Bakeng sa ho lekola phello ea ho kenyelletsa triglyceride lijong mabapi le tlhahiso ea protheine ea rumen microbial le litšobotsi tsa ho belisoa ha linku tse kholo tsa mohatla, liteko tse peli li entsoe ka in vitro le in vivo.

Teko ea in vitro: lijo tsa basal (tse thehiloeng holim'a taba e omileng) tse nang le likhahla tsa triglyceride tsa 0, 2, 4, 6 le 8g / kg li ile tsa sebelisoa e le substrate, 'me lero la rumen la tse tšehali tse kholo tse nyenyane tse Tailed li ile tsa kenngoa,' me tsa kenngoa ka 39 ℃ bakeng sa 48h in vitro.

Teko ea in vivo: tse 45 tse kholo li ile tsa aroloa ka lihlopha tse 5 ho latela boima ba tsona ba pele (55 ± 5 kg).Glyceryl tributylateya 0, 2, 4, 6 le 8 g/kg (e thehilweng hodima ntho e omeletseng) e ile ya ekeletswa dijong tsa motheo, mme lero la rumen le moroto di ile tsa bokellwa ka matsatsi a 18.

Sephetho sa Tlhahlobo

1).Phello ho boleng ba pH le ho tsepama ha mafura a mafura

Liphello li bonts'a hore boleng ba pH ba setso bo fokotsehile ka mokhoa o tšoanang 'me likhakanyo tsa mafura a mafura a mangata (TVFA), acetic acid, butyric acid le branched chain volatile fatty acids (BCVFA) li eketsehile ka mokhoa o tšoanang hatributyl glycerideLiphello tsa tlhahlobo ea in vivo li bontšitse hore ho kenngoa ha lintho tse omileng (DMI) le pH boleng li fokotsehile, 'me likhahla tsa TVFA, acetic acid, propionic acid, butyric acid le BCVFA li eketsehile ka mokhoa o tšoanang letributyl glyceride.Liphello tsa tlhahlobo ea in vivo li bontšitse hore ho kenngoa ha taba e omileng (DMI) le pH ea boleng e fokotsehile, 'me likhahla tsa TVFA, acetic acid, propionic acid, butyric acid le BCVFA li eketsehile ka mokhoa o tšoanang ka ho eketsoa ha tributyl glyceride.

Liphetho tsa tlhahlobo ea in vivo li bonts'itse hore ho kenngoa ha lintho tse omeletseng (DMI) le pH boleng li fokotsehile, mme likhakanyo tsa TVFA, acetic acid, propionic acid, butyric acid le BCVFA li eketsehile ka mokhoa o ts'oanang.tributyl glyceride.

2).Ntlafatsa sekhahla sa ho senyeha ha limatlafatsi

Sekhahla se bonahalang sa ho theoloa ha DM, CP, NDF le ADF se eketsehile ka ho lekana hatributyl glyceridee ile ea eketsoa ho substrate in vitro.

3).Ntlafatsa ts'ebetso ea enzyme e senyang cellulose

Keketso eatributyrinin vitro ka tsela e tšoanang e ekelitse mesebetsi ea xylanase, carboxymethyl cellulase le microcrystalline cellulase.Liteko tsa vivo li bonts'itse hore triglyceride e ekelitse ts'ebetso ea xylanase le carboxymethyl cellulase.

4).Ntlafatsa tlhahiso ea protheine ea likokoana-hloko

Liteko tsa in vivo li bontšitse seotributyrinka tsela e tšoanang e ile ea eketsa palo ea letsatsi le letsatsi ea allantoin, uric acid le ho monya microbial purine morotong, le ho eketsa motsoako oa rumen microbial nitrogen.

Qetello

Tributyrine ntlafalitse ho qaptjoa ha rumen microbial protein, litaba tsa kakaretso ea li-voltatile fatty acids le tšebetso ea li-enzyme tse senyang selulose, le ho khothalletsa ho senyeha le ho sebelisoa ha lintho tse omileng, protheine e tala, fiber e sa jeleng paate le fiber e hloekisang asiti lijong.

E bontša hore triglyceride e na le phello e ntle ho kotulong le ho belisoa ha rumen microbial protein, 'me e ka ba le phello e ntle ts'ebetsong ea tlhahiso ea linku tse kholo.
