Betaine, tseem hu ua glycine trimethyl sab hauv ntsev, yog ib qho tsis muaj tshuaj lom thiab tsis muaj teeb meem ntuj tsim, quaternary amine alkaloid.Nws yog dawb prismatic los yog nplooj zoo li siv lead ua nrog molecular mis C5H12NO2, molecular hnyav ntawm 118 thiab melting point ntawm 293 ℃.Nws qab qab zib thiab yog ib qho tshiab uas tsis yog tshuaj tua kab mob pub mis ntxiv.

Nws tau pom tias betaine tuaj yeem nce tus naj npawb thiab qhov hnyav ntawm 21 hnub qub weaned piglets, ua kom lub sijhawm estrous tsis pub dhau 7 hnub tom qab tau txiav thiab txhim kho kev ua me nyuam;Nws tseem tuaj yeem txhawb nqa ovulation thiab oocyte maturation;Raws li methyl pub dawb, betaine tuaj yeem txhawb kev tsim cov protein thiab txo qis homocysteine ​​​​hauv cov ntshav qab zib, txhawm rau txhawb kev loj hlob ntawm embryo thiab kev loj hlob thiab txhim kho cov noob qoob loo.

Cov teebmeem ob ntawm betaine tuaj yeem txhim kho kev tsim khoomkev ua tau zoo ntawm cov tsiajnyob rau hauv tag nrho cov theem ntawm cev xeeb tub, cev xeeb tub, lactation thiab fattening.Thaum lub sij hawm weaning, lub cev qhuav dej ntawm piglets tshwm sim los ntawm physiological kev nyuaj siab yog ib qho nyuaj rau cov neeg tsim npua.Raws li osmotic regulator, ntuj betaine tuaj yeem txhim kho cov dej tuav thiab nqus thiab txo lub zog noj los ntawm kev tswj hwm qhov sib npaug ntawm dej thiab ions hauv hlwb.Lub caij ntuj sov kub yuav ua rau poob qis hauv kev muaj peev xwm ntawm cov noob qoob loo.Raws li kev tswj hwm osmotic, betaine tuaj yeem txhim kho lub zog ntawm cov noob qoob loo thiab txhim kho kev muaj peev xwm ntawm cov noob qoob loo.Ntxiv cov betaine ntuj rau pub tuaj yeem txhim kho txoj hnyuv ntawm cov tsiaj, thaum muaj teeb meem xws li kev ntxhov siab kub yuav ua rau cov plab hnyuv elasticity tsis zoo.Thaum lub ambient kub nce, cov ntshav yuav nyiam ntws mus rau ntawm daim tawv nqaij kom sov dissipation.Qhov no ua rau txo cov ntshav khiav mus rau lub plab zom mov, uas ua rau muaj kev cuam tshuam rau kev zom zaub mov thiab txo cov digestibility ntawm cov as-ham.

 

Kev koom tes ntawm betaine rau methylation tuaj yeem txhim kho tsiaj cov txiaj ntsig zoo.Kev ntxiv ntawm betaine nyob rau hauv sow pub yuav txo tau cev xeeb tub poob, txhim kho sow kev yug me nyuam kev ua tau zoo thiab nce litter loj ntawm tom ntej parity.Betaine tseem tuaj yeem txuag lub zog rau cov npua ntawm txhua lub hnub nyoog, yog li siv lub zog metabolic ntau ntxiv los ua kom cov nqaij ntshiv nqaij thiab txhim kho tsiaj muaj zog.Cov nyhuv no yog qhov tseem ceeb thaum lub sij hawm weaning hauv piglets uas xav tau ntau zog los tswj.
