Kuyesedwa kwabwino kwa mkaka kumathandizira kuti zinthu za mkaka zikhale zokhazikika

Urea, chigawo chomwe chili m'magazi, mkodzo ndi mkaka, ndiye njira yayikulu yochotsera nayitrogeni mu nyama zoyamwitsa.Kuzindikira kuchuluka kwa urea mu ng'ombe za mkaka kumathandiza asayansi ndi alimi kumvetsetsa momwe nitrogen mu chakudya amagwiritsidwira ntchito bwino mu ng'ombe za mkaka.Ndikofunikira kwa alimi potengera mtengo wa chakudya, momwe ng ombe za mkaka zimakhudzira thupi (monga kubereka), komanso kukhudzidwa kwa chimbudzi pa chilengedwe.Kufunika kwachuma kwa nayitrogeni mu manyowa a ng'ombe.Chifukwa chake, ndikofunikira kudziwa kuchuluka kwa urea mu ng'ombe za mkaka.Kuyambira zaka za m'ma 1990, kuzindikira kwapakati pa infrared kwa milk urea nitrogen (MUN) kwakhala njira yothandiza kwambiri komanso yocheperako yomwe imagwiritsidwa ntchito poyeza nayitrogeni mu ng'ombe zambiri zamkaka.M'nkhani yaposachedwa yomwe idasindikizidwa mu Journal of Dairy Science, ofufuza a ku Cornell University adanenanso za kukhazikitsidwa kwa magulu atsopano a MUN calibration zitsanzo kuti apititse patsogolo kulondola kwa miyeso ya MUN.
"Pamene gulu la zitsanzozi likuyendetsedwa pa makina osanthula mkaka, deta ingagwiritsidwe ntchito kuti azindikire zolakwika zinazake mu khalidwe lolosera la MUN, ndipo wogwiritsa ntchito chipangizocho kapena wopanga mkaka wa analyzer akhoza kukonza zolakwika izi," adatero mkulu. wolemba David.Dr. M. Barbano, Northeast Dairy Research Center, Dipatimenti ya Food Science, University of Cornell, Ithaca, New York, USA.Zambiri zolondola komanso zapanthawi yake za MUN "ndizofunika kwambiri pakuweta ng'ombe za mkaka ndi kasamalidwe ka ng'ombe za mkaka," anawonjezera Barbano.
Chifukwa cha kuchuluka kwapadziko lonse lapansi pakuwunika momwe chilengedwe chimakhudzira ulimi waukulu komanso zovuta zachuma zomwe alimi amakumana nazo, kufunikira komvetsetsa bwino ntchito ya nayitrogeni mumakampani a mkaka sikungakhale kofulumira kwambiri.Kuwongolera kumeneku pakuyesa kuchuluka kwa mkaka kukuwonetsa kupita patsogolo kwaulimi komanso njira zopangira zakudya zomwe zingathandize opanga komanso ogula.Onani Portnoy M et al.Infrared milk analyzer: mkaka urea nitrogen calibration.J.
