Prebiotics mitigate in vitro sulfur-containing odour generation in caecal content of pigs
The objective of this study was to examine the effects and role of prebiotics, such as inulin, fructo-oligosaccharides (FOS) and galactooligosaccharides (GAS), to mitigate sulfur-containing odour gases, hydrogen sulfide (H2S) and methyl mercaptan (CH3SH) using pigs as <em>in vitro</em> s...
