1. Antioxidant basa: Selenium ndiyo inoshandiswa pakati peGPx, uye iyo antioxidant function inowanikwa kuburikidza neGPx uye thioredoxin reductase (TrxR). Antioxidant basa ndiro basa guru re selenium, uye mamwe mabasa ehupenyu anonyanya kuenderana neizvi.
2. Kukurudzira Kukura: Nhamba huru yezvidzidzo zvakaratidza kuti kuwedzera organic selenium kana inorganic selenium mukudya kunogona kuvandudza kushanda kwehuku, nguruve, ruminants kana hove, sekuderedza chiyero chekudya kune nyama uye kuwedzera uremu hwezuva nezuva. gain.
3. Kuvandudzwa kwekuita kubereka: Zvidzidzo zvakaratidza kuti selenium inogona kuvandudza kufamba kwembeu uye kuwedzera kwembeu mumbeu, nepo kushaikwa kwe selenium kunogona kuwedzera kukanganiswa kwembeu;Kuwedzera selenium mukudya kunogona kuwedzera fetiraiza yembeu, kuwedzera huwandu hwemarara, kuwedzera. chiyero chekugadzirwa kwezai, kunatsiridza ganda remazai uye kuwedzera uremu hwezai.
4. Kuvandudza hutano hwenyama: Lipid oxidation ndiyo chinhu chikuru chekuora kwehutano hwenyama, selenium antioxidant basa ndicho chinhu chikuru chekuvandudza nyama.
5. Kubvisa huturu: Zvidzidzo zvakaratidza kuti selenium inogona kupikisa uye kuderedza huturu hwemutobvu, cadmium, arsenic, mercury nezvimwe zvinokuvadza, fluoride uye aflatoxin.
6. Mamwe mabasa: Mukuwedzera, selenium inoita basa rinokosha mukudzivirira, selenium deposition, hormone secretion, digestive enzyme basa, nezvimwewo.
Maitiro ekushandisa anonyanya kuratidzwa mune zvinotevera zvinhu zvina:
1.Kugadzirwa kwekuita (zuva nezuva kuwedzera uremu, kushanduka kwemafuro uye zvimwe zviratidzo).
2.Reproductive performance (sperm motility, conception rate, live litter size, birth weight, etc.).
3.Meat, zai uye mukaka quality (nyama quality - kudonha kurasikirwa, nyama ruvara, zai uremu uye selenium deposition munyama, zai uye mukaka).
4.Blood biochemical indexes (ropa selenium level uye gsh-px basa).
