Extract

The in situ technique forms the basis of many feed evaluation systems for ruminants. Although this method is widely used, the NBT is very laborious, time-consuming, and incubations and analyses of the feed residues often last several weeks. Therefore, several other techniques have been investigated to measure and predict ruminal degradation of various chemical components of feedstuffs. The aim of this study is to investigate the possibilities of estimating in situ degradation characteristics of DM, CP, ADF and NDF in several feedstuffs by gas production characteristics and chemical composition.
