The simultaneous determination of short chain fatty acid, monosaccharides and ethanol in fermented liquid pig diets
نویسندگان
چکیده
A method is described for the simultaneous monitoring of four short chain fatty acids (SCFA) (lactic, acetic, propionic and butyric acid), two mono-saccarides (fructose and glucose) and ethanol in liquid feed for pigs and liquid feed fermented with lactic acid bacteria. The method involves a simple extraction technique, with average recoveries between 83 and 98%. Determination and quantification of each compound was achieved by isocratic, ion exclusion chromatography (IEC), at room temperature. Detection was by refractive index. © 2004 Elsevier B.V.

متن کاملFermented co-products and fermented compound diets for pigs: a review
This review deals with the properties of fermented diets and their effects on growth performance and gastrointestinal environment of pigs. In addition, some possible modes of action are hypothesized. Starch and sugar rich liquid co-products have a high potential for fermenting during storage. Soaking compound feed with water is another means of achieving a fermented diet. These diets are charac...

متن کاملContent of short-chain fatty acids in the hindgut of rats fed processed bean (Phaseolus vulgaris) flours varying in distribution and content of indigestible carbohydrates.
Red kidney beans (Phaseolus vulgaris) processed to differ in distribution and content of indigestible carbohydrates were used to study hindgut fermentability and production of short-chain fatty acids (SCFA). Bean flours with low or high content of resistant starch (RS), mainly raw and physically-inaccessible starch, were obtained by milling the beans before or after boiling. Flours containing r...
