Akuti chiwerengero cha ma vegans ku UK chawonjezeka ndi 360% pazaka khumi zapitazi, ndipo anthu pafupifupi 542 akhala osadya nyama. Angerezi ndi mtundu wa anthu okonda nyama, ndipo ziweto zimapezeka pafupifupi 000% ya nyumba, ndi agalu pafupifupi 44 miliyoni ku UK. Ndizachilengedwe kuti pamitengo yotere, chikoka cha veganism chimayamba kufalikira ku chakudya cha ziweto. Zotsatira zake, zakudya zamasamba ndi agalu zamasamba zidapangidwa kale.
Amphaka ndi nyama zachilengedwe, zomwe zikutanthauza kuti amafunika kudya nyama kuti apulumuke, koma agalu amatha kukhala ndi zakudya zochokera ku zomera - ngakhale izi sizikutanthauza kuti muyenera kuika chiweto chanu pazakudya zimenezo.
Agalu ndi mimbulu
Galu wapakhomo kwenikweni ndi kagulu kakang'ono ka imvi wolf. Ngakhale kuti zimasiyana kwambiri m’njira zambiri, mimbulu ndi agalu amathabe kuswana n’kubala ana odalirika komanso obereka.
Ngakhale mimbulu imvi ndi aleki opambana, zakudya zawo zimatha kusintha kwambiri malinga ndi chilengedwe ndi nyengo. Kafukufuku wa nkhandwe ku Yellowstone Park ku US awonetsa kuti chakudya chawo chachilimwe chimaphatikizapo makoswe ang'onoang'ono, mbalame, ndi zinyama zamsana, komanso nyama zazikulu monga mphalapala ndi nyulu. Zimadziwika, komabe, kuti pamodzi ndi izi, zomera, makamaka zitsamba, zimakhala zofala kwambiri m'zakudya zawo - 74% ya zitsanzo za zitosi za nkhandwe zimakhala nazo.
za mimbulu anasonyeza kuti kudya monga chimanga ndi zipatso. Vuto limakhala chifukwa maphunziro nthawi zambiri samayerekeza kuchuluka kwa zakudya za nkhandwe zomwe zimakhala ndi zomera. Choncho, n'zovuta kudziwa momwe mimbulu ya omnivorous ndi agalu apakhomo alili.
Koma, ndithudi, agalu sali ngati mimbulu m’chilichonse. Galuyo akuganiziridwa kuti adawetedwa zaka 14 zapitazo - ngakhale umboni waposachedwapa umasonyeza kuti izi zikhoza kuchitika zaka 000 zapitazo. Zambiri zasintha panthawiyi, ndipo m'mibadwo yambiri, chitukuko cha anthu ndi zakudya zakhala zikukhudzidwa kwambiri ndi agalu.
Mu 2013, ofufuza a ku Sweden adatsimikiza kuti genome ya galuyo ili ndi code yowonjezereka yomwe imapanga puloteni yotchedwa amylase, yomwe ndi yofunika kwambiri pogaya wowuma. Izi zikutanthauza kuti agalu ali bwino kuwirikiza kasanu kuposa mimbulu pogaya wowuma—mumbewu, nyemba, ndi mbatata. Izi zikhoza kusonyeza kuti agalu apakhomo akhoza kudyetsedwa mbewu ndi mbewu. Ofufuzawo adapezanso mtundu wa enzyme wina wofunikira pakugayidwa kwa wowuma, maltose, mwa agalu apakhomo. Poyerekeza ndi mimbulu, enzyme imeneyi mwa agalu ndi yofanana kwambiri ndi yamtundu wa herbivores monga ng'ombe ndi omnivores monga makoswe.
Kusintha kwa agalu ku chakudya chochokera ku zomera panthawi yoweta kunachitika osati pamlingo wa michere. Mu nyama zonse, mabakiteriya m'matumbo amatenga nawo gawo pakugaya chakudya kumlingo wina. Zapezeka kuti gut microbiome mwa agalu ndi yosiyana kwambiri ndi mimbulu - mabakiteriya omwe ali mmenemo amatha kuthyola chakudya chamagulu ndipo mpaka kumapanga amino acid omwe amapezeka mu nyama.
Kusintha kwa thupi
Mmene timadyetsera agalu athu n’zosiyananso kwambiri ndi mmene mimbulu imadyera. Kusintha kwa zakudya, kuchuluka ndi zakudya zabwino panthawi yoweta kunapangitsa kuchepa kwa kukula kwa thupi ndi kukula kwa mano a agalu.
asonyeza kuti ku North America agalu oŵetedwa amakonda kuduka mano ndi kuthyoka kwambiri kuposa mimbulu, ngakhale kuti amadyetsedwa zakudya zofewa.
Kukula ndi mawonekedwe a chigaza cha galu chimakhudza kwambiri luso lawo lotafuna chakudya. Kukula koswana agalu okhala ndi milomo yaifupi kukusonyeza kuti tikusiya kuyamwa agalu apakhomo kuti asadye mafupa olimba.
Chakudya chobzala
Sipanakhalepo kafukufuku wochuluka wokhudza kudyetsa agalu ku zomera. Monga omnivores, agalu ayenera kutha kuzolowera ndikugaya zakudya zamasamba zophikidwa bwino zomwe zimakhala ndi michere yofunika yomwe imapezeka ku nyama. Kafukufuku wina adapeza kuti chakudya chamasamba chopangidwa mwaluso ndi choyenera ngakhale agalu ochita masewera olimbitsa thupi. Koma kumbukirani kuti si chakudya chonse cha ziweto chomwe chimapangidwa m'njira yoyenera. Kafukufuku ku USA adawonetsa kuti 25% yazakudya pamsika zilibe michere yonse yofunikira.
Koma zakudya zamasamba zopanga kunyumba sizingakhale zabwino kwa agalu. Kafukufuku wina wa ku Ulaya wa agalu 86 anapeza kuti oposa theka analibe mapuloteni, ma amino acid ofunika kwambiri, calcium, zinki, ndi mavitamini D ndi B12.
Ndikoyeneranso kuganizira mfundo yakuti kutafuna mafupa ndi nyama kungakhudze khalidwe la agalu, komanso kukhala njira yosangalatsa komanso yopumula kwa iwo. Chifukwa chakuti agalu ambiri amasiyidwa okha kunyumba ndipo amakhala osungulumwa, mwayi umenewu ungakhale wopindulitsa kwambiri kwa ziweto zanu.
