Extract

The association between rumen fermentation and gas production has long been known. The gas measuring technique has been widely used for evaluation of nutritive value of feeds. Gas measurement provides a useful data on digestion kinetics of both soluble and insoluble fractions of feedstuffs (Getachew et al., 1998). In the gas method, kinetics of fermentation can be studied on a single sample and therefore a relatively small amount of ample is required or a larger number of samples can be evaluated at time. When a feedstuff is incubated with buffered rumen fluid in vitro, the carbohydrates are fermented to short chain fatty acids (SCFA), gases (mainly CO2 and CH4) and microbial cells. Gas production is basically the result of fermentation of carbohydrates to acetate, propionate and butyrate (Beuvink and Spoelstra, 1992; Blu¨mmel and Ørskov, 1993). The purpose of this study was to valuate of nutritive value of grape marc (GM), tomato pomace (TP), grape pomace (GP) and raisin waste (RW) using gas production technique.
