RALEIGH, NC — Ukukhiqizwa kwezinkukhu kusalokhu kuyimbangela eyinhloko embonini yezolimo yesifundazwe,kodwa inkathazo isongela lo mkhakha obalulekile.
I-North Carolina Poultry Federation ithi iyimpahla enkulu kunazo zonke esifundazweni, inikela cishe amaRandi ayizigidigidi ezingama-40 minyaka yonke emnothweni wesifundazwe.
Kodwa-ke, izinambuzane ziyingozi kule mboni ebalulekile, okuphoqa abalimi ukuthi basebenzise izindlela zokulawula izinambuzane ngamakhemikhali, ezingathinta impilo yabantu.
Manje ukuxhaswa ngezimali kuzwelonke kudlala indima ebalulekile ocwaningweni olusha oluthembisa ukuthola izixazululo ezingcono.
Izitsha zepulasitiki eFayetteville State University ziyikhaya lezinambuzane ezincane eziphazamisa imboni engenisa izigidigidi zamaRandi.
Abacwaningi bafunda ngamaqoqo ezinkumbi zamaqabunga amnyama ukuze baqonde kangcono izinambuzane ezibeka ingcindezi embonini yezinkukhu.
Lezi zinambuzane zikhangwa ukudla kwezinkukhu futhi zizalana ngokushesha, zibeka amaqanda kulo lonke ihhoko, bese zichanyuselwa zibe izibungu.
Phakathi nezinyanga eziningana, ziyaguquka zibe yizimpukane bese zikhula zibe yizimpukane ezindala ezinamathela ezinyonini.
"Bavame ukuthola izinkukhu, bese izimbungulu zinamathela kuzo. Yebo, zidla izinkukhu," kusho uShirley Zhao, uprofesa webhayoloji eFayetteville State University.
UZhao waphawula ukuthi izinyoni zingase zizibheke njengesidlo sokudla okulula, kodwa ukudla lezi zinambuzane eziningi kakhulu kungabangela enye inkinga.
“Kukhona indawo ebizwa ngokuthi isivuno, uhlobo lwesisu, lapho kugcinwa khona ukudla,” kusho yena. “Kunezinambuzane eziningi kakhulu lapho kangangokuthi azinazo izakhamzimba ezanele.”
Abalimi baqala ukusebenzisa izibulala-zinambuzane ukubulala izinambuzane, kodwa zazingasetshenziswa eduze kwezinyoni, okwanciphisa ikhono labalimi lokulawula izinambuzane.
"Ukuchayeka kula makhemikhali nakwamanye kungaba nemiphumela ebalulekile empilweni yethu," kusho uKendall Wimberly, umphathi wenqubomgomo ye-Drug-Free North Carolina.
UWimberly uthe umonakalo obangelwa yilezi zibulala-zinambuzane udlulela ngale kwezindonga zezinkukhu, njengoba amanzi ageleza kula mapulazi ephelela emifuleni nasemifudlaneni yethu.
“Izinto ezisetshenziswa ezindlini zezinkukhu noma ngisho nasemakhaya ngezinye izikhathi zigcina zisezindleleni zethu zamanzi,” kusho uWimberly. “Uma ziqhubeka endaweni ezungezile, zidala izinkinga zangempela.”
"Bahlasela uhlelo lwezinzwa, ngakho-ke bahlasela lokho ngqo," kusho uChao. "Inkinga ukuthi uhlelo lwezinzwa lwesinambuzane empeleni lufana kakhulu nolwethu."
"Babedinga ukuthola indlela yokwandisa inani lezinambuzane ababezinakekela," kusho uZhao. "(Omunye umfundi) wayefuna ukubanika insangu. Ezinyangeni ezimbalwa kamuva, sathola ukuthi zonke zazifile. Zazingakaze zikhule."
UChao uthole isibonelelo se-NCInnovation esingu-$1.1 million esigabeni esilandelayo socwaningo lwakhe: ucwaningo lwasensimini.
Usevele exoxisane nezinkampani ezifana noTyson noPerdue, eziveze intshisekelo yokusebenzisa umuthi wokubulala izinambuzane uma usebenza kahle futhi uvunyelwe yi-Environmental Protection Agency. Uthi le nqubo ngabe ingenzeki ngaphandle kokutshalwa kwezimali kukahulumeni ocwaningweni lwakhe.
“Angazi ukuthi zingaki izinkampani ezincane ezingavuma ukusebenzisa u-$10 million ukubhalisa umuthi wokubulala izinambuzane,” kusho yena.
Nakuba kungase kuthathe iminyaka eminingana ngaphambi kokuba ifike emakethe, uWimberly uthe kuyintuthuko ekhuthazayo.
“Sithemba ukubona ezinye izindlela eziphephile kakhulu kunezibulala-zinambuzane ezivame ukuba nobuthi,” kusho uWimberly.
UZhao nethimba lakhe balungiselela ukwakha isibaya sezinkukhu kanye nendlu yokupheka izinkukhu emaphandleni aseNorth Carolina ukuze baqale ukuhlola ifomula yabo yokubulala izinambuzane ensimini.
Uma lezi zivivinyo ziphumelela, ifomula kumele ihlolwe ubuthi ngaphambi kokuba ibhaliswe ne-EPA.
