Hei aromatawai i te pānga o te tāpiri triglyceride ki te kai ki te whakaputa pūmua moroiti rumen me ngā āhuatanga whakapūmau o ngā hipi uha pakeke iti, e rua ngā whakamātautau i whakahaerehia i roto i te vitro me te in vivo.

Whakamātautau in vitro: ko te kai taketake (i runga i te mea maroke) me ngā kukū triglyceride o te 0, 2, 4, 6 me te 8g/kg i whakamahia hei tūāpapa, ā, i tāpirihia te wai rumen o ngā hipi uha pakeke hiku iti, ā, i whaowhia ki te 39 ℃ mō te 48h in vitro.

Whakamātautau in vivo: I wehea matapōkeretia ngā hipi uha pakeke e 45 ki ngā rōpū e 5 i runga i tō rātou taumaha tīmatanga (55 ± 5 kg).Glyceryl tributylateI tāpirihia he 0, 2, 4, 6 me te 8 karamu/kg (i runga i te mea maroke) ki te kai taketake, ā, i kohia te wai rumen me te mimi mō ngā rā 18.

Hua Whakamātautau

1). Pānga ki te uara pH me te kukū waikawa ngako pūngāwerewere

I whakaatuhia e ngā hua he hekenga rārangi te uara pH o te reo ahurea, ā, he pikinga rārangi hoki ngā kukū o ngā waikawa ngako pūngāwerewere katoa (TVFA), te waikawa acetic, te waikawa butyric me ngā waikawa ngako pūngāwerewere mekameka manga (BCVFA) inatributyl glyceridei tāpirihia ki te papa. I whakaatuhia e ngā hua o te whakamātautau in vivo kua heke te kai maroke (DMI) me te uara pH, ā, kua piki haere ngā kukū o te TVFA, te waikawa acetic, te waikawa propionic, te waikawa butyric me te BCVFA i te tāpiritanga otributyl glycerideI whakaatuhia e ngā hua o te whakamātautau in vivo kua heke te kai maroke (DMI) me te uara pH, ā, kua piki haere ngā kukū o te TVFA, te waikawa acetic, te waikawa propionic, te waikawa butyric me te BCVFA i te tāpiritanga o te tributyl glyceride.

I whakaatuhia e ngā hua o te whakamātautau in vivo kua heke te kai maroke (DMI) me te uara pH, ā, kua piki haere ngā kukū o te TVFA, te waikawa acetic, te waikawa propionic, te waikawa butyric me te BCVFA i te tāpiritanga otributyl glyceride.

2). Whakapai ake i te tere pirau o ngā matūkai

I piki haere te tere o te whakahekenga kitea o DM, CP, NDF me ADF i te wātributyl glyceridei tāpirihia ki te papa i roto i te vitro.

3). Whakapai ake i te mahi a te whākōkī whakaiti cellulose

Te tāpiritanga otiritiririnI roto i te vitro i whakapiki ake i ngā mahi a te xylanase, te carboxymethyl cellulase me te microcrystalline cellulase i runga i te rārangi. I whakaatuhia e ngā whakamātautau in vivo i whakapiki ake te triglyceride i ngā mahi a te xylanase me te carboxymethyl cellulase i runga i te rārangi.

4). Whakapai ake i te whakaputanga pūmua moroiti

I whakaatuhia e ngā whakamātautau in vivotiritiririni whakapiki ake i te nui o te allantoin, te waikawa uric me te purine microbial i roto i te mimi i ia rā, ā, i whakapiki ake i te hanganga o te hauota microbial rumen.

Whakamutunga

Tributyrini whakapai ake i te hanganga o te pūmua moroiti rumen, te ihirangi o ngā waikawa ngako pūngoikore katoa me te mahi a ngā whākōkī whakaiti cellulose, ā, i whakatairanga i te whakaiti me te whakamahinga o te mea maroke, te pūmua mata, te muka hopi horoi kūpapa me te muka hopi horoi waikawa i roto i te kai.

E tohu ana tēnei he pānga pai tō te triglyceride ki te hua me te whakapūkara o te pūmua moroiti rumen, ā, tera pea he pānga pai ki te mahi whakaputa o ngā hipi uha pakeke.
