Volatile fatty acids in the digestive tract of the fowl.
I. Examination of the digesta from all regions of the avian digestive tract showed that volatile fatty acids (VFAs) were present in greatest concentration in the caeca and that they comprised mainly acetic, propionic and butyric acids. 2. All droppings contained VFAs but they were present in highest concentration in those of caecal origin. Caecectomy was followed by a marked reduction in the to...
متن کاملThe Absorption of Soluble, Volatile Fatty Acids*
Experimental investigations show clearly that the absorption and metabolism of the short chain, water-soluble fatty acids differ in some way from those of the long chain fatty acids insoluble in water. Experiments by Lebedeff (1883), Leube (1895), Zunts (1901), and Eckstein (1929) show no evidence of the butyryl radical in the deposited fat when fed either as a fat or in the form of tributyrin....
متن کاملDiurnal variations in the concentrations of volatile fatty acids in the alimentary tracts of wild rabbits.
I . Wild rabbits were caught during both phases of the excretory cyclc and their gut contents were analysed for volatile fatty acids (VFA). 2. All rabbits were found to have high concentrations of VFA in the caecum and in the proximal colon. Acetic was the most abundant acid followed by n-butyric, then propionic. 3. VFA concentrations in the caecum and in the proximal colon of rabbits caught du...
متن کاملOrigin and utilization of volatile fatty acids in the rat.
The arteriovenous differences in the caecum of the rat have been compared for volatile fatty acids (VFA) and for electrolytes. Our results suggest the possibility of an exchange between VFA and chloride at the level of the caecal wall, rather than a net exchange between VFA and bicarbonate; however, the role of bicarbonate or Cl- at the cellular level is still unknown. Acetate uptake by the liv...
متن کاملBlood cultures evaluation by gas chromatography of volatile fatty acids.
The volatile fatty acid profiles were determined by a simple gas chromatographic method in 375 microbiologically positive and negative blood cultures. Aerobic bacteria yielded profiles with low content of acids, some of which were chromatographically negative. Anaerobic bacteria produced more acids and more distinctive profiles. The method makes it possible to confirm the microbiological findin...
