calcium formate muaj tus nqi zoo

tus cwj pwm

Ca (HCOO) 2, molecular yuag: 130.0 Specific gravity: 2.023 (20 ℃ deg.c), bulk ntom 900-1000g / kg,

PH tus nqi yog nruab nrab, decomposition ntawm 400 ℃. Cov ntsiab lus ntsuas ≥98%, dej ≤0.5%, calcium ≥30%. Calcium formate yog dawb los yog daj me ntsis hmoov los yog siv lead ua, tsis muaj tshuaj lom, iab saj, insoluble nyob rau hauv cawv, tsis delixing, soluble nyob rau hauv dej, aqueous tov yog nruab nrab, tsis muaj tshuaj lom. Solubility ntawm calcium formate tsis hloov ntau nrog qhov kub thiab txias, 16g / 100g dej ntawm 0 ℃, 18.4g / 100g dej ntawm 100 ℃, thiab decomposition ntawm 400 ℃.

Action mechanism

Calcium formate, raws li hom tshiab pub additive tsim nyob rau hauv tsev thiab txawv teb chaws, muaj ntau yam kev siv, haum rau txhua yam tsiaj pub raws li acidifying tus neeg saib xyuas, mildew tiv thaiv tus neeg sawv cev, antibacterial agent, yuav hloov citric acid, fumaric acid thiab lwm yam pub acidifying tus neeg sawv cev siv, tuaj yeem txo thiab tswj cov kab mob plab PH tus nqi, txhawb kev zom zaub mov thiab nqus cov as-ham, thiab muaj kev tiv thaiv kab mob thiab kev saib xyuas kev noj qab haus huv. Tshwj xeeb tshaj yog rau piglets, cov nyhuv tseem ceeb dua.

Raws li pub additive, calcium formate yog tshwj xeeb tshaj yog haum rau weaned piglets. Nws tuaj yeem cuam tshuam rau kev loj hlob ntawm cov kab mob hauv plab hnyuv, qhib pepsinogen, txhim kho kev siv lub zog ntawm cov metabolites, txhim kho kev noj zaub mov hloov pauv, tiv thaiv kab mob raws plab, dysenter, txhim kho cov ciaj sia taus thiab qhov hnyav nce txhua hnub ntawm piglets. Nyob rau tib lub sijhawm, calcium formate kuj muaj cov txiaj ntsig ntawm kev tiv thaiv pwm thiab ua kom tshiab.

Nyob rau hauv xyoo tas los no, tag nrho cov txheej txheem pub noj tau zoo tuaj sai heev. Cov khoom noj pub mis feem ntau yog txaus los yog ntau dhau. Dab tsi yuav tsum tau daws tam sim no yog kev hloov cov tshuaj tua kab mob, mycotoxins thiab kev ua kom zoo ntawm kev siv khoom noj khoom haus. Lub tswv yim ntawm "feed acid zog" kuj tau them ntau thiab ntau xim raws li ib qho tseem ceeb parameter ntsuas pH qib ntawm pub.

Raws li peb txhua tus paub, kev zom, nqus, tiv thaiv kab mob thiab lwm yam kev ua neej nyob hauv ntau yam tsiaj yuav tsum tau ua nyob rau hauv ib puag ncig dej uas tsim nyog PH. Tus nqi PH ntawm txoj hnyuv yog nruab nrab, thiab digestive enzymes thiab ntau yam kab mob muaj txiaj ntsig tuaj yeem ua lub luag haujlwm zoo dua. Txwv tsis pub, kev zom zaub mov thiab nqus tau qis, cov kab mob ua rau cov kab mob tsis zoo, tsis yog raws plab xwb, tab sis kuj cuam tshuam rau kev noj qab haus huv thiab kev tsim khoom ntawm lub cev tsiaj. Nyob rau hauv cov theem ntawm Suckling piglets, cov tub ntxhais hluas npua lawv tus kheej muaj kev tsis zoo thiab tsis txaus tso tawm ntawm plab acid thiab digestive enzymes. Yog tias kev noj zaub mov acid siab, ntau yam teeb meem feem ntau tshwm sim.

Thov

Cov kev sim tau pom tias ntxiv calcium formate rau pub tuaj yeem tso cov kab mob ntawm formic acid hauv cov tsiaj, txo cov PH tus nqi ntawm lub plab zom mov, thiab muaj cov nyhuv buffering, uas yog qhov zoo rau kev ruaj ntseg ntawm PH nqi hauv plab hnyuv, Yog li inhibiting kev loj hlob ntawm cov kab mob tsis zoo thiab txhawb kev loj hlob ntawm cov kab mob uas muaj txiaj ntsig zoo, xws li kev loj hlob ntawm lactobacillus, thiaj li npog cov hnyuv mucosa los ntawm kev cuam tshuam ntawm co toxins. Txhawm rau tswj thiab tiv thaiv qhov tshwm sim ntawm cov kab mob ntsig txog raws plab, kab mob plab thiab lwm yam tshwm sim, qhov sib ntxiv yog feem ntau 0.9% -1.5%. Calcium formate raws li acidifier, piv nrog citric acid, nyob rau hauv cov txheej txheem pub ntau lawm yuav tsis delix, zoo fluidity, PH tus nqi nruab nrab, yuav tsis ua rau cov khoom siv corrosion, ncaj qha ntxiv rau pub tuaj yeem tiv thaiv cov vitamins thiab amino acids thiab lwm cov as-ham raug puas tsuaj. , yog ib qho zoo tagnrho pub acidifier, tuaj yeem hloov cov citric acid, fumaric acid thiab lwm yam.

Ib txoj kev tshawb fawb German pom tias calcium formate ntxiv rau piglet noj los ntawm 1.3% tuaj yeem txhim kho kev hloov pauv pub noj los ntawm 7-8%; Ntxiv ntawm 0.9% tuaj yeem txo qhov tshwm sim ntawm raws plab; Ntxiv 1.5% tuaj yeem txhim kho qhov kev loj hlob ntawm piglets los ntawm 1.2%, thiab pub hloov pauv tus nqi los ntawm 4%. Ntxiv 1.5% qib 175mg / kg tooj liab tuaj yeem nce tus nqi loj hlob los ntawm 21% thiab pub hloov pauv tus nqi los ntawm 10%. Cov kev tshawb fawb hauv tsev tau pom tias ntxiv 1-1.5% calcium formate rau thawj 8 hnub Sunday noj zaub mov ntawm piglets tuaj yeem tiv thaiv kev mob raws plab thiab raws plab, txhim kho kev ciaj sia, nce kev hloov pauv hloov pauv ntawm 7-10%, txo kev noj zaub mov los ntawm 3.8%, thiab nce ntxiv. qhov nce txhua hnub ntawm npua los ntawm 9-13%. Ntxiv calcium formate rau silage tuaj yeem nce cov ntsiab lus ntawm lactic acid, txo cov ntsiab lus ntawm casein thiab nce cov khoom noj muaj pes tsawg leeg ntawm silage.

Raws li pub additive, calcium formate yog tshwj xeeb tshaj yog haum rau weaned piglets. Nws tuaj yeem cuam tshuam rau kev loj hlob ntawm cov kab mob hauv plab hnyuv, qhib pepsinogen, txhim kho kev siv lub zog ntawm cov metabolites, txhim kho kev noj zaub mov hloov pauv, tiv thaiv kab mob raws plab thiab raws plab, thiab txhim kho cov ciaj sia taus thiab qhov hnyav nce txhua hnub ntawm piglets.

Raws li hom tshiab pub additive tsim nyob rau hauv tsev thiab txawv teb chaws, pub qib calcium formate yog dav siv nyob rau hauv tag nrho cov hom tsiaj pub raws li ib tug acidifier, mildew tiv thaiv tus neeg sawv cev, antibacterial neeg sawv cev, yuav txo tau thiab tswj lub plab zom mov PH nqi, txhawb kev zom thiab nqus. ntawm cov as-ham, thiab muaj kev tiv thaiv kab mob thiab kev saib xyuas kev noj qab haus huv, tshwj xeeb tshaj yog rau piglets tseem ceeb dua.

Lub zog acid ntawm pub yog feem ntau cuam tshuam los ntawm kev siv cov zaub mov inorganic (xws li pob zeb hmoov, uas muaj cov kua qaub zog ntau dua 2800). Txawm hais tias siv ntau npaum li cas ntawm fermented soybean pluas noj, cov kua qaub zog tseem nyob deb ntawm qhov zoo tagnrho (kev lag luam feem ntau ntseeg tias lub zog acid ntawm piglet pub yuav tsum yog 20-30). Kev daws yog ntxiv cov organic acids ntxiv, lossis ncaj qha hloov cov inorganic acids nrog cov organic acids. Feem ntau, thawj qhov kev txiav txim siab yog hloov pob zeb hmoov (calcium).

Feem ntau siv cov organic calcium los yog acidifiers yog calcium lactate, calcium citrate, thiab calcium formate. Txawm hais tias calcium lactate muaj ntau qhov zoo, cov ntsiab lus calcium tsuas yog 13%, thiab tus nqi ntxiv yog siab dhau lawm, thiab nws feem ntau tsuas yog siv rau hauv cov ntaub ntawv qhia qib siab. Calcium citrate, yog nruab nrab, dej solubility tsis zoo, muaj calcium 21%, yav tas los xav tias palatability zoo, qhov tseeb tsis yog li ntawd. Calcium formate tau lees paub los ntawm ntau thiab ntau cov tuam txhab pub khoom noj vim tias nws cov ntsiab lus calcium siab (30%), cov tshuaj tua kab mob zoo ntawm cov molecule formic acid me me, thiab nws cov nyhuv secretory ntawm qee cov proteases.

Kev thov thaum ntxov ntawm calcium sulfate tsis yog dav, tab sis kuj muaj feem xyuam rau nws qhov zoo. Qee qhov pov tseg (para-) calcium formate yog khaus ntau dua. Qhov tseeb, qhov zoo tiag tiag acid calcium ua los ntawm cov khoom, txawm tias tseem me ntsis ntawm calcium formate cim micro iab, tab sis deb ntawm kev cuam tshuam palatability. Qhov tseem ceeb yog kev tswj cov khoom zoo.

Raws li ib qho yooj yim acid ntsev, calcium formate zoo tuaj yeem paub qhov txawv ntawm qhov dawb, crystallinity, transparency, dispersion thiab meltwater thwmsim. Hauv paus ntsiab lus, nws qhov zoo nyob ntawm qhov zoo ntawm ob cov khoom siv raw. Txhua yam ntawm cov txheej txheem nqi yog pob tshab, thiab koj tau txais yam koj them rau.

Thaum calcium formate yog siv los pub, 1.2-1.5kg ntawm pob zeb hmoov tuaj yeem hloov tau rau 1kg, uas txo cov kua qaub zog ntawm tag nrho cov khoom noj los ntawm ntau dua 3 cov ntsiab lus. Txhawm rau ua tiav cov txiaj ntsig zoo ib yam, nws cov nqi qis dua li calcium citrate. Tau kawg, cov tshuaj tiv thaiv kab mob kuj tuaj yeem txo cov zinc oxide thiab tshuaj tua kab mob.

Tam sim no feem ntau siv cov tshuaj acidifiers kuj muaj calcium formate, thiab txawm tias calcium formate nyiaj rau ze li ntawm 70% lossis 80%. Qhov no kuj lees paub lub luag haujlwm thiab qhov tseem ceeb ntawm calcium formate. Qee cov neeg tsim khoom siv calcium formate ua cov khoom tseem ceeb.

Raws li qhov tam sim no tide ntawm kev tsis kam, cov khoom siv acidifier thiab cog cov roj tseem ceeb, kev npaj micro-ecological, thiab lwm yam, muaj lawv tus kheej cov teebmeem. Calcium formate raws li cov khoom sib txawv hauv cov kua qaub, tsis hais cov txiaj ntsig lossis nqi, yog qhov tsim nyog tshaj plaws ntawm kev txiav txim siab thiab hloov pauv.
