Njengoba izinsuku ekhalendeni zisondela ekuvuneni, abalimi be-DTN Taxi Perspective banikeza imibiko yenqubekelaphambili futhi baxoxe ngokuthi babhekana kanjani nakho…
I-REDFIELD, Iowa (DTN) - Izimpukane zingaba inkinga emihlambini yezinkomo ngesikhathi sasentwasahlobo nasehlobo. Ukusebenzisa izilawuli ezinhle ngesikhathi esifanele kungasiza ekuzuzeni imbuyiselo ekutshalweni kwezimali.
"Amasu amahle okulawula izinambuzane angasiza ekuhlinzekeni ukulawula okuphumelelayo," kusho uGerald Stokka, udokotela wezilwane eNyuvesi yaseNorth Dakota State University kanye nochwepheshe wokuphatha imfuyo. Lokhu kusho ukulawula okulungile ngesikhathi esifanele nangesikhathi esifanele.
"Lapho ukhulisa amathole enyama yenkomo, izintwala kanye nokulawula izinambuzane ezindizayo ngaphambi kokuklama ngeke kusebenze futhi kubangele ukulahlekelwa kwezinsiza zokulawula izinambuzane," kusho uStoica. "Isikhathi nohlobo lokulawula izinambuzane kuncike ohlotsheni lwempukane."
Izimpukane zophondo nezimpukane zasolwandle ngokuvamile aziveli kuze kube sekuqaleni kwehlobo futhi azifinyeleli emngceleni wezomnotho wokulawula kuze kube maphakathi nehlobo. Izimpukane zophondo zimpunga futhi zibukeka njengezimpukane zendlu encane. Uma ziyekwa zinganakwa, zingahlasela imfuyo izikhathi ezifika ku-120,000 ngosuku. Phakathi namahora aphakeme, izimpukane ezingafika ku-4,000 zingaphila esikhumbeni senkomo esisodwa.
U-Elizabeth Belew, isazi sokudla kwezinkomo kwaPurina Animal Nutrition, uthe izimpukane zendwayimane zizodwa zingadla imboni yemfuyo yaseMelika imali efinyelela ku-$1 billion ngonyaka. “Ukulawula ukundiza kwezinkomo ekuqaleni kwesizini kungenza umehluko omkhulu ekulawuleni abantu isizini yonke,” kusho yena.
“Ukulunywa njalo kungabangela ubuhlungu nengcindezi enkomeni futhi kunganciphisa isisindo senkomo ngamakhilogremu angu-20,” kwengeza uStokka.
Izimpukane zobuso zibukeka njengezimpukane ezinkulu, ezimnyama. Ziyizimpukane ezingalumiyo ezidla indle yezilwane, umpe wezitshalo kanye noketshezi lwendle. Lezi zimpukane zingangena emehlweni ezinkomo futhi zibangele i-conjunctivitis. Lezi zibalo ngokuvamile ziba phezulu ngasekupheleni kwehlobo.
Izimpukane eziqinile ziyafana ngosayizi nezimpukane, kodwa zinezimpawu eziyindilinga ezizihlukanisa nezimpukane. Lezi zimpukane zidla igazi, ngokuvamile ziluma isisu nemilenze. Kunzima ukuzilawula ngemikhiqizo echithekile noma ejovwe.
Kunezinhlobo eziningana ezahlukene zezilawuli zendiza, futhi ezinye zingasebenza kangcono kunezinye ezimweni ezithile. Ngokuka-Belew, indlela esebenzayo nelula yokulawula izimpukane zophondo phakathi nenkathi yempukane iwukuphakela amaminerali aqukethe izilawuli zokukhula kwezinambuzane (IGRs), ezifanele zonke izigaba zezinkomo.
"Lapho izinkomo ezine-IGR zisebenzisa i-mineral, idlula esilwaneni bese ingena endle, lapho uphondo lwensikazi eselukhulile lundiza lubekela amaqanda. Kungcono ukondla izinsuku ezingama-30 ngaphambi kwesithwathwa sokugcina entwasahlobo kanye nezinsuku ezingama-30 ngemuva kwesithwathwa sokuqala ekwindla ukuze kuqinisekiswe ukuthi imfuyo ifinyelela emazingeni ahlosiwe.
UColin Tobin, usosayensi wezilwane e-NDSU's Carrington Research Center, uthe kuyasiza ukuhlola amadlelo ukuthola ukuthi yiziphi izimpukane ezikhona kanye nenani lazo. Ama-ear tag, aqukethe izibulala-zinambuzane ezidedelwa kancane kancane eboyeni besilwane njengoba sihamba, ayindlela enhle, kodwa akufanele asetshenziswe kuze kube yilapho izimpukane seziphezulu maphakathi noJuni kuya kuJulayi, esho.
Utusa ukuba kufundwe amalebula, njengoba amalebula ahlukene angase ahluke ngamanani okusetshenziswa, ubudala bezinkomo okungenzeka bushiwo, kanye nebanga lamakhemikhali lesithako esisebenzayo. Omaka kufanele basuswe lapho bengasavumelekile.
Enye indlela yokulawula i-potting compounds nezifutho zezilwane. Ngokuvamile zisetshenziswa ngokuqondile phezulu kwesilwane. Ikhemikhali iyamuncwa futhi izungeza wonke umzimba wesilwane. Le mithi ingakwazi ukulawula izimpukane kuze kube yizinsuku ezingu-30 ngaphambi kokuba ziphinde zisetshenziswe futhi.
“Ukuze kulawuleke kahle izimpukane, izifutho kufanele zisetshenziswe njalo emasontweni amabili kuya kwamathathu phakathi nenkathi yokundiza,” kusho uTobin.
Ezimweni zokusetshenziswa okuphoqelekile, izindlela eziphumelela kakhulu zokulawula impukane abaqoqi bothuli, ama-back wipe namathini kawoyela. Kufanele zibekwe ezindaweni lapho imfuyo ingena khona njalo, njengemithombo yamanzi noma izindawo zokudla. Impushana noma uketshezi olusetshenziswa njengesibulala-zinambuzane. UBellew uxwayisa ngokuthi lokhu kudinga ukuhlolwa njalo kwemishini yokugcina izibulala-zinambuzane. Uma izinkomo sezibonile ukuthi ziyazisiza, zizoqala ukuzisebenzisa kaningi, kusho yena.
