Influence de la caecotrophie sur la production, l'absorption et l'utilisation des acides organiques chez le lapin

Abstract

Summary. Effect of caecotrophy on the production, absorption and utilization of organic acids in the rabbit.The influence of caecotrophy on organic acid production and behaviour was studied for 4 days in rabbits with and without a collar preventing caecotrophy. Volatile

Effect of dietary soluble and insoluble fibre level, oligosaccharide supplementation and feed restriction on rabbit performance

“…It raises the questions whether part of the amount of TDF fermented before the ileum could be rather solubilized than fermented as hypothesized by Abad-Guamán et al (2015), and then overestimated, or whether the VFA could be absorbed faster in the ileum than in the caecum. Vernay (1986) reported that the ileal VFA concentration accounted for 7% of the caecal one, but the VFA concentration in the ileal vein was 27% of that in the caecal vein. The increase of soluble fibre decreased the molar proportion of butyrate in the caecum, that agrees with previous results (Ocasio-Vega et al, 2018b), although other studies reported no effect (Gómez-Conde et al, 2009;Trocino et al, 2013;Caisin et al, 2020), which in any case suggest that the positive effect of soluble fibre did not seem mediated by butyrate.…”
