Tus nqi ntawm potassium diformate hauv kev ua liaj ua teb nqaij qaib:

Cov tshuaj tua kab mob tseem ceeb (txo Escherichia coli los ntawm ntau dua 30%), txhim kho kev hloov pauv hloov pauv hloov pauv los ntawm 5-8%, hloov cov tshuaj tua kab mob kom txo tau raws plab los ntawm 42%. Qhov hnyav nce ntawm broiler qaib yog 80-120 grams rau ib tug qaib, lub qe qe qe ntawm nteg qe yog nce los ntawm 2-3%, thiab cov txiaj ntsig zoo tau nce los ntawm 8% -12%, uas yog qhov tseem ceeb ntawm kev ua liaj ua teb ntsuab.

Potassium diformate, raws li hom tshiab ntawm cov khoom noj ntxiv, tau pom cov txiaj ntsig tseem ceeb hauv kev ua liaj ua teb nqaij qaib hauv xyoo tas los no. Nws cov tshuaj tua kab mob tshwj xeeb, txhawb kev loj hlob, thiab kev txhim kho txoj hnyuv hauv lub cev muab cov tshuaj tshiab rau kev noj qab haus huv nqaij qaib ua liaj ua teb.

1, Lub cev thiab tshuaj lom neeg thiab kev ua haujlwm ntawm cov poov tshuaj diformate

Potassium diformateyog ib tug crystalline compound tsim los ntawm kev sib xyaw ntawm formic acid thiab poov tshuaj diformate nyob rau hauv ib tug 1: 1 molar piv, nrog rau cov mis molecular CHKO ₂. Nws zoo nkaus li dawb crystalline hmoov thiab yooj yim soluble hauv dej. Cov organic acid ntsev no tseem nyob ruaj khov nyob rau hauv ib puag ncig acidic, tab sis tuaj yeem sib cais thiab tso tawm formic acid thiab potassium diformate nyob rau hauv nruab nrab lossis tsis muaj zog alkaline ib puag ncig (xws li nqaij qaib plab hnyuv). Nws tus nqi tshwj xeeb yog nyob rau hauv qhov tseeb tias formic acid yog cov saw luv fatty acid nrog cov tshuaj tua kab mob uas muaj zog tshaj plaws ntawm cov organic acids paub, thaum potassium ions tuaj yeem ntxiv cov electrolytes, thiab ob qho tib si ua haujlwm ua ke.

Cov nyhuv antibacterial ntawmpoov tshuaj diformateyog ua tiav los ntawm peb txoj hauv kev:

Lub dissociated formic acid molecules tuaj yeem nkag mus rau cov kab mob hauv cov kab mob ntawm tes, txo cov pH ntawm lub cev, thiab cuam tshuam nrog cov kab mob microbial enzyme thiab kev thauj khoom noj khoom haus;
Unsolved formic acid nkag mus rau hauv cov kab mob hlwb thiab decomposes rau hauv H ⁺ thiab HCOO ⁻, cuam tshuam cov qauv ntawm cov kab mob nucleic acids, tshwj xeeb tshaj yog nthuav tawm cov teebmeem tseem ceeb ntawm cov kab mob Gram tsis zoo xws li Salmonella thiab Escherichia coli.

Kev tshawb fawb tau pom tias ntxiv 0.6% potassium formate tuaj yeem txo tus naj npawb ntawm Escherichia coli hauv cecum ntawm broiler qaib ntau dua 30%;

Los ntawm inhibiting kev loj hlob ntawm cov kab mob phem, indirectly txhawb lub colonization ntawm cov kab mob zoo xws li cov kab mob lactic acid, thiab txhim kho qhov sib npaug ntawm plab hnyuv microbiota.

2 、 Cov txheej txheem tseem ceeb ntawm kev ua haujlwm hauv kev ua liaj ua teb nqaij qaib
1. Ua kom muaj zog tiv thaiv kab mob, txo cov kab mob hnyav

Cov nyhuv antibacterial ntawm potassium diformate yog ua tiav los ntawm peb txoj hauv kev:
Lub dissociated formic acid molecules tuaj yeem nkag mus rau cov kab mob hauv cov kab mob ntawm tes, txo cov pH ntawm lub cev, thiab cuam tshuam nrog cov kab mob microbial enzyme thiab kev thauj khoom noj khoom haus;
Unsolved formic acid nkag mus rau hauv cov kab mob hlwb thiab decomposes rau hauv H ⁺ thiab HCOO ⁻, cuam tshuam cov qauv ntawm cov kab mob nucleic acids, tshwj xeeb tshaj yog nthuav tawm cov teebmeem tseem ceeb ntawm cov kab mob Gram tsis zoo xws li Salmonella thiab Escherichia coli. Kev tshawb fawb tau pom tias ntxiv 0.6% potassium diformate tuaj yeem txo tus naj npawb ntawm Escherichia coli hauv cecum ntawm qaib broiler ntau dua 30%;
Los ntawm inhibiting kev loj hlob ntawm cov kab mob phem, indirectly txhawb lub colonization ntawm cov kab mob zoo xws li cov kab mob lactic acid, thiab txhim kho qhov sib npaug ntawm plab hnyuv microbiota.

2. Txhim khu kev zom zaub mov thiab txhim kho kev noj zaub mov kom zoo

Txo tus nqi pH ntawm txoj hnyuv, qhib pepsinogen, thiab txhawb kev zom cov protein;
Txhawb nqa kev tso tawm ntawm digestive enzymes hauv lub txiav, txhim kho kev zom cov hmoov txhuv nplej siab thiab rog. Kev sim cov ntaub ntawv qhia tau hais tias ntxiv 0.5% poov tshuaj diformate rau broiler pub tuaj yeem nce pub hloov pauv ntawm 5-8%;

Tiv thaiv txoj hnyuv villus qauv thiab ua rau kom qhov chaw nqus ntawm cov hnyuv me. Electron microscopy soj ntsuam pom tau hais tias lub villus qhov siab ntawm jejunum nyob rau hauv broiler qaib kho nrog poov tshuaj formate tau nce 15% -20% piv rau pawg tswj.

Suav Ministry of Agriculture (2019). Nws txo qhov tshwm sim ntawm raws plab los ntawm ntau yam mechanisms. Hauv 35 hnub qub dawb feathered broiler sim, qhov sib ntxiv ntawm 0.8%poov tshuaj diformatetxo tus mob raws plab los ntawm 42% piv rau cov pab pawg neeg dawb paug, thiab cov nyhuv zoo ib yam li cov tshuaj tua kab mob.
3, Daim ntawv thov cov txiaj ntsig hauv kev tsim khoom tiag

1. Kev ua tau zoo hauv kev ua liaj ua teb broiler
Kev loj hlob: Thaum muaj hnub nyoog 42 hnub, qhov nruab nrab qhov hnyav nce rau kev tua yog 80-120 grams, thiab qhov sib xws yog txhim kho los ntawm 5 feem pua ​​​​ntawm cov ntsiab lus;

Kev txhim kho nqaij zoo: txo cov leeg hauv siab drip poob thiab txuas lub neej txee. Qhov no tej zaum yuav muaj feem xyuam rau nws txo qis oxidative kev nyuaj siab, nrog rau cov ntshav MDA txo los ntawm 25%;

Cov txiaj ntsig kev lag luam: xam raws li tus nqi pub noj tam sim no, txhua tus qaib tuaj yeem nce nyiaj tau los ntawm 0.3-0.5 yuan.
2. Daim ntawv thov nyob rau hauv qe qaib ntau lawm
Lub qe ntau lawm yog nce los ntawm 2-3%, tshwj xeeb tshaj yog rau nteg hens tom qab lub ncov lub sij hawm;

Kev txhim kho hauv cov qe zoo, nrog rau 0.5-1 feem pua ​​​​cov ntsiab lus txo qis hauv cov qe tawg, vim qhov nce hauv calcium nqus efficiency;

Qhov tseem ceeb txo qhov concentration ntawm ammonia hauv cov quav (30% -40%) thiab txhim kho qhov chaw sab hauv tsev.

Qhov tshwm sim ntawm nqaij qaib plab o tau txo qis, thiab 7-hnub muaj sia nyob tus nqi nce 1.5-2%.

4 、 Kev npaj siv txuj ci thiab kev ceev faj
1. Pom zoo tus nqi ntxiv

Broiler: 0.5% -1.2% (siab nyob rau theem pib, qis hauv theem tom qab);
Qe nteg qe: 0.3% -0.6%;
Cov dej haus ntxiv: 0.1% -0.2% (yuav tsum tau siv nrog acidifiers).

2. Kev txawj ua tau zoo
Kev siv dag zog nrog probiotics thiab cog cov roj tseem ceeb tuaj yeem txhim kho cov nyhuv;
Tsis txhob sib tov ncaj qha nrog cov tshuaj alkaline (xws li baking soda);
Tus nqi ntawm cov tooj liab ntxiv rau cov khoom noj tooj liab siab yuav tsum tau nce 10% -15%.

3. Cov ntsiab lus tseem ceeb ntawm kev tswj kom zoo
Xaiv cov khoom uas muaj purity ntawm ≥ 98%, thiab cov impurity (xws li hnyav hlau) cov ntsiab lus yuav tsum ua raws li tus qauv GB / T 27985;
Khaws rau hauv qhov chaw txias thiab qhuav, siv sai li sai tau tom qab qhib;
Ua tib zoo saib xyuas qhov sib npaug ntawm cov calcium hauv cov khoom noj, vim tias kev noj ntau dhau yuav cuam tshuam rau kev nqus cov ntxhia.

5 、 Kev Txhim Kho Yav Tom Ntej
Nrog rau txoj kev loj hlob ntawm precision khoom noj khoom haus technology, qeeb-tso formulations thiab microencapsulated cov khoom ntawm poov tshuaj diformate yuav ua rau kev tshawb fawb thiab kev loj hlob kev taw qhia. Raws li tus qauv ntawm kev txo cov tshuaj tua kab mob hauv kev ua liaj ua teb nqaij qaib, kev sib xyaw ua haujlwm ntawm oligosaccharides thiab kev npaj enzyme yuav ntxiv dag zog rau kev tsim cov nqaij qaib. Nws yog ib qho tsim nyog sau cia tias qhov kev tshawb fawb zaum kawg los ntawm Suav Academy ntawm Kev Tshawb Fawb Txog Kev Ua Liaj Ua Teb hauv xyoo 2024 pom tias potassium formate tuaj yeem txhim kho txoj hnyuv tiv thaiv kab mob los ntawm kev tswj hwm TLR4 / NF - κ B signaling pathway, muab lub hauv paus tshiab theoretical rau nws txoj kev loj hlob.

Kev xyaum tau qhia tias kev siv lub laj thawjpoov tshuaj diformatetuaj yeem nce cov txiaj ntsig zoo ntawm kev ua liaj ua teb nqaij qaib los ntawm 8% -12%, tab sis nws cov txiaj ntsig tau cuam tshuam los ntawm yam xws li kev tswj hwm kev noj zaub mov thiab kev noj zaub mov yooj yim.

Cov neeg ua liaj ua teb yuav tsum ua qhov kev sim ntsuas gradient raws li lawv tus kheej tej yam kev mob los nrhiav qhov zoo tshaj plaws daim ntawv thov kev npaj thiab siv tag nrho cov nyiaj txiag thiab ecological tus nqi ntawm no ntsuab additive.
