Estimation of Organic Matter Digestibility and Me Content in Ruminant Feeds from in Vitro Gas Production

چکیده
17-79 ABSTRACT Cumulative gas production from incubation of feedstuffs with rumen liquor or a fresh faecal suspension as inoculum in vitro together with crude nutrient composition can be used to predict organic matter digestibility and metabolizable energy content of ruminant feeds with high accuracy. In this study, prediction equations were derived for roughages using 110 samples with known in vivo digestibility. It can be demonstrated, that the accuracy of prediction of the gas production method is better compared with a pepsin-cellulase procedure and that the use of a faecal suspension as inoculum is a useful alternative when fresh rumen liquor is not available.

The purpose of this study was to determine the chemical composition and comparing the in vitro fermentation parameters of banana peel (BP) with wheat straw and alfalfa hay. Thereafter, BP was added at levels 0, 50, 100, 150 or 200 g/kg dry matter (DM) at the expense of dietary hay. Banana peel had higher crude protein (CP) content compared to wheat straw, but it was lower than alfalfa (P<0.05)....
