Daim ntawv thov ntawm Ordinary Zinc Oxid hauv Kev Tiv Thaiv Kab Mob ntawm Piglets

III. Teeb meem ntawm raws plab nyob rau hauv weaned piglets thiab cov nqi kho mob ntawmzinc oxide

Weaning yog ib qho kev ntxhov siab loj hauv lub neej ntawm tus npua. Cov teeb meem xws li kev ua haujlwm tsis muaj zog hauv plab hnyuv, kev tso tawm tsis txaus ntawm digestive enzymes, thiab kev tsis sib haum xeeb ntawm cov nroj tsuag feem ntau ua rau mob plab zawv plab (PWD), uas ua rau muaj kev hem thawj rau kev loj hlob thiab kev yug me nyuam ntawm piglets. Txij li qhov qubzinc oxidetau pom tias muaj qhov cuam tshuam rau kev noj qab haus huv tseem ceeb hauv xyoo 1980, nws tau dhau los ua "tus qauv kub" rau kev lag luam tsiaj txhu thoob ntiaj teb los cuam tshuam nrog PWD. Cov kev tshawb fawb tau pom tias ntxiv 2500-3000 mg / kgzinc oxidetuaj yeem txo qhov mob raws plab los ntawm 40% -60%, thaum nce qhov hnyav txhua hnub los ntawm 10% -15%. Nws cov txiaj ntsig tseem ceeb nyob hauv kev ruaj khov ntawm txoj hnyuv ib puag ncig los ntawm ntau lub tshuab, muab kev tiv thaiv kev hloov pauv tseem ceeb rau piglets.

IV.Lub mechanism ntawm kev ua ntawmzinc oxidetiv thaiv raws plab

1)Strengthening plab hnyuv lub cev barrier

Zinc oxidetxhawb kev loj hlob ntawm plab hnyuv epithelial hlwb, nce qhov sib piv ntawm plab hnyuv siab rau crypt qhov tob, txhim kho thaj chaw saum npoo rau kev nqus cov as-ham, thiab ib txhij upregulates qhov kev nthuav qhia ntawm nruj hlws ris proteins (Occludin, ZO-1), txo cov hnyuv mucosal permeability, thiab thaiv cov kab mob. Nws tiv thaiv txoj hnyuv mucosal barrier muaj nuj nqi, txhim kho cov kab mob muaj peev xwm ntawm piglets, thiab txo qhov mob raws plab.

2)Regulating plab hnyuv microbial tshuav nyiaj li cas

Zinc oxidetsim hydrogen peroxide dawb radicals nyob rau hauv txoj hnyuv, uas yog ib qho tseem ceeb ntawm cov tshuaj tua kab mob.zinc oxide. Cov koob tshuaj ntauzinc oxidencaj qha inhibits kev loj hlob ntawm cov kab mob pathogenic xws li Escherichia coli thiab Salmonella los ntawm kev tso tawm cov pa oxygen reactive (ROS), thaum txhawb kev colonization ntawm cov kab mob zoo xws li Lactobacillus.

3) High zinc txhawb kev loj hlob ntawm piglets

Kev ntxhov siab tsis pub dhau 30% txo qis hauv kev noj zaub mov digestibility, thiab digestibility ntawm cov as-ham hauv weaned piglets ntxiv txo qis thaum lawv nyob rau hauv lub xeev raws plab. Cov kev tshawb fawb tau qhiauasntxiv cov koob tshuaj ntauzinc oxiderau kev noj zaub mov tuaj yeem nce qib zinc hauv cov ntshav, ntxiv tswj qhov tso tawm ntawm lub paj hlwb plab peptides thiab cov tshuaj hormones tshaib plab, thiabtxhawb nqa npua noj. Tib lub sijhawm, nce zinc cov ntsiab lus hauv cov ntshavua tauzoo txhawb lub synthesis thiab activation ntawm digestive enzymes, txhim kho digestibility ntawm cov as-ham, thiabnce qhov hnyav txhua hnub ntawm piglets.

IV. Daim ntawv thov kev tshawb fawb thiab kev ceev faj

1. Muaj tseeb npaum li cas thiab kev siv lub voj voog

Txawm hais tias nws tau teev tseg tias zinc siab (1600-2500 mg / kgzinc oxide) pub tsuas yog siv tau rau hauv”thawj ob lub lis piam tom qab weaning”, ntau tus npua teb txuas ntxiv siv cov zinc pub rau 2-8 lub lis piam. Lub sijhawm no, qee tus npua teb yuav ntsib”siab zinc phiv”, uas feem ntau manifested li tuab thiab ntev plaub hau thiab dull daim tawv nqaij.

2. Xaivzinc oxidenrog siab stability los txhim kho cov khoom siv

Bioavailability ntawmzinc oxideua los ntawm cov txheej txheem ntub dej yog qhov siab dua li ntawmzinc oxidetsim los ntawm cov txheej txheem ncaj qha. Yog li ntawd, thaum xaivzinc oxidecov khoom, nws cov txheej txheem ntau lawm yuav tsum tau txiav txim siab.

5. Kev Lag Luam Trends thiab Alternative Technology Outlook

Txawm hais tias EU tau txwv cov zinc ntxiv rau 150 mg / kg, kev coj ua hauv tsev qhia tau hais tias tag nrho hloov cov zinc siab tseem tab tom ntsib kev tsis sib haum xeeb. Tam sim no lwm yam xws li nanozinc oxide(300 mg / kg) thiab zinc chloride yooj yim (1200 mg / kg) tuaj yeem txo qhov ntau npaum, tab sis lawv cov nqi siab, cov txheej txheem ruaj khov tsis txaus, thiab kev nyab xeeb mus sij hawm ntev tseem yuav tsum tau kuaj xyuas. Yog li ntawd,zoo tib yamzinc oxidetseem yog qhov kev xaiv zoo tshaj plaws rau cov liaj teb me thiab nruab nrab kom sib npaug ntawm cov nqi thiab cov txiaj ntsig.
