| pubmed-article:1231619 | pubmed:abstractText | Volatile fatty acids (VFA) were measured by gas chromatography in the digestive material of Rabbits subjected to:--alimentary fast for 48 hours;--stercoral fast for 96 hours. A 48 hour alimentary fast caused a substantial drop in VFA in the digestive tract, butyric acid was the most affected, its concentration falling below that of propionate. Fasting for 48 hours did not cause a total cessation of fermentation. Stercoral fasting did not diminish the quantity of VFA in the digestive tract. VFA production was even augmented in the posterior parts (caecum and colon). | lld:pubmed |
