Ngisho nasemakhazeni okushisa asebusika abandayo, izinja zingathinta phansi ngezidladla zazo ezingenalutho ngaphandle kokuhlushwa yiqhwa. Baphumelela ngenxa ye-heater eyinkimbinkimbi, kuchaza abacwaningi baseJapane ephephabhukwini elithi “Veterinary Dermatology”. Isebenza njengohlelo lokushintshanisa ukushisa: igazi elifudumele, elingenayo lishisisa igazi elibuyayo ezidladleni, ligcine inja ifudumele nezidladla zihlala zipholile.
Iphampu yokushisa esidladleni
Besebenzisa i-electron microscopy, abacwaningi bathola ukuthi imithambo nemithambo yezidladla zezinja kusondelene ngokuphawulekayo. Lokhu kuvumela ukushisa okuvela egazini elinomoya-mpilo emithanjeni evela enhliziyweni ukuthi kudlulisele kalula egazini elingenawo umoya-mpilo emithanjeni eke yahlangana ngaphambili nendawo ebandayo. Igazi eliphuma emithanjeni libuyela emuva lifudumale lafika enhliziyweni yenja futhi lisuka lapho langena emgudwini wegazi omaphakathi.
Isimiso dolphin kanye duck
"Bekungaziwa ngaphambilini ukuthi inja isebenzisa ukushintshaniswa kokushisa," kusho uThomas Ruf we-Research Institute for Wildlife Ecology e-Vetmeduni Vienna. Kwezinye izilwane, noma kunjalo, lesi senzakalo siyaziwa - isibonelo ku-dolphin, esisebenzisa ku-fin, ekhaleni lenja kanye nenyamazane, kanye nasonyaweni lwedada. Ngaphandle kwalokho, amadada angancibilika uma emile eqhweni isikhathi eside. Bagcina kanjalo izinga lokushisa lonyawo lwabo ku-zero degrees.”
Izilwane zineqhinga eliyingqayizivele lokubonga iqiniso lokuthi izicubu azilimele. “Ukwakheka kwezitho ezithintekile kuyashintsha ngokuya ngesizini. Ekwindla, izilwane zigcina amafutha e-mono- kanye ne-polyunsaturated amaningi njengamafutha ezinhlanzi, azenza zikwazi ukuzivumelanisa nezimo ngendlela efanele,” kuchaza uRuf. Izilwane ezilala ebusika ziphumelela ukujwayela umzimba wonke ngokuvumelana nesimiso esifanayo. Ekwindla, isibonelo, ama-marmot abheka ngokukhethekile izitshalo ezinamafutha angenalutho - futhi ebusika azinankinga yokupholisa kuze kufike kumadigri amabili ewonke.
Ezinye izinja azifakwa ebusika
Ngokwesimiso esifanayo nesempisi yamadlozi, izinga lokushisa lezidladla zezinja nalo lehla libe kuqanda lapho kubanda. Nokho, lokhu akusebenzi kuwo wonke umuntu uhlobo lwenja. “Ezinye izinja azikufanelekele ukukhithika neqhwa ngenxa yokuthi ziye zafuywa ngenxa yezinye izici,” kusho umholi wocwaningo. Kulokhu, okukhethekile amabhuzu ebusika ngoba izinja zingasiza. Banikeza ukufakwa okungeziwe futhi abanikezeli nje ukuvikelwa emakhazeni, kodwa futhi kusukela kusawoti womgwaqo kanye ne-grit.
