The Grazemore decision support system to predict the quality of pasture grass in dairy production
Introduction Grazemore DSS is a decision support system ( DSS) developed to improve the use of grazed grass in dairy production in Europe ( Hetta et al.,2005).The software consists of a herbage growth model ( HGM) and an herbage intake model ( HIM).The HGM predicts daily herbage growth (Barrett,Laidlaw & Mayne,2004) and thereafter the DSS predicts crude protein (CP) and organic matter digestibility ( OMD) of the herbage.Based on the information on herbage mass and quality of the grass the HIM predicts milk production,herbage intake as daily averages for the herd during the residence time in each paddock (Delagarde et al.,2004).The aim of this study was to examine if the predictions of the herbage quality of the software Grazemore DSS gives a reliable ground for grass based dairy production in the north of Scandinavia.
