula izinja ezifuywayo ekudleni amathambo aqinile.
Ukudla kwezitshalo
Akukabikho ucwaningo oluningi olwenziwe okwamanje mayelana nokuphakela izinja okusekelwe ezitshalweni. Njengama-omnivores, izinja kufanele zikwazi ukuzivumelanisa nokugaya ukudla okuphekwe kahle kwemifino okuqukethe imisoco ebalulekile evame ukutholakala enyameni. Olunye ucwaningo lwathola ukuthi ukudla kwemifino okuklanywe ngokucophelela kulungele ngisho nezinja ezisebenzayo zesihlibhi. Kodwa khumbula ukuthi akukona konke ukudla kwezilwane ezifuywayo okukhiqizwa ngendlela efanele. Ucwaningo olwenziwa e-USA lubonise ukuthi ama-25% okuphakelayo emakethe awaqukethe zonke izakhamzimba ezidingekayo.
Kodwa ukudla okwenziwa ekhaya kwemifino kungase kungazisizi izinja. Ucwaningo lwaseYurophu olwenziwa ezinjeni ezingu-86 lwathola ukuthi ezingaphezu kwengxenye zazintula amaprotheni, ama-amino acid abalulekile, i-calcium, i-zinc, namavithamini D no-B12.
Kuyafaneleka futhi ukucabangela iqiniso lokuthi ukuhlafuna amathambo nenyama kungaba nomthelela omuhle ekuziphatheni kwezinja, futhi kube inqubo ejabulisayo nephumuzayo kuzo. Ngenxa yokuthi izinja eziningi ezifuywayo zivame ukushiywa zodwa ekhaya futhi ziba nemizwa yesizungu, la mathuba angaba yinzuzo kakhulu esilwaneni sakho.
