Konke mayelana nezinja zama-albino

Uma ucabanga ukuthola inja futhi unentshisekelo ezinjani ezingama-albino ezinamajazi azo amahle alula namehlo aphinki alutshwayo, awuwedwa esifisweni sakho - abathandi bezilwane ezifuywayo abaningi bamukela izilwane ezinjalo emindenini yabo.

Kodwa-ke, ngaphambi kokuba uthole inja ye-albino, kufanele ufunde ngokucophelela izici zalesi simo esinzima.

Yini i-albinism?

Ubu-Albinism ezinjeni - nanoma yiluphi olunye uhlobo lwezilwane - akulona uphawu lohlobo, kodwa ukuguqulwa kofuzo okungajwayelekile okubizwa ngokuthi i-tyrosinase-positive (complete albinos) kanye ne-tyrosinase-positive (partial albinos) albinism.

Ubu-albino bubangela ukuntuleka ngokuphelele kombala obala, okuhlanganisa esikhunjeni, ejazini, emehlweni, kanye nasemithanjeni yegazi, okuyenza ibe bomvu. Ngakho-ke, omunye umehluko wesici phakathi kwenja yangempela ye-albino nenja enoboya obumhlophe amehlo e-pink. Isilwane esinoboya obumhlophe sinephrofayili yofuzo yokushintsha umbala omhlophe noma singase sibe i-albino ngokwengxenye, kuyilapho inja ye-albino yangempela ayinalo nhlobo umbala.

I-National Wildlife Federation iyachaza: “Akuzona zonke izilwane eziphaphathekile kunokujwayelekile ezingama-albino. Kwezinye, umbala wombala awukho yonke indawo ngaphandle kwamehlo, into eyaziwa yizazi zezinto eziphilayo eziyibiza ngokuthi i-leucism. Ngakho-ke, inja emhlophe qhwa enamehlo aluhlaza okwesibhakabhaka, njenge-Siberian Husky, ayibhekwa njenge-albino.

Ukuze lesi simo sibonakale enzalweni, bobabili abazali kufanele babe abathwali bofuzo lwama-albinism. Kungenzeka ukuthi izinja ezimbili ezimnyama eziphethe isakhi sofuzo esinamandla zingakhiqiza umdlwane oyi-albino lapho zikhwelana.

Kodwa-ke, ubu-albinism buvame ukuvama kakhulu ezinhlotsheni ezithile zezinja, njenge-Collies ne-Great Danes, futhi ngezinye izikhathi ubu-albinism obuyingxenye buvela ngesimo samabala. Ngokwesibonelo, ungase ubone amachashaza amhlophe esifubeni noma ekhanda lesilwane, ngokuvamile okubonisa ukuba khona kwesakhi sofuzo, kodwa inja enjalo ayibhekwa njenge-albino yangempela.

Izinkinga zempilo

Njengoba izinja ze-albino zingenayo i-melanin, okuthi, ngaphezu kokunikeza umbala, futhi idonsa imisebe yelanga, i-photosensitive (okungukuthi, izwela kakhulu ekukhanyeni kwe-ultraviolet) ngakho-ke kufanele ivikelwe ekukhanyeni kwelanga. “Uma inja kufanele ibe ngaphandle phakathi namahora ashisa kakhulu ilanga,” kweluleka i-PetMD, “abanikazi bangasebenzisa izesekeli ezifana nezingubo zokuzivikela ze-UV, amajakhethi nezigqoko.” Uma uthola isilwane esifuywayo esiyi-albino, kuzodingeka futhi uthengele izinja izibuko zelanga futhi uqaphele kakhulu lapho uhamba ukuze uvikele amehlo aso.

Enye inkinga ehambisana nempilo yezinja ezingama-albino ukulimala kwesikhumba. Njengabantu abanesikhumba esiphaphathekile, kufanele kuqashelwe ngokukhethekile ukuze kuvinjelwe ukuchayeka elangeni ngokweqile, okungaholela ekushisweni yilanga noma umdlavuza wesikhumba, kuhlanganise ne-melanoma. Ngaphezu kokugqoka izibuko zezinja, lungiselela inja yakho ukuhamba emoyeni omusha ngokugcoba isikrini selanga ngendlela efanele. (Kodwa thintana nodokotela wakho wezilwane kuqala ukuze uthole ukuthi yimuphi umkhiqizo ongawuthenga nokuthi ungawusebenzisa kanjani.) Kukhona imithi yokuvikela ilanga enzelwe izinja ngokukhethekile, futhi imithi yokuvikela ilanga yezingane ingase ibe inketho enhle. Qaphela ukuthi izithako ezithile zezimonyo zinobuthi ezinjeni: gwema noma isiphi isikrini selanga esiqukethe i-PABA (para-aminobenzoic acid).

Ngaphezu kwalokho, umphakathi wezokwelapha ukhathazekile ngokuthi ubu-albinism bungabangela izithulu ezinjeni nakwezinye izilwane. Nokho, ngokukaDkt. George M. Strain, uprofesa waseLouisiana State University School of Veterinary Medicine ochwepheshe bokungezwa kwezinja namakati, akukho ukuhlobana phakathi kwakho kokubili: “I-Albinism, lapho ama-melanocyte [amangqamuzana abangela ukukhiqizwa kwe-melanin. ] zikhona, kodwa enye yama-enzyme anesibopho sokukhiqiza i-melanin (tyrosinase) ayikho noma inciphile, ayihlobene nokungezwa. UDkt. Stein uphawula ukuthi lokhu kuyasebenza nakubantu abangama-albino, egcizelela ukuthi ubuthulu akuwona umphumela we-albinism.

Isimo sofuzo esingandile nesingaqondakali njenge-albinism akufanele sikuvimbe ekutholeni umdlwane wamaphupho akho. Ngokunakekelwa okufanele nokuqonda izidingo zezempilo zomngane wakho onoboya, impilo yenu ndawonye izokwanelisa futhi ijabule.
