Lentinan (LNT) yog cov khoom tseem ceeb hauv cov nceb, uas muaj lub luag haujlwm ntawm kev txhawb lub cev tiv thaiv kab mob, tshuaj tua kab mob thiab tshuaj tua kab mob, tswj cov hnyuv microecological tshuav nyiaj li cas, tiv thaiv oxidation thiab txhim kho tsiaj txhu thiab nqaij qaib kev ua haujlwm. Nyob rau hauv xyoo tas los no, nws tau raug siv los ua cov tshuaj tua kab mob zoo hloov nws tau dav ntxiv rau kev pub additives thiab ntau lawm.
1. Raws li kev hloov tshuaj tua kab mob thiab qee yam tshuaj tiv thaiv kab mob
Los ntawm kev kawm txog cov kab mob fungal polysaccharides tuaj yeem siv los hloov cov tshuaj tua kab mob thiab qee cov tshuaj tiv thaiv kab mob. Txoj kev tshawb no ntawm cov kab mob los tiv thaiv Newcastle tus kab mob tiv thaiv ntawm extracellular polysaccharides fermented los ntawm Grifola frondosa strains nyob rau theem ntawm cov nqaij qaib embryos tuaj yeem qhia tau hais tias cov extracellular polysaccharides fermented los ntawm Grifola frondosa muaj kev cuam tshuam zoo rau cov kab mob Newcastle, ua kom qeeb thiab txo qis. Kev tuag ntawm qaib embryos, thiab txo hemagglutination. Lub titer muaj qee yam kev tua neeg ntawm tus kab mob Newcastle. Compound pub additives tuaj yeem txhim kho qhov ntsuas ntawm lub cev tiv thaiv kab mob ntawm broilers, thiab tuaj yeem hloov cov tshuaj tua kab mob hauv lub cev tiv thaiv kab mob thiab kev ua haujlwm antioxidant ntawm broilers.
2. Ua ib qho tshuaj tiv thaiv kab mob thiab tiv thaiv kab mob adjuvant
Raws li kev tiv thaiv kab mob, cov kab mob fungal polysaccharides tuaj yeem siv ua ke nrog cov tshuaj tiv thaiv txhawm rau txhim kho lub peev xwm ntawm cov tshuaj tiv thaiv kab mob, ua kom lub sijhawm ntev ntawm cov tshuaj tiv thaiv, thiab txo qhov ntau npaum li cas ntawm cov tshuaj tiv thaiv. Cov kev sim qhia tau hais tias cov kab mob fungal polysaccharides thiab astragalus polysaccharides tau ntxiv rau cov khoom noj sib cais. Cov fungal polysaccharides tuaj yeem ua tiav kev tiv thaiv ntau dua thiab khaws cov tshuaj tiv thaiv kab mob swine fever nyob rau hauv kev txiav txim. Lub compound Astragalus polysaccharide antibody qib kuj nce ntxiv tab sis tsis pom tseeb thiab tsis sib xws. Cov txiaj ntsig tau pom tias: cov kab mob Polysaccharides tuaj yeem nce qib ntawm cov tshuaj tiv thaiv kab mob tom qab txhaj tshuaj tiv thaiv swine fever zoo dua li Astragalus polysaccharides. Kev noj zaub mov huv-qib Beijing roj qaib nrog pub muaj Grifola frondosa polysaccharides qhia tias Grifola frondosa polysaccharides tuaj yeem nce qib ntawm AIV-H5 Ab thiab txhim kho phagocytes. Kev ua si, nce cov ntsiab lus ntawm T lymphocyte subgroups, txhim kho kev tsim khoom ntawm Beijing roj qaib, thiab txhawb kev tiv thaiv ntawm AIV-H5 subtype inactivated vaccine.
3. Ua tus txhawb nqa kev loj hlob rau tsiaj
Fungal polysaccharides siv nyob rau hauv cov tsiaj nyeg thiab nqaij qaib ntau lawm tuaj yeem txhawb txoj kev loj hlob ntawm cov nqaij qaib, txhim kho kev siv cov khoom noj, cov tsiaj ua tau zoo, qhov hnyav nce txhua hnub thiab muaj peev xwm tiv thaiv kev ntxhov siab. Xu Lingfeng et al. kawm txog cov teebmeem ntawm lentinan nyob rau hauv pob kws-soybean noj zaub mov basal noj ntawm kev ua tau zoo, as-ham digestibility thiab antioxidant muaj peev xwm ntawm piglets. Cov txiaj ntsig tau pom tias qhov sib ntxiv ntawm lentinan tuaj yeem txhim kho piglets ntawm 0 mus rau 14 hnub thiab 14 hnub. ～ 28 hnub thiab qhov nruab nrab qhov hnyav txhua hnub ntawm tag nrho lub sijhawm xeem; crude protein digestibility thiab crude fat digestibility kuj ho txhim kho; superoxide dismutase (SOD) kev ua haujlwm, glutathione peroxidase (GSH-Px) kev ua tau zoo dua qub
