Bhala uhlu lwezizathu zezolimo ezenza ukuba izimvu zenziwe izilwane ezifuywayo
Context:Cishe izimvu ziyinzalo ye-mouflon yasendle yaseYurophu nase-Asia, kuyilapho i-Iran iyisizinda sokutholwa kwezimvu. Enye yezilwane zokuqala ezasetshenziselwa ukulima, izimvu zikhuliselwa ama-fleeces, inyama (iwundlu, i-hogget noma i-mutton) nobisi. Uboya bezimvu buyisilwane esisetshenziswa kakhulu, futhi kuvame ukuvunwa ngokuqoshwa. Emazweni e-Commonwealth, inyama yezimvu ibizwa ngokuthi iwundlu uma ivela ezilwaneni ezisencane nenyama yemvu uma ivela kwezikhulile; e-United States, inyama yezilwane ezindala nezincane ngokuvamile ibizwa ngokuthi iwundlu. Izimvu zisabalulekile namuhla ngenxa yoboya nenyama yazo, futhi ngezinye izikhathi zifuyelwa izikhumba, njengezilwane zobisi, noma njengezilwane eziyimodeli yesayensi.
Nasi uhlu lwezizathu zezolimo ezenza ukuba izimvu zenziwe izilwane ezifuywayo:  * Uboya - Uboya bezimvu buyi - fibre yezilwane esetshenziswa kakhulu futhi ngokuvamile buvunwa ngokugundwa * Inyama - Izimvu zitholakalela ukudla emazweni eCommonwealth (okuthiwa iwundlu uma zivela ezilwaneni ezisencane nenyama yemvu uma zivela ezilwaneni ezindala) nase-United States (inyama evela ezilwaneni ezindala nezincane ngokuvamile ibizwa ngokuthi iwundlu) * Ubisi - Izimvu ngezinye izikhathi zifuywa njengezilwane zobisi
