Zvese nezvembwa dzealbino

Kana uri kufunga nezvekuwana imbwa uye uchifarira imbwa dzealbino dzine mabhachi adzo akanaka emwenje uye maziso epingi anorarisa, hausi wega muchishuwo chako - vazhinji vanoda mhuka dzinovaraidza dzinotora mhuka dzakadaro mumhuri dzavo.

Zvisinei, usati wawana imbwa yealbino, unofanira kunyatsodzidza maitiro emamiriro ezvinhu akaoma.

Chii chinonzi albinism?

Albinism mumbwa - kana chero imwe mhuka yemhuka - haisi yerudzi rwemhando, asi isingawanzo genetic mutation inonzi tyrosinase-positive (complete albinos) uye tyrosinase-positive (partial albinos) albinism.

Albinism inokonzeresa kushaikwa kwemavara eruvara, kusanganisira muganda, bhachi, maziso, pamwe netsinga dzeropa, zvichiita kuti dzipingike. Naizvozvo, imwe yehunhu hwakasiyana pakati peimbwa chaiyo yealbino nembwa ine mvere chena maziso epingi. Mhuka ine mvere chena ine genetic profile yewhite pigmentation kana kuti inogona kunge iri albino, nepo imbwa yealbino chaiyo haina zvachose pigmentation.

National Wildlife Federation inotsanangura kuti: “Hadzisi mhuka dzose dzakacheneruka kupfuura dzenguva dzose dziri ma<em>albino. Mune dzimwe, pigment haipo kwese kwese kunze kwemumaziso, chiitiko chebiologist chinodaidza kuti leucism. Nokudaro, imbwa yechando-chena ine maziso ebhuruu, akadai seSiberian Husky, haifaniri kuonekwa sealbino.

Kuti chirwere ichi chiratidze muvana, vabereki vose vanofanira kuva vatakuri vejini realbinism. Zvinokwanisika kuti imbwa nhema mbiri dzinotakura recessive gene dzinogona kubereka mwana wealbino kana asangana.

Zvisinei, huarubhino hunowanzova hwakajairika mune dzimwe mhando dzembwa, dzakadai seCollies neGreat Danes, uye dzimwe nguva ma<em>albinism akasarura anooneka nenzira yemavara. Semuenzaniso, unogona kuona mavara machena pachipfuva kana musoro wemhuka, izvo zvinowanzoratidza kuvapo kwejini recessive, asi imbwa yakadaro haifungidziri albino yechokwadi.

Matambudziko ehutano

Sezvo imbwa dzealbino dzisina melanin, iyo, kunze kwekupa pigment, inotorawo mwaranzi yezuva, ndeye photosensitive (kureva, yakanyanya kujeka kune ultraviolet chiedza) uye saka inofanira kudzivirirwa kubva kune yakananga zuva. "Kana imbwa ichifanira kunge iri panze mukati memaawa ekupisa kwezuva," inopa zano PetMD, "varidzi vanogona kushandisa zvinhu zvakadai seUV-inodzivirira bodysuits, mabhachi, uye ngowani." Kana ukawana chipfuyo chealbino, uchadawo kutengera imbwa magirazi ezuva uye kungwarira zvakanyanya paunenge uchifamba kudzivirira kuona kwayo.

Rimwe dambudziko rine chekuita nehutano hwembwa dzealbino kukuvara kweganda. Sezvinoita vanhu vane ganda rakacheneruka, kutariswa kwakanyanya kunofanirwa kutorwa kudzivirira kushata kwezuva zvakanyanya, izvo zvinogona kukonzera kupisa kwezuva kana kenza yeganda, kusanganisira melanoma. Mukuwedzera pakupfeka magirazi embwa, gadzirira imbwa yako kufamba mumhepo yakachena nekushandisa sunscreen zvakanaka. (Asi tanga wabvunza chiremba wako wemhuka kuti uone kuti ndechipi chigadzirwa chaungatenga uye kuti ungachishandisa sei.) Kune mishonga yekudzivirira zuva yakagadzirirwa imbwa, uye vana vanogona kuva sarudzo yakanaka. Ziva kuti zvimwe zvizorwa zvine chepfu kune imbwa: dzivisa chero sunscreen ine PABA (para-aminobenzoic acid).

Pamusoro pezvo, vezvekurapa vari kutyira kuti albinism inogona kukonzera kusanzwa kwembwa nedzimwe mhuka. Zvisinei, maererano naDr. George M. Strain, purofesa weLouisiana State University School of Veterinary Medicine uyo anonyanya kudzidzira kusanzwa kwembwa nekatsi, hapana kubatana kuripo pakati pezviviri izvi: “Albinism, umo melanocyte [masero anokonzera kugadzirwa kwe melanin. ] dziripo, asi imwe ye enzymes inokonzera kugadzirwa kwe melanin (tyrosinase) haipo kana kuderedzwa, isingabatanidzi nekunzwa. Dr. Stein anoti izvi zvinoshandawo kune katsi dzealbino, achisimbisa kuti kusanzwa hakusi mhedzisiro yealbinism.

Iyo isingawanzo uye isinganzwisisike genetic mamiriro akaita sealbinism haifanire kukumisa kubva pakutora imbwa yezviroto zvako. Nekutarisirwa kwakanaka uye nekunzwisisa kwehutano hweshamwari yako ine furry, hupenyu hwenyu pamwe chete huchave hunogutsa uye hunofadza.
