Ukuhlukana Phakathi Kwezinkomo Zobisi
Izinhlobo ezine eziyinhloko zobisi - ama-Holsteins, ama-Jerseys, ama-Ayrshires nama-Guernseys, ahluka ngokuvumelana nesisindo esibukhoma, ubisi nokukhiqiza ubisi, kodwa ukuhluka phakathi kohlobo oluthile kufana kakhulu.
Holstein cows are high-yielding dairy cows and comes in 'red' or black varieties.
I-Holsteins inezimpawu ezihlukile, ngokuvamile ezimnyama nomhlophe zimibalabala nakuba zibomvu nezimhlophe. Imfuyo enamandla neyindayo esukela ku-550 kuya ku-750 kg, enezinga eliphezulu lokukhiqiza ubisi, elilinganiselwa ku-8550 kg ngosuku lwama-305 lactation (isilinganiso esingama-28 litre / ngosuku).
Amazinga okushisa ubisi aphakathi kuka-3.0% kuya ku-4.2% kanti okuqukethwe kwamaprotheni kuyahluka kusuka ku-2.5% kuya ku-3.8%. Uma ukondla kungalinganiselwe noma izinga elibi, izinkomo ezinkulu ezakhiwe eHolstein zizobe zingaphansi. Ngokuvamile, ama-Holsteins asetshenziselwa izinhlelo zokutshala izihlahla ezinjengezinhlelo zezindlu ezinamandla noma emakamu avulekile.
Zondliwa inhlanganisela ehlanganisiwe egcwele ama-bore (utshani, utshani) futhi igxila (ezithengiwe-ezinamapulangwe eziphezulu kwamandla namaprotheni) ezixutshwe ngokusho komkhiqizo wobisi noma isiteji se-lactation. Ngenxa yokuthi ukuzalwa kwe-Holstein yiyona ndlela enkulu kunazo zonke zohlobo lwezobisi emhlabeni, inqwaba yezilonda ezitholakalayo ziyatholakala ekuqothulweni kokufakelwa. Lokhu kusho ukuthi kungenzeka ukuthi kugcinwe ukuthuthukiswa kwezakhi zofuzo ekukhiqizeni ubisi ngenkathi kuthuthukiswa izici ezifana nokuzala.
Jersey cows are small friendly animals producing milk with a very high butterfat content.
Izinkomo zaseJersey zincane, zinombala obomvu nomhlophe futhi zilinganiselwa ku-350 kuya ku-450 kg. Ubisi lwabo luvuthwe kakhulu kune-Holsteins, cishe ngo-5000 kg nge-lactation nakuba ubisi lweJer Jersey lunamazinga aphezulu ezinsimbi eziqinile; Amazinga anamafutha ayi-4.0% kuya ku-5.5% namaphesenti amaprotheni ububanzi kusuka ku-3.5% ukuya ku-4.5%. Izinkomo zaseJersey zinobubele obukhulu nakuba izinkunzi zaseJersey ziyaziwa ukuthi zidla.
Ama-Jerseys asetshenziswa kakhulu ohlelweni olusekelwe emadlelweni ngenxa yamandla abo okudla okudliwayo ngenkathi kudinga amancane amancane agxila ngenxa yezinga eliphansi lokukhiqiza ubisi.
