• Kodi chimachitika ndi chiyani ku thupi la nyama?
• Zitsanzo za nyama zobisala
• Mitundu ya nyama zomwe zimabisala

Pulogalamu yakubisala Ndi njira yomwe nyama zina zimachepetsera mphamvu zawo munthawi ya chaka, chifukwa zimakhalabe ndi hypothermia kwa miyezi ingapo. Mwachitsanzo: chimbalangondo, mileme, buluzi.

Njira yozizira yomwe imabisala imawoneka chifukwa chakutha kwa nyama zina kuzolowera chilengedwe. Kutsika kwakukulu kwa kutentha kumayambitsa kusowa kwa chakudya (minda itha kudzazidwa ndi ayezi ndi chipale chofewa), ndipo imatha kupha. Kutha kubisala kudachitika chifukwa cha kuzizira kwadzaoneni.

Kodi chimachitika ndi chiyani ku thupi la nyama?

Nyama zimakhala ndi matupi awo okonzeka kuti azichita hibernation, ndipo milungu ingapo asanayambe kupanga mafuta zomwe zidzaloleza kukana nthawi imeneyo. Kuphatikiza apo, munthawi yapitayi nyamazo zimakonza mosamala pogona pomwe zizikhalamo miyezi ija.

Kenako, kutentha kwa mumlengalenga kukatsika mpaka kufika poyerekeza ndi kutsika, kugona kumachitika kumene nyamayo imatha kuwoneka yakufa. Nthawi zina nyamazo zimakhala ndi mawonekedwe kuti ziziteteze kuzizira, monga mpira.

Physiologically, hibernation imaphatikizapo kupeza kwa dormancy kapena ulesi wozizira, womwe umakhala ndi vuto lalikulu mthupi kuchepa kwa kugunda kwa mtima, kugunda kwa mtima kumatha kuchepetsedwa mpaka 80%, mu 50% mlingo wa kupuma ndi madigiri anayi kapena asanu kutentha. Nyama imasiya kuchita zinthu zina zomwe zimakhala zofunikira kwambiri, monga kudya, kumwa, kuchita chimbudzi kapena kukodza.

Pa nthawi yozizira, Mitundu yonse ili ndi masewera olimbitsa thupi a dzuka ndi kayendedwe komwe kutentha kwa thupi kumawonjezeka, kumafuna kugwiritsa ntchito mphamvu zapadera munthawi yogona, yomwe ndi nthawi yomwe mphamvu zochulukirapo zimagwiritsidwa ntchito.

Masika akafika, nyamazi zimabwerera kutentha thupi ndikubwerera m'moyo wabwinobwino, nthawi zambiri zimachepetsa kwambiri. Mwambiri mphindi iyi imagwirizana ndi kuyamba kwa nyengo yokwanira.

Zitsanzo za nyama zobisala

Mitundu ya nyama zomwe zimabisala

Sikuti nyama zonse zimabisala, koma okhawo omwe amakhala m'malo ozizira, makamaka nyengo yozizira imabweretsa kusamvana kwamphamvu.

Kusiyanitsa kumachitika nthawi zambiri pakati pa kubisala kwa:

• Zinyama zopanda magazi (nthawi zambiri nyama zing'onozing'ono monga tizilombo, nkhono, mbozi kapena nsomba, zomwe zimakhala ndi kutengera mitundu ina yomwe imalola kuti izitha kutentha);
• Nyama zamagazi ofunda (zomwe zimasokonekera kwambiri chifukwa cha kutentha kochepa, pakati pake pali zinyama zobisalira, nyama zowononga tizilombo ndi agologolo).

• Komanso: Nyama zamagazi otentha komanso ozizira

Itha kukutumikirani:

• Zitsanzo za Nyama Zokwawa
• Zitsanzo Zosamutsa Nyama
• Zitsanzo za nyama zapakhomo
