Lub luag haujlwm tseem ceeb ntawm Acidifier hauv kev pub noj yog txo qis pH tus nqi thiab cov kua qaub khi lub peev xwm ntawm pub.Qhov sib ntxiv ntawm acidifier rau cov khoom noj yuav txo cov acidity ntawm cov khoom noj, yog li txo cov kua qaub hauv plab ntawm cov tsiaj thiab nce cov kev ua ntawm pepsin.Nyob rau tib lub sijhawm, nws yuav cuam tshuam rau cov kua qaub ntawm cov hnyuv, thiab tom qab ntawd cuam tshuam rau kev tso tawm thiab kev ua haujlwm ntawm amylase, lipase thiab trypsin, txhawm rau txhim kho digestibility ntawm pub.

Ntxiv acidifier rau cov zaub mov ntawm weaned piglets tuaj yeem txo cov acidity ntawm pub, txhim kho cov kua qaub thiab nce kev siv tus nqi ntawm kev noj zaub mov hauv plab.Kev tshawb fawb ntawm Xing Qiyin thiab lwm tus tau pom tias thaum cov kua qaub zog ntawm cov khoom noj muaj tsawg, kev nthuav tawm ntawm cov pwm hauv cov khoom noj tuaj yeem tswj tau, cov kab mob pub mis tuaj yeem tiv thaiv tau, pub zaub tshiab tuaj yeem tswj tau, thiab cov kab mob raws plab. piglets yuav txo tau.

Lub luag haujlwm ntawm Acidifier hauv cov tsiaj yog qhia hauv daim duab hauv qab no, feem ntau suav nrog cov hauv qab no:

1) Nws tuaj yeem txo tus nqi pH hauv plab ntawm cov tsiaj thiab tom qab ntawd qhib qee qhov tseem ceeb digestive enzymes.Lub cev thiab tshuaj lom neeg cov khoom ntawm cov organic acids yuav cuam tshuam cov txiaj ntsig ntawm kev txo qis pH tus nqi ntawm plab hnyuv.Cov pKa qhov tseem ceeb ntawm malic acid, citric acid thiab fumaric acid yog nyob nruab nrab ntawm 3.0 thiab 3.5, belongs rau nruab nrab muaj zog acids, uas muaj peev xwm sai dissociate H + nyob rau hauv lub plab, txo cov acid theem nyob rau hauv lub plab, txhawb lub secretion ntawm pepsin, txhim kho cov hlab ntsha. digestive muaj nuj nqi, thiab tom qab ntawd ua tiav cov nyhuv acidification.

Cov kua qaub nrog cov qib sib txawv ntawm kev sib cais muaj qhov sib txawv.Hauv kev siv tswv yim, cov kua qaub nrog cov qib loj ntawm kev sib cais tuaj yeem raug xaiv los txo tus nqi pH ntawm txoj hnyuv, thiab cov kua qaub nrog cov qib me me ntawm kev sib cais tuaj yeem raug xaiv kom tsis muaj menyuam.

2) Acidifiers tuaj yeem tswj hwm microecological tshuav nyiaj li cas ntawm cov tsiaj plab hnyuv, rhuav tshem cov kab mob ntawm tes, cuam tshuam nrog kev sib txuas ntawm cov kab mob enzymes, ua tiav cov kab mob bacteriostatic lossis cov kab mob bactericidal, thiab yog li tiv thaiv cov kab mob hauv plab los ntawm cov kab mob pathogenic.

Feem ntau volatile organic acids thiab non-volatile organic acids muaj cov teebmeem bacteriostatic sib txawv, ntau hom thiab ntau npaum li cas ntawm Acidifiers, thiab sib txawv inhibitory thiab tua cov teebmeem ntawm cov kab mob pathogenic hauv plab hnyuv ntawm cov tsiaj.

Cov txiaj ntsig kev sim tau pom tias qhov siab tshaj plaws ntawm acidifier ntxiv rau hauv qhov pub yog 10 ~ 30kg / T, thiab kev siv ntau dhau tuaj yeem ua rau acidosis hauv cov tsiaj.Cui Xipeng et al.Pom tias ntxiv sib txawv proportions ntawmpoov tshuaj dicarboxylaterau pub muaj pom tseeb bacteriostatic nyhuv.Xav paub ntau ntxiv, qhov pom zoo ntxiv tus nqi yog 0.1%

3) Ua kom qeeb qeeb ntawm cov khoom noj hauv lub plab thiab txhawb kev zom zaub mov hauv plab thiab hnyuv.Manzanilla et al.Pom tau tias ntxiv 0.5% formic acid rau kev noj zaub mov ntawm cov piglets weaned tuaj yeem txo qis tus nqi ntawm plab hnyuv qhuav.

4) Txhim kho palatability.

5) Los tiv thaiv kev ntxhov siab, txhim kho kev loj hlob.

6) Txhim kho kev siv cov kab hauv cov khoom noj.
