Betaineimhando yechinhu chinowedzera chikafu chisina zvinovaka muviri. Chinhu chinogadzirwa kana kubviswa chakavakirwa pamakemikari ari mumhuka dzinonyanya kufarirwa nemhuka dzemumvura. Zvinokwezva chikafu zvinowanzoumbwa nemarudzi anopfuura maviri emakomichi. Makomichi aya ane simba rekubatsirana pakudyisa mhuka dzemumvura. Nekukurudzira kunhuhwirira, kuravira uye kuona kwemhuka dzemumvura, dzinogona kuungana dzakakomberedza chikafu, kukurumidzisa kudya, uye kuwedzera kudya.

Nguva yekudyisa yeMacrobrachium rosenbergii yakapfupikiswa ne 1/3 ~ 1/2 uye huwandu hwekudyisa hwakawedzerwa nekuwedzerabetainechikafu cheshrimp. Kudya kwacho kunebetaineine simba rekukwezva kudya pa carp ne mud carp, asi haina simba rekukwezva kudya pa grass carp. Betaine inogonawo kuwedzera kunaka kwemamwe ma amino acids kuhove uye kuwedzera kukwezva kudya kwe amino acids. Betaine bait ine basa rekuvandudza chishuwo chekudya, kuwedzera kusimba kwezvirwere uye dziviriro yemuviri. Shrimp dzinorwisa chishuwo chemishonga uye dzinotsiva kuderedzwa kwekudya kwehove ne shrimp dzine dambudziko.

Choline chinhu chakakosha mumhuka. Inogona kupa methyl mumuviri mumuviri, nokudaro ichibatanidzwa mukuchinja kwemetabolism. Mumakore achangopfuura, tsvakurudzo yakawana kuti betaine inogonawo kupa methyl mumuviri. Kushanda kwebetaine mukupa methyl kwakapetwa kaviri nehafu kupfuura choline chloride, uye inova methyl donor inoshanda zvikuru. Betaine payakashandiswa kutsiva choline chloride muchikafu, avhareji yehurefu hwemuviri hweMacrobrachium rosenbergii yakawedzera ne27.63% uye chiyero chekudya chakaderera ne8% mushure memazuva 150 zvichienzaniswa neboka rekutonga.Betaineinogona kuvandudza maitiro ekuoxidation kwemafuta acids mumasero mitochondria, kuwedzera zvakanyanya huwandu hwe acyl carnitine yechain refu uye chiyero che acyl carnitine yechain refu kusvika pakusunungura carnitine mutsandanyama nechiropa, kukurudzira kuora kwemafuta, kuderedza kuiswa kwemafuta muchiropa nemuviri, kukurudzira kugadzirwa kwemapuroteni, kugoverazve mafuta ezvitunha, uye kuderedza huwandu hwehuwandu hwemafuta muchiropa.
