The absorption of volatile fatty acids from the rumen.
The fermentation of carbohydrates in the rumen of sheep is known to lead to the formation of large amounts of the lower fatty acids. The important part that these acids assume in the metabolism of ruminants has been remarked upon (Marston, 1939, 1946). While it is believed that acetic, propionic and butyric acids are the main fatty acid products of the fermentation, there is no certain knowledg...
متن کاملTHE ABSORPTION OF VOLATILE FATTY ACIDS FROM THE RUMEN II. THE INFLUENCE OF pH ON ABSORPTION
In a previous paper the relative rates of absorption of acetic acid and propionic acid through the rumen wall were discussed (Gray, 1947a). While the manuscript was being prepared, Danielli, Hitchcock, Marshall & Phillipson (1945) described a series of experiments from which it was evident that the lower homologues of the fatty acids are absorbed through the rumen wall at different rates when t...
متن کاملAbsorption of volatile fatty acids from the rumen of lactating dairy cows as influenced by volatile fatty acid concentration, pH and rumen liquid volume.
The effect of rumen liquid volume, pH and concentration of volatile fatty acids (VFA) on the rates of absorption of acetic, propionic and butyric acids from the rumen was examined in lactating dairy cows. Experimental solutions introduced into the emptied, washed rumen comprised two different volumes (10 or 30 l), four levels of pH (4.5, 5.4, 6.3, 7.2) and three levels of individual VFA concent...
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 کاملFermentation in the rumen of the sheep. II. The production and absorption of volatile fatty acids during the fermentation of wheaten hay and lucerne hay in the rumen.
Although the composition of the mixture of volatile fatty acids in the rumen of the sheep may be determined, it can throw no light on the composition of the mixture actually formed in the fermentation unless the relative rates of absorption of the acids are known, for it has been established that they are readily absorbed through the rumen wall into the blood stream (Barcroft, McAnally & Philli...
