BetaineNdi mtundu wa zowonjezera zosapatsa thanzi, ndizofanana ndi kudya zomera ndi nyama malinga ndi nyama zam'madzi, zomwe zimapangidwa ndi zinthu zopangidwa kapena zotengedwa, zokopa nthawi zambiri zimakhala ndi zinthu ziwiri kapena zingapo, zosakanizazi zimakhala ndi mgwirizano wa kudyetsa nyama zam'madzi, kudzera mu fungo ndi kukoma kwa nyama zam'madzi ndi zokondoweza zowoneka, monga zomwe zimasonkhana mozungulira kudya, kudya komanso kudya.

Kuonjezera betaine ku zakudya za shrimp kungafupikitse 1/3 mpaka 1/2 nthawi yodyetsa ndikuwonjezera kudya kwa macrobrachium rosenbergii. Chakudya chokhala ndi betaine chinali ndi nyambo yowoneka bwino pa carps ndi nyama zakutchire, koma sichinakhudze nyambo pa carps za udzu. Betaine imathanso kukulitsa chidwi cha ma amino acid ena ku nsomba, ndikuwonjezera mphamvu ya ma amino acid. Betaine imatha kukulitsa chikhumbo cha kudya, kukulitsa kukana matenda ndi chitetezo chamthupi, ndikubwezera kuchepa kwa nsomba ndi chakudya cha shrimp pansi pa nkhawa.

Choline ndi gawo lofunikira kwa nyama. Amapereka magulu a methyl m'thupi kuti atenge nawo mbali pazochita za metabolic. M'zaka zaposachedwa, kafukufuku wapeza kuti betaine imathanso kupereka magulu a methyl m'thupi, ndipo mphamvu ya betaine yopereka magulu a methyl ndi 2.3 nthawi ya choline chloride, zomwe zimapangitsa kuti ikhale yothandiza kwambiri ya methyl. Pambuyo pa masiku 150, kutalika kwa thupi la macrobrachium rosenbergii kunawonjezeka ndi 27.63% ndipo chiwerengero cha kusintha kwa chakudya chinachepetsedwa ndi 8% pamene betaine analowa m'malo mwa choline chloride. Betaine imatha kusintha makutidwe ndi okosijeni amafuta acids m'maselo, mitochondria, ndikuwongolera kwambiri minofu ndi chiwindi cha unyolo wautali wa ester acyl carnitine komanso unyolo wautali wa ester acyl carnitine ndi gawo la carnitine yaulere, kulimbikitsa kuwonongeka kwa adipose, kuchepetsa chiwindi ndi kuyika kwamafuta athupi, kulimbikitsa kaphatikizidwe ka mapuloteni, kugawanso mafuta m'thupi.
