Izici Ezithinta Ikhwalithi Yenyama Yenkomo
Inyama yenkomo iwumthombo omkhulu wamaprotheni adliwa kakhulu amaqembu ahlukahlukene abantu. Ikhwalithi yenyama yenkomo ithonya kakhulu ukunambitheka kwayo, ukuthungwa kwayo, kanye nokudla okunempilo. Ngakho-ke, izici eziningi zingathonya ikhwalithi yenyama yenkomo, kusukela ku-genetics kuya ekuhlatshweni nasekugcinweni kwayo. Lesi sihloko sizoxoxa ngalezi zici ngokuningiliziwe.
1. Izici Zofuzo
Izici zofuzo zidlala indima ebalulekile ekunqumeni ikhwalithi yenyama yenkomo. Nazi ezinye izici zofuzo ezithonya ikhwalithi yenyama:
a. Uhlobo lwezinkomo
Uhlobo lwezinkomo luthinta kakhulu ikhwalithi yenyama yenkomo. Ezinye izinhlobo zizalelwe ngqo ukukhiqiza inyama esezingeni eliphezulu. Isibonelo, izinkomo zaseJapane Wagyu zaziwa ngenyama yazo ethambile kakhulu ene-marbling ephezulu (ukungena kwamafutha emisipheni), kuyilapho izinkomo ze-Angus zaziwa ngenyama yazo emnandi ene-marbling efanayo, kodwa engeyinkimbinkimbi kangako.
b. Ukukhethwa Kwezakhi Zofuzo
Ngomzamo wokuthuthukisa ikhwalithi yenyama, abafuyi bavame ukusebenzisa amasu okukhetha izakhi zofuzo ukuze bazale izinkomo ezinezimpawu ezinhle kakhulu. Lokhu kukhetha kungahlanganisa izici ezahlukahlukene, njengesilinganiso sokukhula, ukusebenza kahle kokudla, kanye nekhwalithi yemisipha.
2. Ukudla Okunomsoco Nokudla
Ukudla okunikezwa izinkomo kuthinta kakhulu ukwakheka kwenyama ekhiqizwayo. Ukunikeza ukudla okuseqophelweni eliphezulu nokulingene kuzokhiqiza inyama yenkomo esezingeni eliphezulu. Izinto eziningana okufanele uzicabangele kulokhu yilezi:
a. Ukwakheka Kokuphakelayo
Ukudla kwezinkomo ngokuvamile kuqukethe utshani, i-silage, okusanhlamvu, kanye nokudla okuxubile. Le nhlanganisela yezakhamzimba ibalulekile ekunqumeni ikhwalithi yokugcina yenyama. Isibonelo, izinkomo eziphakelwa ukudla okusanhlamvu okuningi zizokhiqiza inyama enamafutha amaningi kanye ne-marbling engcono kunotshani obuphakelwa izinkomo.
b. Izithasiselo namavithamini
Ngaphezu kokudla okuyinhloko, ukuhlinzeka ngezithasiselo namavithamini nakho kubalulekile ekuthuthukiseni impilo yenyama yenkomo kanye nekhwalithi yenyama. Izithasiselo ezithile, njengeprotheni eyengeziwe, amaminerali, namavithamini athile, zingathuthukisa ukukhula kwemisipha kanye nekhwalithi yenyama.
3. Ukuphathwa Kwemfuyo
Imikhuba yokuphatha imfuyo inomthelela omkhulu ekhwalithini yenyama yenkomo. Ukuphathwa kwemfuyo okuhle kuphumela ezinkomeni ezinempilo kanye nemikhiqizo yenyama esezingeni eliphezulu.
a. Ukuhlanzeka Nempilo
Indawo ehlanzekile yepulazi kanye nempilo yezinkomo egciniwe kuzovimbela izifo nezifo ezinganciphisa ikhwalithi yenyama. Ukugoma njalo, ukulawulwa kwezifo, kanye nokuhlolwa kwempilo yezinkomo kubalulekile.
b. Ukucindezeleka
Ukucindezeleka ezinkomeni, kungakhathaliseki ukuthi kungenxa yendawo ezungezile, ukunakekelwa, noma ukuthuthwa, kungathinta ikhwalithi yenyama. Ukucindezeleka ngokomzimba nangokwengqondo kungaholela esimweni esaziwa ngokuthi inyama emnyama, eqinile, neyomile (DFD), okubangelwa amazinga aphansi e-glycogen emisipheni yenkomo. Ngakho-ke, ukunciphisa ukucindezeleka kubalulekile ekuphathweni kwemfuyo.
4. Ubudala kanye nesisindo
Ubudala kanye nesisindo senkomo uma ihlatshwa nakho kudlala indima ekunqumeni ikhwalithi yenyama ekhiqizwayo.
a. Ubudala
Ngokuvamile, izinkomo ezincane zinenyama ethambile kakhulu kunezinkomo ezindala. Inkomo encane ivame ukuba nokunambitheka okuthambile. Izinkomo ezindala zivame ukuba nenyama eqinile futhi zinambitheka kakhulu, okungase kungathandeki kwabanye abathengi.
b. Isisindo Somzimba
Isisindo somzimba wenkomo sihlobene nokuqukethwe kwamafutha enyama. Isisindo esifanele sokuhlatshwa ngokuvamile siphakathi kuka-400 no-600 kg, kuye ngohlobo kanye nohlobo lokudla. Izinkomo ezinesisindo esifanele zizokhiqiza inyama enhle nethambile.
5. Inqubo Yokusika Nokuphatha
Ukuhlatshwa kwezinkomo kumele kwenziwe ngokucophelela ukuqinisekisa ukuthi ikhwalithi yenyama iyagcinwa. Nazi ezinye izinto okufanele uzicabangele:
a. Amasu Okusika
Amasu okuhle okusika anganciphisa umonakalo ezicutshini zemisipha futhi aqinisekise ukusatshalaliswa kwegazi ngokulinganayo, avimbele inyama ekuboleni. Ukusika okubi kungaholela ekusabalaleni kwamagciwane kanye nokungcola okuhlukahlukene.
b. Ukuphatha ngemva kokusika
Ukuphathwa kwenyama ngemva kokuhlatshwa, njengokupholisa, ukuguga, kanye nokugcinwa, kubalulekile. Ukupholisa ngokushesha ngemva kokuhlatshwa kungavimbela ukukhula kwamagciwane futhi kugcine ubumnandi. Inqubo yokuguga ingathuthukisa ubumnandi kanye nokunambitheka. Ukugcinwa okufanele, kungakhathaliseki ukuthi kufrijiwe noma kuqandisiwe, kuzosiza ukugcina ikhwalithi yenyama kuze kube yilapho isilungele ukudliwa.
6. Faktor Lingkungan
Indawo lapho izinkomo zikhuliswa khona nayo ithonya kakhulu ikhwalithi yokugcina yenyama. Ezinye izici zemvelo okufanele uzicabangele yilezi:
a. Isimo sezulu
Isimo sezulu sithonya amazinga empilo kanye nokucindezeleka kwezinkomo. Izimo zezulu ezimbi kakhulu, kungaba kushisa kakhulu noma kubanda kakhulu, zingabangela ukucindezeleka ezinkomeni futhi zinciphise ikhwalithi yenyama. Ama-bioregulator alinganisela izinga lokushisa lomzimba kanye nenduduzo yezinkomo abalulekile.
b. IJografi
Izimo zomhlabathi kanye nekhwalithi yamanzi endaweni yezilwane nazo zinomthelela. Inhlabathi ecebile ngezakhamzimba kanye namanzi ahlanzekile kungasekela ukukhula kotshani nokudla okuseqophelweni eliphezulu, okuzodliwa yizinkomo, okuthinta ikhwalithi yenyama ekhiqizwayo.
7. Izifo
Izifo ezithinta izinkomo azigcini nje ngokunciphisa umkhiqizo wazo kodwa futhi zinganciphisa ikhwalithi yenyama. Ezinye izifo, njenge-bovine spongiform encephalopathy (BSE) noma isifo sezinkomo ezihlanyayo, zingenza inyama ingafaneleki ukudliwa. Ukusebenzisa izinyathelo eziqinile zokuphepha kanye nokugoma njalo kubalulekile ekuvimbeleni lezi zifo.
Isiphetho
Ikhwalithi yenyama yenkomo ithonywa izici ezahlukahlukene, okuhlanganisa izakhi zofuzo, ukudla okunomsoco kanye nokudla, ukuphathwa kwepulazi, ubudala kanye nesisindo sezinkomo, izinqubo zokuhlaba nokuphatha, indawo ezungezile, kanye nempilo yezilwane. Ingxenye ngayinye inegalelo elikhulu ekhwalithini yenyama ekhiqizwayo. Ngakho-ke, ukuqonda okuphelele nokuphathwa okufanele kwaleso naleso salezi zici kubalulekile ekukhiqizeni inyama yenkomo esezingeni eliphezulu ehlangabezana nezidingo zabathengi. Ngale ndlela ebanzi, abalimi bangaqinisekisa ukuthi inyama yenkomo ekhiqizwayo imnandi, ithambile, inempilo, futhi inomsoco kakhulu.
