Kuti tiongorore mhedzisiro yekuwedzera triglyceride mukudya pakugadzirwa kwemapuroteni ebhakitiriya emudumbu uye hunhu hwekuvirisa kwenhunzvi diki dzemuswe dzakura, kuyedza kuviri kwakaitwa mu vitro nemu vivo.

Kuongororwa kwemuviri: kudya kwekutanga (kwakavakirwa pachinhu chakaoma) chine huwandu hwe triglyceride hwe 0, 2, 4, 6 uye 8g / kg kwakashandiswa se substrate, uye muto werumen wenhunzvi dzehurume dzemuswe mudiki wakaiswa, ndokuiswa pa39 ℃ kwemaawa makumi mana nemasere mumuviri muropa.

Kuongororwa kwemuviri: makwai makuru makumi mana nemashanu akakamurwa zvisina tsarukano kuita mapoka mashanu zvichienderana nehuremu hwawo hwepakutanga (55 ± 5 kg).Glyceryl tributylateye 0, 2, 4, 6 uye 8 g/kg (zvichienderana nezvinhu zvakaoma) yakawedzerwa pakudya kwekutanga, uye mvura yerumen neweti zvakaunganidzwa kwemazuva gumi nemasere.

Mhedzisiro yeMuedzo

1). Mhedzisiro pa pH uye kuunganidzwa kwemafuta ane acid yakawanda

Zvakabuda zvakaratidza kuti pH kukosha kwenzvimbo yekumera kwakadzikira zvakananga uye kuwanda kwe total volatile fatty acids (TVFA), acetic acid, butyric acid uye branched chain volatile fatty acids (BCVFA) kwakawedzera zvakananga kanatributyl glycerideyakawedzerwa kune substrate. Mhedzisiro yebvunzo ye in vivo yakaratidza kuti dry matter intake (DMI) uye pH value yakaderera, uye kuwanda kweTVFA, acetic acid, propionic acid, butyric acid neBCVFA kwakawedzera zvakananga nekuwedzera kwetributyl glyceride.Mhedzisiro yebvunzo ye in vivo yakaratidza kuti dry matter intake (DMI) uye pH value yakaderera, uye kuwanda kweTVFA, acetic acid, propionic acid, butyric acid neBCVFA kwakawedzera zvakananga nekuwedzera kwetributyl glyceride.

Mhedzisiro yebvunzo ye in vivo yakaratidza kuti dry matter intake (DMI) uye pH value yakaderera, uye kuwanda kweTVFA, acetic acid, propionic acid, butyric acid neBCVFA kwakawedzera zvakananga nekuwedzera kwetributyl glyceride.

2). Kuvandudza mwero wekuora kwezvinovaka muviri

Mwero wekuderera kweDM, CP, NDF uye ADF wakawedzera zvakananga apotributyl glycerideyakawedzerwa kune substrate in vitro.

3). Kuvandudza mashandiro e enzyme inoparadza cellulose

Kuwedzerwa kwetributyrinKuongororwa kwe "in vitro" kwakawedzera mashandiro e "xylanase", "carboxymethyl cellulase" uye "microcrystalline cellulase". Kuongororwa kwe "in vivo" kwakaratidza kuti triglyceride yakawedzera mashandiro e "xylanase" uye "carboxymethyl cellulase".

4). Kuvandudza kugadzirwa kwemapuroteni ehutachiona

Kuongororwa kwemuviri kwakaratidza kutitributyrinkuwedzera kwakarongeka huwandu hweallantoin, uric acid uye purine inonyudzwa muweti, uye kuwedzera kugadzirwa kwenitrogen yerumen microbial.

Mhedziso

TributyrinYakavandudza kugadzirwa kwepuroteni yerumen microbial, huwandu hwemafuta anoputika uye mashandiro emaenzymes anoparadza cellulose, uye yakakurudzira kudzikira nekushandiswa kwemafuta akaoma, mapuroteni asina kuchena, fiber yedetergent isina kusimba uye fiber yedetergent ine acid mukudya.

Zvinoratidza kuti triglyceride ine mhedzisiro yakanaka pakubereka nekuvirisa kwepuroteni yerumen microbial, uye inogona kuva nemhedzisiro yakanaka pakubudirira kwekugadzirwa kwemakwai akura.
