Tlhaloso ea Sehlahisoa:Selenium ke liminerale tsa bohlokoa bakeng sa kholo le nts'etsopele ea liphoofolo, ka katleho e fokotsa khatello ea oxidative. Selenium e eketsoa ho fepa ka litekanyo tse tlase haholo (ka tlase ho 1mg/kg ka tone ea phepelo), e hlokang botle bo phahameng haholo le ho tsoakoa ho tšoanang ha motsoako o sebetsang. Chengdu Shuxing Feed, ho nahanela litšobotsi tsa selenium, e hlahisitse sehlahisoa sa selenium se nang le lerole le tlaase, se se nang chefo, le se se nang chefo ho thusa liphoofolo ka katleho ho tlatsetsa selenium le ho ntlafatsa bophelo ba tsona.

Lintlha tsa tekheniki ea sehlahisoa:
v Thepa e tala ke lisebelisoa tsa boleng bo holimo tsa selenium tse tsoang kantle ho naha, 'me litaba tsa metale tse boima joalo ka arsenic, lead, chromium le mercury li tlase haholo ho feta maemo a naha. E bolokehile, ha e na tikoloho ebile ha e na chefo.
v Thepa e tala ea sodium selenite e hatelloa ke lisebelisoa tsa ho roala li-ultra-fine, 'me boholo ba karoloana bo ka fihla ho 400-600 mesh, e leng ho ntlafatsang haholo ho solubility le bioavailability.
v Re sebelisa li-diluent le lijari tse ntlafalitsoeng ke k'hamphani ea rona ho netefatsa hore sehlahisoa se na le metsi le ho ts'oana ka ho hlapolla ha gradient le ho kopanya hangata. Mokelikeli o babatsehang o tiisa kabo e tšoanang ka har'a fepa.

Melemo ea Sehlahisoa :
Selenium, e le karolo ea glutathione peroxidase, e ntlafatsa matla a antioxidant a liphoofolo.
v E ka laola tlhahiso ea lihomone tsa pelehi le ho ntlafatsa ts'ebetso ea pelehi
v Khothalletsa ho kopanya liprotheine tsa mesifa le ho khothaletsa kholo ea liphoofolo
v Ntlafatsa sesole sa 'mele le ho matlafatsa boipelaetso ba mafu
Ntlafatsa tlhahiso ea selenium, hlahisa lihlahisoa tse nang le selenium e ngata, le ho eketsa boleng ba sehlahisoa
Lisebelisoa tsa liphoofolo:

Enterotoxigenic Escherichia coli (ETEC) e ka baka letšollo ho likolobe. Boithuto bo bontšitse hore ho kenyelletsa selenium lijong tsa likolobe ho fokotsa lipopolysaccharide synthesis ho ileal microbiome, ho fokotsa index ea letšollo le lets'ollo ho likolobe.
2) likhoho tse behelang
Ho kenyelletsa sodium selenite lijong tsa likhoho tse behelang ho ka ntlafatsa ts'ebetso ea kholo ea likhoho tse behelang, ho lelefatsa bophelo ba lishelefo le selenium maheng, le ho eketsa boleng ba phepo ea mahe.
3) li-ruminants
Ho eketsa selenium ho linku tsa Hu ho ke ke ha eketsa selenium feela liseleng le ho hlahisa mutton e nang le selenium e ngata; e ka boela ea eketsa matla a antioxidant ea serum, ea fokotsa boemo ba malondialdehyde, le ho ntlafatsa bokhoni ba ho hanela khatello ea kelello.
