Kev ua haujlwm ntawmpotassium dicarboxylatentawm kev noj qab haus huv ntawm cov menyuam npua

1) Bacteriostasis thiab sterilization

Cov txiaj ntsig ntawm kev sim hauv vitro qhia tau tias thaum pH yog 3 thiab 4,potassium dicarboxylatetuaj yeem tiv thaiv kev loj hlob ntawm Escherichia coli thiab lactic acid bacteria, tab sis thaum pH = 5, potassium dicarboxylate tsis muaj txiaj ntsig rau lactic acid bacteria thiab tus nqi ciaj sia ntawm Escherichia coli txo qis. Potassium dicarboxylate muaj cov teebmeem inhibitory rau Salmonella c19-2, c19-12-77, porcine Escherichia coli el thiab Staphylococcus aureus.

Thaum ntxiv 0.6% thiab 1.2% potassium dicarboxylate rau hauv cov zaub mov ntawm cov menyuam npua uas tsis tau noj mis, tus lej ntawm Escherichia coli hauv duodenum, jejunum, plab hnyuv loj thiab qhov quav txo qis [94]. Ntxiv 0.6% potassium dicarboxylate tuaj yeem txo tus lej ntawm Salmonella hauv cov zaub mov thiab cov quav, thiab txo qhov tshwm sim ntawm Salmonella thiab Escherichia coli hauv cov liaj teb npua. Thaum ntxiv 1.8% potassium dicarboxylate rau hauv cov zaub mov ntawm cov menyuam npua uas tsis tau noj mis, tus lej ntawm Escherichia coli hauv plab thiab txoj hnyuv me me txo qis los ntawm 19.57% thiab 5.26%.

2) Qis dua pH ntawm txoj hnyuv

Potassium dicarboxylatetuaj yeem txo qhov pH ntawm lub plab thiab duodenum. qhov ntxiv ntawm 0.9% potassium diacid hauv cov zaub mov ntawm cov menyuam npua uas tsis tau noj mis tuaj yeem txo qhov pH ntawm lub plab (5.27 txog 4.92), tab sis nws tsis muaj qhov cuam tshuam rau colonic chyme pH. Qhov ntxiv ntawm 0.6% lossis 1.2% potassium dicarboxylate hauv cov zaub mov ntawm cov menyuam npua uas tsis tau noj mis 28 hnub tau txo qhov pH ntawm lub plab (los ntawm 4.4 txog 3.4), tab sis tsis muaj qhov cuam tshuam rau qhov pH ntawm duodenum, jejunum, ileum, cecum, colon thiab rectum. 0.9% thiab 1.8% potassium dicarboxylate tau ntxiv rau cov zaub mov tseem ceeb ntawm cov menyuam npua. Tom qab pub mis rau 65 feeb, qhov ntxiv ntawm potassium dicarboxylate tau txo qhov pH ntawm lub plab, 0.32 thiab 0.40 hauv 0.9% pawg thiab 1.8% pawg, feem. Potassium dicarboxylate tuaj yeem txo qhov pH ntawm lub plab, txhawb kev tso pa tawm ntawm pepsin thiab txhim kho kev zom zaub mov thiab kev nqus cov protein.

3) Txhawb kev ncaj ncees ntawm txoj hnyuv

Cov teebmeem ntawm 1%, 1.5% thiab 2% potassium dicarboxylate rau ntawm cov qauv plab hnyuv ntawm cov menyuam npua uas tsis tau noj mis tau raug kawm. Cov txiaj ntsig tau qhia tias qhov siab ntawm cov plaub hau plab hnyuv ntawm cov menyuam npua uas ntxiv nrog 1.5% thiab 2% potassium dicarboxylate siab dua li ntawm pawg tswj tsis muaj potassium dicarboxylate (0.78mm hauv pawg tswj, 0.98mm hauv pawg 1.5% potassium dicarboxylate thiab 0.90min hauv pawg 2.0% potassium dicarboxylate), Txawm li cas los xij, qhov ntxiv ntawm cov feem sib txawv ntawm potassium dicarboxylate tsis tau txhim kho qhov siab ntawm jejunum thiab ileum ntawm plab hnyuv.

 

Cov nyhuv ntawm potassium dicarboxylate rau kev ua haujlwm ntawmCov menyuam npua uas tsis tau noj mis

1) Txhawb kev nqus cov ntxhia

Cov txiaj ntsig qhia tau tias potassium dicarboxylate tuaj yeem txhawb kev nqus cov zaub mov thiab ua rau kom muaj kev nqus ntawm phosphorus, magnesium, zinc, tooj liab thiab manganese los ntawm 8% - 9%, 3% - 8%, 9% - 17%, 52% - 60% thiab 6% feem. Kev sim ntawm kev ua tiav npua qhia tau tias kev ntxiv 1% potassium dicarboxylate tuaj yeem ua rau kom muaj kev zom zaub mov ntawm cov protein nyoos los ntawm 4.34% thiab kev siv phosphorus los ntawm 1.75%. Potassium dicarboxylate tuaj yeem txhawb kev nqus cov as-ham thiab tswj kev tsim cov tshuaj lom. Ntxiv 0.9% thiab 1.8% potassium dicarboxylate rau cov menyuam npua pub tuaj yeem txo cov ntsiab lus ntawm ammonia hauv plab, thiab cov nyhuv ntawm 0.9% potassium dicarboxylate yog qhov tseem ceeb tshaj plaws.

2) Txhim kho kev hloov pauv pub mis

Ntxiv 1.8% potassium dicarboxylate rau hauv cov zaub mov ntawm 9-21kg piglets tuaj yeem ua rau kom muaj kev loj hlob ntawm 32.7% thiab qhov hloov pauv pub ntawm 12.2%, uas yog sib npaug rau 40ppm telosin phosphate. Thaum ntxiv 1.8% dicarboxylic acid rau hauv cov zaub mov ntawm cov piglets uas tsis tau noj mis nrog qhov hnyav ntawm 7kg thiab qib zog metabolic yog 13mj / kg lossis 14mj / kg, potassium dicarboxylate tuaj yeem ua rau kom muaj qhov hnyav ntawm cov piglets los ntawm 5% thiab 12% feem; Kev nce txhua hnub nce 8% thiab 18% feem; Tus nqi hloov pauv pub nce 6%; Qhov nruab nrab ntawm kev noj zaub mov txhua hnub nce 1% thiab 8% feem.

Cov txiaj ntsig tau qhia tiaspotassium dicarboxylateyuav txo tau kev ntxhov siab ntawm kev rho menyuam, txhawb kev loj hlob thiab kev ua haujlwm ntawm cov menyuam npua.
