Kafukufuku wa makoswe atsimikizira kuti betaine makamaka imagwira ntchito ya methyl donor m'chiwindi ndipo imayendetsedwa ndibetainehomocysteine ​​methyltransferase (BHMT) ndi p-cysteine ​​sulfide β Synthetase (β Regulation of cyst (matope et al., 1965). Chotsatirachi chinatsimikiziridwa mu nkhumba ndi nkhuku. Pamene mankhwala a methyl sakwanira, thupi la nyama limapangitsa kuti hemiaminic acid ivomereze methyl ya betaine mwa kukonza ntchito ya BHMT kupanga methionine ndikupereka methyl. Powonjezera mlingo wochepa wa betaine, chifukwa cha kuchepa kwa methyl m'thupi, chiwindi chimawonjezera nthawi yozungulira ya homocysteine ​​→ methionine mwa kuwonjezera ntchito ya BMT ndi kugwiritsa ntchito betaine monga gawo lapansi, kuti apereke methyl yokwanira pa metabolism yakuthupi. Pa mlingo waukulu, chifukwa exogenous Kuwonjezera kuchuluka kwabetaine, kumbali imodzi, chiwindi chimapereka methyl kwa methyl receptor mwa kukonza ntchito ya BHMT, ndipo kumbali ina, mbali ya homocysteine ​​​​imapanga cysteine ​​sulfide kupyolera mu njira yotumizira sulfure, kuti asunge njira ya methyl metabolism m'thupi lokhazikika lokhazikika. Kuyeseraku kukuwonetsa kuti ndikotetezeka kusintha gawo la methionine muzakudya za bakha a broiler ndi betaine. Betaine imatha kutengeka ndi maselo am'mimba a nkhuku, kuchepetsa kuwonongeka kwa mankhwala ku maselo am'mimba, kusintha mayamwidwe a maselo a m'matumbo a nkhuku, kulimbikitsa kuyamwa kwa michere, ndipo pamapeto pake kumawonjezera magwiridwe antchito komanso kukana matenda a nkhuku.

Betaineimatha kulimbikitsa kutulutsa kwa GH, komwe kumatha kulimbikitsa kaphatikizidwe ka mapuloteni, kuchepetsa kuwonongeka kwa ma amino acid ndikupangitsa kuti thupi likhale loyenera la nayitrogeni. Betaine imatha kuonjezera cyclic adenosine monophosphate mu chiwindi ndi pituitary ( ˆ Zomwe zili mu am, kuti zipititse patsogolo ntchito ya endocrine ya pituitary ndikulimbikitsa kaphatikizidwe ndi kutulutsidwa kwa (h, mahomoni olimbikitsa a chithokomiro) ndi maselo a pituitary α SH ndi mahomoni ena amatha kuonjezera kusungidwa kwa nayitrogeni m'thupi, kuti apititse patsogolo kukula kwa nkhuku. Mayesowa amasonyeza kuti betaine akhoza kuonjezera kwambiri milingo ya seramu h ndi IGF mu nkhumba pazigawo zosiyanasiyana, kulimbikitsa kwambiri kukula kwa nkhumba pazigawo zosiyanasiyana ndikuchepetsa kulemera kwa chakudya. Nkhumba zoletsedwa kuyamwa, nkhumba zokulirapo ndi nkhumba zomaliza zimadyetsedwa ndi zakudya zowonjezeredwa ndi betaine 8001000 ndi 1750ngkg motero, ndipo phindu la tsiku ndi tsiku linawonjezeka ndi 8.71% N13 20% ndi 13.32%, mlingo wa GH wa seramu unawonjezeka ndi 46.15%, 3% ndi 102% motsatira. mlingo wawonjezeka ndi 38.74%, 4.75% ndi 47.95% motsatira (Yu Dongyou et al., 2001). Kuphatikizika kwa betaine m'zakudya kungathenso kupititsa patsogolo kubereka kwa nkhumba, kuonjezera kulemera kwa kubadwa ndi kukula kwa zinyalala za nkhumba, ndipo sikumakhudza kwambiri nkhumba zapakati.

Betaineakhoza kusintha kulolerana kwachilengedwenso maselo kutentha, mkulu mchere ndi mkulu osmotic chilengedwe, bata puloteni ntchito ndi mphamvu kinetic wa kwachilengedwenso macromolecules. Kuthamanga kwa osmotic kwa maselo a minofu kukasintha, betaine imatha kutengeka ndi maselo, kuteteza madzi kutayika ndi kulowa kwa mchere m'maselo, kupititsa patsogolo ntchito ya Na pampu ya maselo, kusunga mphamvu ya osmotic ya maselo a minofu, kuwongolera mphamvu ya osmotic ya maselo, kuchepetsa kupsinjika maganizo ndikuwonjezera kukana matenda.Betaineali ndi mawonekedwe ofanana ndi electrolyte. Pamene m`mimba thirakiti anaukira tizilombo toyambitsa matenda, ali ndi osmotic zoteteza kwambiri maselo a nkhumba m`mimba thirakiti. Ana a nkhumba akataya madzi am'mimba komanso kusalinganika kwa ion chifukwa cha kutsekula m'mimba, betaine imatha kuteteza madzi kutayika ndikupewa hyperkalemia yomwe imayamba chifukwa cha kutsekula m'mimba, kuti tisunge ndikukhazikitsa ma ion bwino am'mimba ndikupanga mabakiteriya opindulitsa muzomera zazing'ono za nkhumba za nkhumba, sizidzateteza mabakiteriya ambiri m'mimba. yachibadwa katulutsidwe wa michere m`mimba thirakiti ndi kukhazikika kwa ntchito yawo, kusintha kukula ndi chitukuko cha m`mimba dongosolo la nkhumba kuyamwa, kusintha digestibility ndi magwiritsidwe mlingo wa chakudya, kuonjezera kudya ndi kulemera tsiku ndi tsiku, kuchepetsa kwambiri kutsegula m'mimba ndi kulimbikitsa kukula mofulumira kwa ana a nkhumba kuyamwa.
