Kuita kwakasiyana-siyana kwekushushikana kunokanganisa zvakanyanya kudya nekukura kwemhuka dzemumvura, kuderedza huwandu hwekupona, uye kutokonzera rufu.Kuwedzera kwebetainemukudya kunogona kubatsira kuvandudza kudzikira kwekudya kwemhuka dzemumvura pasi pehosha kana kushushikana, kuchengetedza kudya kunovaka muviri uye kuderedza mamwe mamiriro echirwere kana kusagadzikana.

Betaineinogona kubatsira salmon kudzivirira kutonhora kuri pasi pe10 ℃, uye chinhu chakanakira chikafu chekuwedzera kune dzimwe hove munguva yechando.Mbeu dzehuswa dzecarp dzakatakurwa kureba dzakaiswa mumadziva A neB nemamiriro akafanana.0.3% betaine yakawedzerwa kune uswa carp feed mupond a, uye betaine haina kuwedzerwa kune uswa carp chikafu mudziva B. Migumisiro yakaratidza kuti uswa carp mbesa mudziva a yaishanda mumvura, yakadya nokukurumidza, uye yakaita. kwete kufa;Fry mudziva B yaidya zvishoma nezvishoma uye kufa kwaive 4.5%, zvichiratidza kuti betaine ine anti stress effect.

Betainechinhu chinodzivirira cheosmotic stress.Inogona kushandiswa se osmotic inodzivirira mumiriri wemasero.Inogona kuvandudza kushivirira kwemasero ezvisikwa kusvika pakusanaya kwemvura, humidity yakakwira, munyu wakawanda uye hypertonic nharaunda, kudzivirira kurasikirwa kwesero mvura uye kupinda munyu, kuvandudza basa reNa-K pombi ye cell membrane, kudzikamisa enzyme basa uye biological macromolecular basa, kuitira kudzora matishu uye sero osmotic pressure uye ion balance, Chengetedza kunyudzwa kwechikafu, kuwedzera kushivirira kwehove uye shrimp kana osmotic pressure ichichinja zvakanyanya, uye kuvandudza chiyero chekutaura.

Kuwanda kwemunyu mumvura yegungwa kwakakwira zvakanyanya, izvo zvisingakodzeri kukura uye kurarama kwehove.Kuedza kwecarp kunoratidza kuti kuwedzera 1.5% betaine / amino acid kune chirauro kunogona kuderedza mvura mumhasuru yehove dzemvura yakachena uye kunonoka kuchembera kwehove dzemvura yakachena.Kana huwandu hwemunyu mumvura huchiwedzera (semvura yegungwa), zvinobatsira kuchengetedza electrolyte uye osmotic pressure balance yehove dzemvura yakachena uye kuita shanduko kubva kuhove dzemvura yakachena kuenda kunharaunda yemvura yegungwa zvakanaka.Betaine inobatsira zvipenyu zvemugungwa kuchengetedza munyu wakaderera mumiviri yavo, ichiramba ichizadza mvura, ichiita basa mukutonga kweosmotic, uye kugonesa hove dzemvura yakachena kuti dzienderane neshanduko kunharaunda yemvura yegungwa.
