Cov nyhuv ntawmpoov tshuaj dicarboxylatentawm plab hnyuv noj qab haus huv ntawm piglets

1) Bacteriostasis thiab sterilization

Cov txiaj ntsig ntawm kev ntsuas hauv vitro pom tias thaum pH yog 3 thiab 4,poov tshuaj dicarboxylateNws tuaj yeem cuam tshuam kev loj hlob ntawm Escherichia coli thiab lactic acid kab mob, tab sis thaum pH = 5, potassium dicarboxylate tsis cuam tshuam rau cov kab mob lactic acid thiab cov ciaj sia ntawm Escherichia coli poob qis.Potassium dicarboxylate muaj inhibitory cuam tshuam rau Salmonella c19-2, c19-12-77, porcine Escherichia coli el thiab Staphylococcus aureus.

Thaum 0.6% thiab 1.2% poov tshuaj dicarboxylate tau ntxiv rau kev noj haus ntawm cov piglets weaned, tus naj npawb ntawm Escherichia coli hauv duodenum, jejunum, txoj hnyuv thiab lub qhov quav tau txo qis [94].Ntxiv 0.6% poov tshuaj dicarboxylate tuaj yeem txo tus naj npawb ntawm Salmonella hauv cov zaub mov thiab quav, thiab txo qis qhov tshwm sim ntawm Salmonella thiab Escherichia coli hauv npua teb.Thaum 1.8% poov tshuaj dicarboxylate tau ntxiv rau kev noj zaub mov ntawm cov piglets weaned, tus naj npawb ntawm Escherichia coli hauv plab thiab cov hnyuv tau txo qis los ntawm 19.57% thiab 5.26%.

2) Qis plab hnyuv pH

Potassium dicarboxylatetuaj yeem txo lub plab thiab duodenal pH.Qhov sib ntxiv ntawm 0.9% poov tshuaj diacid nyob rau hauv cov zaub mov ntawm weaned piglets yuav txo tau lub plab pH (5.27 rau 4.92), tab sis nws tsis muaj kev cuam tshuam rau colonic chyme pH.Qhov sib ntxiv ntawm 0.6% lossis 1.2% potassium dicarboxylate hauv kev noj haus ntawm 28 hnub qub weaned piglets txo lub plab pH (los ntawm 4.4 txog 3.4), tab sis tsis muaj kev cuam tshuam rau pH ntawm duodenum, jejunum, ileum, cecum, txoj hnyuv thiab lub qhov quav.0.9% thiab 1.8% potassium dicarboxylate tau ntxiv rau cov zaub mov basal ntawm piglets.Tom qab pub mis rau 65 feeb, qhov sib ntxiv ntawm cov poov tshuaj dicarboxylate txo qis hauv duodenal pH, 0.32 thiab 0.40 hauv 0.9% pab pawg thiab 1.8% pawg, feem.Potassium dicarboxylate tuaj yeem txo qis pH hauv plab, txhawb kev tso tawm ntawm pepsin thiab txhim kho kev zom zaub mov thiab nqus cov protein.

3) Txhawb txoj hnyuv morphological kev ncaj ncees

Cov teebmeem ntawm 1%, 1.5% thiab 2% potassium dicarboxylate ntawm txoj hnyuv morphology ntawm weaned piglets tau kawm.Cov txiaj ntsig tau pom tias qhov siab ntawm duodenal plab hnyuv paperhair ntawm piglets ntxiv nrog 1.5% thiab 2% potassium dicarboxylate tau nce siab dua li ntawm pawg tswj hwm tsis muaj potassium dicarboxylate (0.78mm hauv pawg tswj hwm, 0.98mm hauv 1.5% potassium dicarboxylate pawg. thiab 0.90min hauv 2.0% poov tshuaj dicarboxylate pawg), Txawm li cas los xij, qhov sib ntxiv ntawm qhov sib txawv ntawm cov poov tshuaj dicarboxylate tsis tau txhim kho txoj hnyuv villus qhov siab ntawm jejunum thiab ileum.

 

Cov txiaj ntsig ntawm potassium dicarboxylate rau kev ua haujlwm ntawmWeaned Piglets

1) Txhawb cov ntxhia nqus dej

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

2) Txhim kho kev hloov pauv pub

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

Cov txiaj ntsig tau pom tiaspoov tshuaj dicarboxylatetuaj yeem txo qis kev ntxhov siab, txhawb kev loj hlob thiab plab hnyuv siab ntawm piglets.
