1. Antioxidant muaj nuj nqi: Selenium yog lub active centre ntawm GPx, thiab nws cov antioxidant muaj nuj nqi yog paub los ntawm GPx thiab thioredoxin reductase (TrxR). Antioxidant muaj nuj nqi yog lub luag haujlwm tseem ceeb ntawm selenium, thiab lwm yam kev ua haujlwm lom neeg feem ntau yog raws li qhov no.
2. Kev txhawb nqa kev loj hlob: Muaj ntau cov kev tshawb fawb tau ua pov thawj tias ntxiv cov organic selenium los yog inorganic selenium rau cov khoom noj tuaj yeem txhim kho kev loj hlob ntawm cov nqaij qaib, npua, ruminants los yog ntses, xws li txo qhov piv ntawm pub rau nqaij thiab nce qhov hnyav txhua hnub. nce.
3. Txhim kho kev ua me nyuam: Cov kev tshawb fawb tau pom tias selenium tuaj yeem txhim kho cov phev motility thiab cov phev suav hauv cov phev, thaum selenium deficiency tuaj yeem ua rau cov phev malformation tus nqi; Ntxiv selenium hauv kev noj zaub mov tuaj yeem ua rau cov fertilizing tus nqi ntawm sows, nce cov litter, nce. tus nqi ntawm qe ntau lawm, txhim kho qe zoo thiab ua kom lub qe hnyav.
4. Txhim kho nqaij zoo: Lipid oxidation yog qhov tseem ceeb ntawm cov nqaij zoo deterioration, selenium antioxidant muaj nuj nqi yog lub ntsiab tseem ceeb los txhim kho nqaij zoo.
5. Detoxification: Cov kev tshawb fawb tau pom tias selenium tuaj yeem tiv thaiv thiab txo cov tshuaj lom ntawm cov hlau lead, cadmium, arsenic, mercury thiab lwm yam teeb meem, fluoride thiab aflatoxin.
6. Lwm cov haujlwm: Tsis tas li ntawd, selenium plays lub luag haujlwm tseem ceeb hauv kev tiv thaiv kab mob, selenium deposition, hormone secretion, digestive enzyme kev ua, thiab lwm yam.
Cov txiaj ntsig ntawm daim ntawv thov feem ntau yog tshwm sim hauv plaub yam hauv qab no:
1.Production kev ua tau zoo (txhua hnub hnyav nce, pub conversion efficiency thiab lwm yam ntsuas).
2.Reproductive performance ( phev motility, conception rate, live litter size, birth weight, etc.).
3.Nqaij, qe thiab mis nyuj zoo (nqaij zoo - poob poob, nqaij xim, qe hnyav thiab selenium deposition hauv nqaij, qe thiab mis nyuj).
4.Blood biochemical indexes (cov ntshav selenium qib thiab gsh-px kev ua haujlwm).
