I-Urea, i-compound ekhoyo egazini, kumchamo nasebisini, yeyona ndlela iphambili yokukhutshelwa kwenitrogen kwizilwanyana ezanyisayo.Ukubona izinga le urea kwiinkomo zobisi kunceda oosonzululwazi kunye namafama aqonde indlela initrogen ekutyeni esetyenziswa ngayo kakuhle kwiinkomo zobisi.Kubalulekile kumafama ngokweendleko zesondlo, ifuthe lomzimba kwiinkomo zobisi (ezifana nokuzala), kunye nefuthe lokukhutshelwa kokusingqongileyo.Ukubaluleka kwezoqoqosho kwenitrogen kumgquba wenkomo.Ngoko ke, ukuchaneka kokuchongwa kwamanqanaba e-urea kwiinkomo zobisi kubalulekile.Ukusukela ngeminyaka yoo-1990s, ukubonwa kwe-milk urea nitrogen (MUN) ibiyeyona ndlela isebenzayo nencinci esetyenziswayo ukulinganisa initrogen kwizixa ezikhulu zeenkomo zobisi.Kwinqaku lamva nje elipapashwe kwiJournal of Dairy Science, abaphandi kwiYunivesithi yaseCornell banike ingxelo malunga nokuphuhliswa kweseti enamandla yeesampulu zereferensi yokulinganisa i-MUN ukuphucula ukuchaneka kwemilinganiselo ye-MUN.
"Xa iseti yezi sampuli ziqhutyelwa kwi-analyzer yobisi, idatha ingasetyenziselwa ukufumanisa iziphene ezithile kumgangatho wokuxela kwangaphambili kwe-MUN, kwaye umsebenzisi wesixhobo okanye umenzi we-analyzer yobisi unokulungisa ezi ziphene," kuchaza umdala. umbhali uDavide.UGqr M. Barbano, iZiko loPhando lweDairy yaseNyakatho-mpuma, iSebe leSayensi yoKutya, iYunivesithi yaseCornell, i-Ithaca, eNew York, eU.SA.Ulwazi oluchanekileyo kunye nolusexesheni lwe-MUN yoxinaniso "lubaluleke kakhulu ekondleni umhlambi wobisi kunye nokulawula ukuzala," wongezelela uBarbano.
Ngenxa yokunyuka kokuphononongwa kwehlabathi jikelele malunga nempembelelo yokusingqongileyo yezolimo ezinkulu kunye nemingeni yezoqoqosho ejongene namafama, imfuno yokuqonda ngokuchanekileyo ukusetyenziswa kwe-nitrogen kumashishini obisi ayinakuze ibe yinto engxamisekileyo.Olu phuculo lovavanyo lokwakheka kobisi luphawula inkqubela phambili ekhokelela kwiindlela ezinempilo nezizinzileyo kwezolimo kunye nemveliso yokutya, okuya kuthi kuxhamle abavelisi kunye nabathengi.Bona Portnoy M et al.I-infrared milk analyzer: ubisi lwe-urea nitrogen calibration.J.
