Nguva yekudya yeMacrobrachium rosenbergii yakapfupikiswa ne1/3 ~ 1/2 uye huwandu hwekudya hwakawedzerwa nekuwedzera.betainekune shrimp feed.Chikafu chinebetaineine mhedziso yekudyisa inokwezva pacarp uye mudhaka carp, asi haina mhedziso yekudyisa inokwezva pauswa carp.Betaine inogona zvakare kuwedzera kuravira kweimwe amino acids kuhove uye kuwedzera kukwezva kwekudya kweamino acids.Betaine bait ine mabasa ekuvandudza kudya, kuwedzera kudzivirira kwechirwere uye kusadzivirirwa.Chirwere shrimp chinodzivisa chirauro chemushonga uye kutsiva kuderedzwa kwekudya kwehove uye shrimp mukushushikana.

Choline chinhu chakakosha chekudya mumhuka.Iyo inogona kupa methyl yemuviri mu vivo, nekudaro kutora chikamu mune metabolic maitiro.Mumakore achangopfuura, tsvagiridzo yakawana kuti betaine inogona zvakare kupa methyl kumuviri.Kushanda kwebetaine mukupa methyl ndeye 2.3 nguva yecholine chloride, uye inoshanda zvakanyanya methyl donor.Pakashandiswa betaine kutsiva choline chloride muchikafu, avhareji urefu hwemuviri weMacrobrachium rosenbergii hwakawedzera ne27.63% uye chekudya chakadzikira ne8% mushure memazuva zana nemakumi mashanu zvichienzaniswa neboka rekutonga.Betaineinogona kuvandudza oxidation process ye fatty acids musero mitochondria, zvakanyanya kuwedzera zviri mukati-refu-chain acyl carnitine uye chiyero chenguva refu-chain acyl carnitine kumahara carnitine mumhasuru uye chiropa, kukurudzira kuparara kwemafuta, kuderedza kuiswa kwemafuta muchiropa uye mumuviri. , kusimudzira mapuroteni synthesis, kugoverazve mafuta echitunha, uye kuderedza chiitiko chechiropa chemafuta.
