| Popis: | The aim of this study was to better understand the ruminal solubility, bioavailability, effect on fermentation and microbiota of different sulfur (S) forms. In vitro fermentations with rumen fluid were conducted for 70hrs. Hay was incubated solely (CON), or with 0.5%DM of S, as: elemental sulfur (ES), Na2SO4 (NaS), (NH4)2SO4 (NHS) and MgSO4 (MgS). Fermentation was assessed by gas production (TGP) and dry-matter degradability (dDM%). Solubility and bioavailability were estimated by S concentration of the supernatant (SOL) and of bacteria (BACT). Microbial community was assessed by amplification of the 16SrRNA gene. NHS decreased (p |
