Extract

Public aversion to animal experimentation demands the replacement of typically expensive, laborious and lengthy in vivo forage evaluation techniques with non-invasive, laboratory-based techniques. This study aimed to assess the suitability of three less animal-dependent techniques (in vitro digestibility (Tilley and Terry, 1963), in situ degradability (Ørskov and McDonald, 1979) and gas production (Theodorou et al., 1994)) for predicting the in vivo digestibility of whole crop wheat (WCW). The study forms part of an on-going MAFF LINK project that aims to develop equations for the laboratory-based prediction of the nutritive value of WCW.
