Kodi agalu amatuwa liti?

Nthawi zambiri mumatha kuwona chiweto chokhala ndi mlomo woyera kapena mbali, koma sizingatheke kuweruza momveka bwino kuti muli ndi galu wokalamba patsogolo panu. Tsitsi laimvi la agalu siloyenera kwa ana agalu, koma nyama zazikulu sizikhalanso za imvi.

Kodi agalu amasanduka imvi bwanji?

Pali lingaliro lakuti agalu, monga anthu, amasanduka imvi akafika msinkhu winawake. Agalu akuluakulu - kuyambira zaka 6, zapakati - kuyambira 7, ndi ziweto zazing'ono kuyambira zaka 8. Koma izi sizowona kwathunthu, munthu anganene kuti sizowona konse. Agalu amasanduka imvi chifukwa cha zinthu zingapo nthawi imodzi. Choyamba, chobadwa ndi udindo wa maonekedwe a imvi. Kachiwiri, zambiri zimadalira mtundu ndi mtundu. Zatsimikiziridwa kuti ziphuphu bulauni, imvi yoyamba imatha kuwoneka zaka ziwiri.

Imvi mwa agalu, monga mwa anthu, sizigwirizana ndi zaka kapena thanzi.

Zomwe zimayambitsa imvi mwa agalu

Palibe deta yeniyeni pazomwe zimayambitsa imvi mu zinyama, koma pali malingaliro angapo, omwe ali ndi ufulu wokhalapo.

1. Kusintha kumachitika mu kapangidwe ka tsitsi - mpweya umapezeka pakati pa ma fibrils a keratin. Kuwala kukakhala paubweya, izi zimapanga chithunzithunzi cha imvi.

2. Mu thupi la nyama, kupanga ma melanocyte kumachepa, ntchito yawo imaletsedwa, zomwe zimapangitsanso kuti malaya asinthe.

3. Tsitsi la tsitsi limatulutsa hydrogen peroxide yochepa, imaphwanyidwa pang'onopang'ono, zomwe zimabweretsa imvi.

Pali zinthu zambiri zomwe zimapangitsa kuti mtundu wa nyama usinthe. Asayansi sakudziwabe bwinobwino chimene chimayambitsa imvi mwa agalu.

Mpaka pano, atha kutsimikizira izi chifukwa chanthawi zambiri kupanikizika mu nyama (mosasamala zaka, mtundu ndi mtundu), mphuno imayamba kukhala imvi. Zowona, izi sizilinso axiom: pali agalu omwe imvi zawo zimayambira kumbali kapena kumbuyo. Mahomoni opsinjika maganizo, adrenaline ndi norepinephrine, ndi omwe amachititsa izi.

Kafukufuku wopangidwa ndi nyuzipepala yotchedwa Applied Animal Behavior Science adatsimikizira kuti imvi ndi khalidwe la nyama zamanjenje, kapena kwa omwe akukhala ndi nkhawa nthawi zonse, kapena agalu opitirira zaka zinayi.

Umboni, ndithudi, sunasonkhanitsidwe zambiri. Chitsanzo chinaphatikizapo agalu 400, osankhidwa mwachisawawa. Kuyang'ana kunkangowoneka kokha, anamnesis a nyama adasonkhanitsidwanso. Zotsatira zake, zotsatira zimawoneka motere:

• chiweto chili ndi thanzi kapena kudwala - izi sizimakhudza kuchuluka kwa imvi;

• agalu amasanduka imvi ali ndi zaka 4, ngati palibe zinthu zokhumudwitsa;

• kupsinjika ndi mantha kumabweretsa imvi mwa agalu amtundu uliwonse ndi mtundu ali ndi chaka chimodzi.
