Qhov kev loj hlob qeeb ntawm piglets tom qab weaning yog vim muaj kev txwv ntawm kev zom thiab nqus tau, tsis txaus ntawm hydrochloric acid thiab trypsin, thiab tam sim ntawd hloov cov concentration ntawm pub thiab pub noj.Cov teeb meem no tuaj yeem kov yeej los ntawm kev txo cov pH noj zaub mov nrog cov organic acids tsis muaj zog.Lub luag haujlwm tseem ceeb ntawm cov organic acids yog cuam tshuam nrog kev txo qis ntawm pH ntawm plab, uas hloov cov pepsinogen tsis ua haujlwm rau hauv pepsin nquag.Organic acids tuaj yeem tiv thaiv kab mob thiab tua kab mob.Organic acids tuaj yeem txo qis excretion ntawm cov minerals ntxiv thiab nitrogen, vim lawv tsim complexes nrog minerals, uas pab txhim kho lawv bioavailability.Organic acids kuj tuaj yeem txhim kho qhov pom tseeb tag nrho cov plab zom mov digestibility thiab kev loj hlob.Nyob rau hauv ib lo lus, organic acids thiab lawv cov ntsev txhim kho cov protein siv tus nqi thiab ntau lawm Performance index ntawm weaned piglets.
Calcium propionate tuaj yeem tsis tsuas yog txhim kho kev ua haujlwm ntawm pepsin, tab sis kuj txhim kho kev siv cov protein, uas muaj txiaj ntsig zoo rau ib puag ncig thiab kev lag luam tsim khoom.Tus nqi pH qis kuj tseem tuaj yeem txhim kho qhov digestibility ntawm cov as-ham los ntawm kev hloov cov villus qhov siab thiab crypt qhov tob ntawm cov hnyuv me.Qhov tshwm sim no tuaj yeem piav qhia los ntawm qhov tseeb tias cov protein hauv cov mis nyuj (casein) yuav tsum muaj pH tus nqi ntawm 4 hauv npua lub plab thiaj li ua kom coagulate, precipitate thiab ua tiav qhov siab tshaj plaws ntawm kev zom zaub mov ntawm 98%.
Organic acids kuj tseem suav hais tias yog cov tshuaj tiv thaiv zoo, uas tuaj yeem tiv thaiv cov khoom noj los ntawm kev loj hlob ntawm cov kab mob phem lossis cov fungi.Nyob rau tib lub sijhawm, kev txhim kho kev noj zaub mov zoo tuaj yeem pab txhim kho kev loj hlob.Lub luag haujlwm tseem ceeb ntawm acidifier khaws cia cov khoom xyaw yog txo qis pH tus nqi ntawm cov khoom noj.
Organic acids tsis tsuas yog inhibit cov kab mob, tab sis kuj tua cov kab mob.Cov teebmeem no nyob ntawm lawv cov ntsiab lus.Cov kua qaub no tuaj yeem siv tau zoo nrog lwm cov khoom noj ntxiv.
