Yoqut qoramollari — Saxa Respublikasidagi Arktik shimolida oʻstiriladigan qoramol piyodasi. Ular haddan tashqari chidamliligi va muzlash haroratiga bardoshliligi bilan ajralib turadi.

Taʼrif

Yoqut qoramollari nisbatan oz miqdorda qolgan. Bu sigirlar quruq joylarda 110 va 112 sm balandlikda, tirik vazni 350 dan 400 kg gacha, buqalar 115 dan 127 sm gacha va vazni 500 dan 600 kg gacha boʻladi^[1]^[2]. Ularning qisqa, kuchli oyoqlari va chuqur, ammo nisbatan tor koʻkragi bor. Ularning rangi turlicha. U qora, qizil yoki dogʻli boʻlishi mumkin. Aksariyat hayvonlarning orqa qismida oq dorsal chiziq bor, qorongʻu hayvonlarda esa shoxlar orasidagi sochlar koʻpincha qizgʻish jigarrang rangga ega^[2]^[3].

Katta qorin va uzun ovqat hazm qilish tizimi ularga oʻtdan ham samarali foydalanishga imkon beradi. Qisqa yaylov mavsumida ular teri osti yogʻini juda tez koʻpaytiradi va qishda yomon ozuqa sharoitida omon qoladi^[4]^[5]^[6].

Yoqut qoramollari sil, leykoz va brutsellyozga chidamliligini namoyish etadi.
