Kugwiritsa ntchito Dl-Methionine
{ Feed Grade}
Chakudya cha ziweto cha ziweto chimapangidwa ndi DL-Methionine ndi zinc sulphat.
1. Chifukwa cha momwe mole wa ayoni wa zinki amachitira ndi moles wa methionine, kuchuluka kwa chelate, kukhazikika kwakukulu.
2. High bioavailability, zakudya zabwino za zinki, ndi mtundu wa chakudya chowonjezera chowonjezera.
3. Osakhudzidwa ndi pH mtengo, ma ion ma inorganic ndi ma organic macromolecules m'matumbo am'mimba.
Ntchito ya mankhwala
Onjezani ku zakudya za ziweto, DL-Methionine ingathandize nyama kukula msanga mu nthawi yochepa ndipo pafupifupi 40% ya chakudya chawo akhoza kupulumutsidwa.
1. The bioavailability wa chakudya cha ziweto kwa ziweto bwino kwambiri kuposa organic zinki.
2. Kuthetsa vuto la mng'alu wa ziboda za nkhumba bwino.
3. Wonjezerani kaikire, umuna, ndi kuswa, onjezerani chigoba cha dzira.
4. Zimatsogolera kuchotsedwa kwa nthenga zonyansa ndi zowonongeka, kupeza nthenga yowala.Ndipo kuchepa kwa cannib alism ya kujowola mapiko ndi anus.
5. Kuchulukitsa kudya moyenera, kumatha kukulitsa kukula kwa ziweto komanso kukana matenda, kulimbikitsa zakudya zambiri.
6. Zinc methionine iyi ikhoza kuwonjezera pa zakudya zopanda thanzi, zomwe zimapangitsa kuti ziweto zikule.
{Food Grade}
DL-Methionine ndi amodzi mwa 18 amino zidulo wamba, ndi imodzi mwa zisanu ndi zitatu zofunika amino zidulo pa nyama ndi thupi la munthu.Amagwiritsidwa ntchito ngati zowonjezera zakudya muzakudya za nsomba, nkhuku, nkhumba ndi ng'ombe kuti nyama ndi mbalame zizikula bwino.Ikhoza kusintha katulutsidwe ka mkaka wa ng'ombe, kupewa kupezeka kwa hepatosis.Komanso, angagwiritsidwe ntchito ngati amino acid mankhwala, jekeseni njira, ndi zakudya kulowetsedwa, wothandizila zoteteza chiwindi, mankhwala chiwindi matenda enaake ndi poizoni chiwindi.
1. DL-Methionine ingagwiritsidwe ntchito popanga mavitamini a mankhwala, zakudya zowonjezera zakudya komanso zowonjezera zakudya.
2. DL-Methionine ndi chimodzi mwa zigawo zikuluzikulu za kulowetsedwa kwa amino acid ndi amino acid pawiri.DL-Methionine ali ndi ntchito yotsutsa-mafuta chiwindi.Pogwiritsa ntchito ntchitoyi, mavitamini opangira mankhwala angagwiritsidwe ntchito ngati mankhwala otetezera chiwindi.
3. Monga amino acid ofunikira m'thupi la munthu, DL-Methionine ikhoza kugwiritsidwa ntchito ngati chakudya chowonjezera pazakudya ndi kukonza zosungirako monga mankhwala a keke ya nsomba.
4. Monga gawo lofunika kwambiri pakupanga mapuloteni, DL-Methionine imakhala ndi chitetezo pa minofu ya mtima.Pa nthawi yomweyi, DL-Methionine ikhoza kusinthidwa kukhala Taurine ndi sulfure, pamene Taurine ili ndi zotsatira zoonekeratu za hypotensive.DL-Methionine imakhalanso ndi ntchito yabwino yoteteza chiwindi ndi kuchotseratu poizoni, choncho imagwiritsidwa ntchito kwambiri pochiza matenda a chiwindi monga matenda a chiwindi, mafuta a chiwindi ndi matenda osiyanasiyana opweteka komanso aakulu.Zimakhala ndi zotsatira zabwino kwambiri.
5. DL-Methionine angagwiritsidwe ntchito ngati nutional zowonjezera.DL-Methionine imakhala ndi zotsatira zofanana ndi L-Methionine, koma DL-Methionine ndiyotsika mtengo.
6. DL-Methionine ikhoza kupangidwa ngati chokometsera.
7. DL-Methionine ndiye chowonjezera cha zakudya.Ziweto ndi nkhuku kusowa kwa Methionine, kungayambitse kukula kwapang'onopang'ono, kuchepa kwa thupi, kuchepa kwa chiwindi ndi impso, minofu atrophy, ubweya, metamorphism ndi zina zotero.Onjezani 1 kg methionine, chakudya cha 50 kg chakudya cha nsomba.Dyetsani zomwe zili mu 0.05% mpaka 0.2%.
