Effects of high dietary fibre diets formulated from by-products from vegetable and agricultural industries on plasma metabolites in gestating sows.

摘要: The aim of the present study was to examine biochemical influence feeding high dietary fibre (DF) diets formulated from by-products vegetable and agricultural industries sows during early mid-gestation. effect frequency (once vs. twice daily) on diurnal plasma metabolites patterns also examined. included a total 48 gestating four blocks (12 in each block). were fed different containing varying levels starch (304-519 g/kg dry matter (DM)) DF (171-404 DM) but with equal amounts net energy. low-DF diet (control) based barley wheat, three high-DF by replacing wheat pectin residue, sugar beet pulp potato pulp, respectively. experimental design comprised two periods 4 weeks each. Half once daily at 08:00 h first period 15:00 second period, vice versa for other half sows. Plasma samples vena jugularis collected venipuncture 07:00, 09:00, 12:00 19:00 h. Feeding increased short-chain fatty acids (p = 0.02) non-esterified < 0.001). However, there no clear glucose insulin responses. A negative correlation between amount creatine (R2 1.00; effect: p suggested that concentrations an indicator level glucose-glycogen interchange. Furthermore, explorative approach using nuclear magnetic resonance spectroscopy-based metabonomics identified betaine 0.001), dimethyl sulfone (DMSO2; 0.001) scyllo-inositol as biomarkers by-products; residue related DMSO2, betaine, DMSO2 scyllo-inositol, scyllo-inositol. In conclusion, affected surprisingly few peripheral plasma. No effects found or judged minor metabolic changes.
