Ukhula nini umdlwane, injanyana ibalwa nini njengomuntu omdala? Ukuguqulwa eminyakeni yomuntu kusiza ukuthola umuzwa weminyaka yenja.
Izinja ezinonyaka owodwa sezivuthiwe ngokocansi, kanti izingane ezineminyaka eyishumi ubudala sezivele zinezinwele ezimpunga ezizungeze imilomo yazo: umthetho osetshenziswa kaningi wesithupha othi “iminyaka yezinja + 7 = iminyaka yomuntu” awukwazi ukuba olungile. Abacwaningi baseMelika manje sebeshicilele ifomula entsha okufanele ukhiphe isibali ngokhiye we-logarithm: 16 ln(iminyaka yezinja) + 31 = iminyaka yomuntu.
Ayiyona inkimbinkimbi, kodwa inembe kakhudlwana. Ifomula isuselwe ezinguqukweni eziqondene neminyaka ethile ku-genome efanayo kubantu nasezinjeni. Akukhona nje kuphela ukuthi izinwele ziba mpunga futhi isikhumba sishwabene ngokuhamba kweminyaka, kodwa i-DNA ibuye ibonise izimpawu zokuguga.
Intuthuko ezinjeni nakubantu
Ifomula esanda kwakhiwa isiza ukwenza izigaba zokukhula ezinjeni nakubantu ziqhathanise: Umdlwane onamasonto ayisishiyagalombili ucishe ufane nowomntwana onezinyanga eziyisishiyagalolunye ubudala futhi uba namazinyo aqondile. Futhi umholi wocwaningo u-Trey Ideker manje unokuqonda okwengeziwe lapho inja yakhe eneminyaka eyisithupha ubudala iphelelwa umoya ngenkathi igijima: phela, njengomuntu, ngabe isivele isondela ku-60.
Umbuzo Ovame Ukubuzwa
Malini unyaka o-1 womuntu onyakeni wezinja?
Kusukela ngeminyaka yawo-1950, ukubala okudumile kokuthi inja indala kangakanani “eminyakeni yomuntu” kube ukuthi unyaka wenja ongu-1 ulingana neminyaka eyi-7 yomuntu.
Ineminyaka emingaki inja enonyaka owodwa ubudala?
Kuthiwa iminyaka eyisikhombisa yomuntu ilingana nonyaka owodwa empilweni yenja. Uma ufuna ukubala iminyaka yenja, kufanele kuphela uphindaphinde iminyaka yokuphila komngane onemilenze emine ngeyisikhombisa.
Kungani uphindaphinda iminyaka yezinja ngo-7?
Ngokohlaziyo lwezakhi zofuzo, izinja azigugi ngesivinini esingaguquki kunabantu. Umthetho owandile wesithupha weminyaka yezinja, ngokusho ukuthi unyaka owodwa uhambisana neminyaka eyisikhombisa yabantu, uthathwa abacwaningi base-US njengongalungile.
Yiziphi izinja eziguga kakhulu?
Izinhlobo zezinja ezincane eziphila isikhathi eside ikakhulukazi ngokwesilinganiso, isibonelo, i-Chinese Crested Dog, i-Dachshund, ne-Pomeranian - ziphila iminyaka engu-18. Izinhlobo ezinkulu ezifana ne-Irish Wolfhound, i-Leonberger, noma i-Dogue de Bordeaux zinesilinganiso seminyaka yokuphila esingafika ku-8 iminyaka.
Inkulu kangakanani inja endala?
Inja endala kunazo zonke emhlabeni
U-Australian Kelpie bitch uMaggie uthathe indawo. Washona ngo-2016 eneminyaka engu-30 ubudala. Wayephushe i-Australian Cattle Dog "Bluey" endaweni yesibili, eyayineminyaka engu-29 nezinyanga ezingu-5 ubudala, futhi yashona ngo-1939.
Ingabe inja eneminyaka engu-7 ubudala kakade isindala?
Ngokwesilinganiso, inja ibhekwa njengesikhulu kusukela eminyakeni eyisikhombisa kuya kweyisishiyagalolunye. Kulesi sigaba sokugcina sempilo, izidingo ezikhethekile eziningi zezinja ezindala kufanele zicatshangelwe. Ngokusekelwa nokunakekelwa okufanele, umngane wakho onemilenze emine angahlala eqinile futhi enempilo isikhathi eside.
Ingabe izinja ezindala ziyaxaka?
Ebudaleni, ikhono lokubona nokuzwa ikakhulukazi liyancipha. Izinguquko ekuziphatheni nazo zingaba umphumela lapho izinzwa ziwohloka. Lokhu kungase kube isizathu esenza inja yakho isabele ethukile futhi ikhathazeke kakhulu ezimweni ezithile, noma ngokuphambene nalokho: ikhululeke kakhulu.
Ingabe ukuqwasha kubonakala kanjani ezinjeni?
Ukulahlekelwa ukudla okuhambisana nokuncipha kwesisindo. Izinkinga zamalunga namathambo ngenxa yokulahlekelwa amathambo noma i-arthrosis: Lokhu ngokuvamile kusho ukuthi inja ayisathandi ukunyakaza noma ubuhlungu lapho iphakama futhi yehla. Ukuncipha noma ukulahlekelwa ukuzwa, ukubona, nokuhogela.
Izilwane zizizwa kanjani lapho zilaliswa?
Uma inja ikhishwe ngokomthetho, ngeke izwa ubuhlungu obungokomzimba. Akakuzwa ukufa kwakhe kuza. Izilwane zibulawa ngesibulali-zinzwa.
Yini okufanele ngiyenze uma inja yami ishonela ekhaya?
Ungakwazi futhi ukushiswa inja yakho endaweni yokushiswa kwezilwane ezifuywayo noma ucele udokotela wakho wezilwane ukuba alahle isidumbu. Uma inja yakho ishonela ekhaya, kuhle ukugcina umzimba upholile kuze kufike isikhathi sokungcwatshwa.
