5 izinja izinganekwane debunked ososayensi

Izinja zihlala nathi amashumi ezinkulungwane zeminyaka. Futhi okumangazayo nakakhulu ukuthi zingaki izinganekwane ezikhona ezizungeze lezi zilwane. Kodwa-ke, ngenhlanhla, isayensi ayimile, futhi phakathi namashumi eminyaka ambalwa edlule sifunde okwengeziwe ngezinja kunaseminyakeni eyinkulungwane edlule. Ngakho, yiziphi izinganekwane mayelana nezinja eziye zachithwa ososayensi?

Zingaphezu kwezinhlanu zalezi zinganekwane, kodwa sizoqala ngezinhlanu eziphezulu.

1. Kukhona izinhlobo zezinja ze-hypoallergenic. Nokho, lokhu kuyinganekwane, futhi kuyingozi empilweni yomuntu okholelwa kuyo. Alukho uhlu oluqashelwa ngokusemthethweni lwezinja ezingabangeli ukungezwani komzimba nezinto ezithile.

Kwesinye isikhathi ungafunda emithonjeni yezindaba ukuthi izinja ezinezinwele ezimahhadlahhadla (okungaphumi ngokwemvelo) noma ezingenaboya azibangeli ukungezwani komzimba nezinto ezithile. Futhi uma ukungezwani komzimba kubangelwa uboya kuphela, khona-ke izinja ezinjalo zingaba indawo yokuphuma kumuntu oguliswa yi-allergic. Kodwa ukungezwani komzimba akwenzeki eboyeni kuphela, kodwa nasezinjeni zezinja (kuhlanganise namathe), izinhlayiya ze-epidermis othulini, nokunye okunjalo. Futhi kulokhu, akunandaba ukuthi inja yakho inaluphi uhlobo lwejazi.

Ngakho-ke uma u-allergic, ungafundi izinhlu zezinhlobo ze-hypoallergenic. Kuhlakaniphe kakhulu ukufuna iseluleko sikachwepheshe ukuze unqume ukuthi yini ngempela oyizwayo.

2. Unyaka owodwa wempilo yenja ulingana neminyaka eyisikhombisa yokuphila komuntu.

Akukacaci ukuthi le nsumansumane iqhamukephi. Kodwa cishe ngawo-50s wekhulu lama-20, kwavela ulwazi lokuthi, njengoba isilinganiso sobude bokuphila komuntu siyiminyaka engaba ngu-70, nezinja - cishe iminyaka eyi-10, kunengqondo ukulinganisa unyaka owodwa wokuphila kwenja neminyaka eyisikhombisa yomuntu. .

Kodwa ososayensi ngokushesha bayingabaza indlela enjalo. Ngakho, u-A. Lebo wafinyelela esiphethweni sokuthi ngonyaka wokuqala wokuphila inja, njengokungathi, "iphila" iminyaka engu-15-20 yomuntu, ngonyaka wesibili ifinyelela "iminyaka yomuntu" yeminyaka engu-24, bese-1 unyaka ungalinganiswa neminyaka emi-4 yomuntu.

Kodwa manje ososayensi sebethathe indlela ehlukile njengejwayelekile. Okucabangela ubukhulu nohlobo lwenja. Phela, isilinganiso sobude bokuphila, kuye ngalezi zingxenye, singahluka: kokubili iminyaka engu-9 no-16. Futhi iminyaka engu-7 yenja ayilingani neminyaka engu-7 ye-pinscher encane.

Ngakho-ke, ososayensi bahlukanise izinja ngamaqembu ama-4 ngosayizi:

•       Incane (kufika ku-10 kg).
•       Okuphakathi (10 - 25 kg).
•       Okukhulu (25 - 45 kg).
•       Isikhulu (ngaphezu kwama-45 kg).

Abamele iqembu ngalinye bakhula ngejubane labo, ngakho ubuhlobo babo nobudala bomuntu buhlukile.

3. Izinja ezindala aziqeqeshiwe.

Yiqiniso, lokhu akulona iqiniso. Izinja zifunda zonke izimpilo zazo, futhi ngisho naseminyakeni yokuguga ngokweqile, kuyadingeka ukubhekana nesilwane esifuywayo ukuze kuvinjelwe ukuthuthukiswa kokuwohloka komqondo ongasenani noma ukwenza ukuphila kube lula kumngane onemilenze emine uma ukuwohloka komqondo kwenzeka. Yebo, izinja zeminyaka ehlukene zifunda ngendlela ehlukile, kodwa ukusho ukuthi akunangqondo ukuqeqesha inja endala akulungile.

4. Inja itshikizisa umsila lapho ijabule.

Lena inganekwane eyingozi engabiza kakhulu kulabo abakholelwa kuyo. Sesixoxe kabanzi ngalolu daba esihlokweni esihlukile. Lapha sikhumbula kuphela ukuthi ukutshikizisa umsila akulona uphawu lwenjabulo, kodwa lwenjabulo. Okungakhombisa imizwa eyahlukene. Kubandakanya ukulungela ukukhombisa ulaka.

Ngaphezu kwalokho, izingozi zezinkinga zengezwa kunoma yisiphi isigaba. Futhi imidlwane isadinga ukuphakelwa. Ngenxa yalokho, umzimba wenja uyancipha, futhi izifo zingavela ezingeke zivele ngokuvamile. Futhi akekho oye wakhansela inkinga yokuba khona kwenani elikhulu lezinja ezingenamsebenzi.
