Txhawm rau soj ntsuam cov txiaj ntsig ntawm kev ntxiv triglyceride rau kev noj zaub mov ntawm rumen microbial protein ntau lawm thiab fermentation yam ntxwv ntawm cov neeg laus me me, ob qhov kev sim tau ua hauv vitro thiab hauv vivo.

Hauv vitro xeem: cov khoom noj basal (raws li cov khoom qhuav) nrog triglyceride ntau ntawm 0, 2, 4, 6 thiab 8g / kg tau siv los ua cov substrate, thiab cov kua txiv hmab txiv ntoo ntawm Cov Neeg Laus Me Me Tailed ewes tau ntxiv, thiab incubated ntawm 39 ℃ rau 48h hauv vitro.

Hauv vivo xeem: 45 tus neeg laus ewes tau muab faib ua 5 pawg raws li lawv qhov hnyav thawj zaug (55 ± 5 kg).Glyceryl tributylatentawm 0, 2, 4, 6 thiab 8 g / kg (raws li cov khoom qhuav) tau ntxiv rau cov zaub mov yooj yim, thiab cov kua dej rumen thiab zis tau sau rau 18 hnub.

Kev Xeem

1).Qhov cuam tshuam rau pH tus nqi thiab qhov tsis haum ntawm fatty acid concentration

Cov txiaj ntsig tau pom tias pH tus nqi ntawm cov kab lis kev cai nruab nrab txo qis thiab cov concentration ntawm tag nrho cov volatile fatty acids (TVFA), acetic acid, butyric acid thiab branched chain volatile fatty acids (BCVFA) nce linearly thaumtributyl glyceridestau ntxiv rau hauv lub substrate.Cov txiaj ntsig ntawm qhov kev ntsuam xyuas hauv vivo pom tias cov khoom qhuav kom tsawg (DMI) thiab pH tus nqi txo, thiab cov concentrations ntawm TVFA, acetic acid, propionic acid, butyric acid thiab BCVFA nce linearly nrog ntxiv ntawmtributyl glycerides.Cov txiaj ntsig ntawm kev kuaj hauv vivo pom tias cov khoom qhuav kom tsawg (DMI) thiab pH tus nqi txo, thiab cov concentrations ntawm TVFA, acetic acid, propionic acid, butyric acid thiab BCVFA nce linearly nrog ntxiv ntawm tributyl glyceride.

Cov txiaj ntsig ntawm kev kuaj hauv vivo tau pom tias cov khoom qhuav kom tsawg (DMI) thiab pH tus nqi txo qis, thiab cov ntsiab lus ntawm TVFA, acetic acid, propionic acid, butyric acid thiab BCVFA nce linearly nrog ntxiv ntawmtributyl glycerides.

2).Txhim kho tus nqi degradation ntawm cov as-ham

Qhov pom meej degradation tus nqi ntawm DM, CP, NDF thiab ADF nce linearly thaumtributyl glyceridestau ntxiv rau substrate hauv vitro.

3).Txhim kho cov haujlwm ntawm cellulose degrading enzyme

Qhov ntxiv ntawmtributyrinHauv vitro linearly nce cov haujlwm ntawm xylanase, carboxymethyl cellulase thiab microcrystalline cellulase.Hauv vivo kev sim pom tias triglyceride linearly nce cov haujlwm ntawm xylanase thiab carboxymethyl cellulase.

4).Txhim kho microbial protein ntau lawm

Hauv vivo xeem tau pom tiastributyrinlinearly nce tus nqi txhua hnub ntawm allantoin, uric acid thiab absorbed microbial purine hauv cov zis, thiab nce cov synthesis ntawm rumen microbial nitrogen.

Xaus

Tributyrintxhim kho cov synthesis ntawm rumen microbial protein, cov ntsiab lus ntawm tag nrho cov volatile fatty acids thiab cov kev ua ntawm cellulose degrading enzymes, thiab txhawb kev degradation thiab siv cov khoom qhuav, crude protein, nruab nrab detergent fiber thiab acid detergent fiber nyob rau hauv kev noj haus.

Nws qhia tias triglyceride muaj txiaj ntsig zoo rau kev tawm los thiab fermentation ntawm rumen microbial protein, thiab tej zaum yuav muaj kev cuam tshuam zoo rau kev tsim khoom ntawm cov neeg laus ewes.
