Betainendi mtundu wa non nutritive zowonjezera.Ndi chinthu chopangidwa mwachisawawa kapena chotengedwa motengera zinthu zomwe zili mu nyama zomwe zimakonda kwambiri komanso zomera za nyama zam'madzi.Zokopa zakudya nthawi zambiri zimakhala ndi mitundu yambiri yamitundu iwiri.Mankhwalawa ali ndi mphamvu ya synergistic pa kudyetsa nyama zam'madzi.Polimbikitsa fungo, kukoma ndi masomphenya a nyama za m'madzi, zimatha kusonkhana mozungulira chakudya, kufulumizitsa kudyetsa, ndi kuonjezera kudya.

Nthawi yodyetsera ya Macrobrachium rosenbergii idafupikitsidwa ndi 1/3 ~ 1/2 ndipo kuchuluka kwa chakudya kumawonjezeka powonjezera.betaineku chakudya cha shrimp.The zakudya munalibetaineali ndi zodziwikiratu kudyetsa kukopeka pa carp ndi matope carp, koma alibe zoonekeratu kudya kukopa zotsatira pa udzu carp.Betaine imathanso kukulitsa kawonedwe ka ma amino acid ena osodza ndikuwonjezera kukopa kwa ma amino acid.Nyambo ya Betaine ili ndi ntchito yopititsa patsogolo chilakolako cha chakudya, kulimbikitsa kukana matenda komanso chitetezo chamthupi.Nsomba za matenda zimakana nyambo yamankhwala ndikubwezera kuchepa kwa chakudya cha nsomba ndi shrimp pansi pa nkhawa.

Choline ndi gawo lofunikira lazakudya zanyama.Ikhoza kupereka methyl kwa thupi mu vivo, motero kutenga nawo mbali pazochitika za metabolic.M'zaka zaposachedwa, kafukufuku wapeza kuti betaine imatha kuperekanso methyl m'thupi.Kuchita bwino kwa betaine popereka methyl ndi nthawi 2.3 kuposa choline chloride, ndipo ndi wothandizira kwambiri wa methyl.Betaine atagwiritsidwa ntchito m'malo mwa choline chloride m'zakudya, pafupifupi kutalika kwa thupi la Macrobrachium rosenbergii kudakwera ndi 27.63% ndipo kuchuluka kwa chakudya kumatsika ndi 8% patatha masiku 150 poyerekeza ndi gulu lolamulira.Betaineimatha kupititsa patsogolo kayendedwe ka makutidwe ndi okosijeni mu cell mitochondria, kukulitsa kwambiri zomwe zili mu unyolo wautali wa acyl carnitine ndi chiŵerengero cha unyolo wautali wa acyl carnitine ku free carnitine mu minofu ndi chiwindi, kulimbikitsa kuwonongeka kwamafuta, kuchepetsa mafuta m'chiwindi ndi thupi. , kulimbikitsa kaphatikizidwe ka mapuloteni, kugawanso mafuta a nyama, komanso kuchepetsa kuchuluka kwa chiwindi chamafuta.
