Abstract :Cultivated forage species may have higher nutrients contents insert ignore into journalissuearticles values(NC); and forage quality indicators insert ignore into journalissuearticles values(FQI); than their wild relatives. Nine forage samples collected five times from a mixed rangeland and an experimental field during two consecutive years was analysed for ash, crude protein insert ignore into journalissuearticles values(CP);, ether extract insert ignore into journalissuearticles values(EE); and neutral detergent insert ignore into journalissuearticles values(NDF); and acid detergent insert ignore into journalissuearticles values(ADF); fibres. Then, their FQI such as digestible dry matter insert ignore into journalissuearticles values(DDM);, dry matter intake insert ignore into journalissuearticles values(DMI);, metabolizable energy insert ignore into journalissuearticles values(ME); and relative forage quality insert ignore into journalissuearticles values(RFQ); were calculated. Data were performed in a linear model with fixed effects insert ignore into journalissuearticles values(forage plant type [PT] and species [PS]); to NC and FQI, and subjected to hierarchical two-way clustering analysis. Cultivated and wilds relatives varied in CP insert ignore into journalissuearticles values(12.0-18.9% and 8.8-23.3%);, ADF insert ignore into journalissuearticles values(20.9-33.1% and 39.3-73.5%); and NDF insert ignore into journalissuearticles values(37.2-61.6% and 26.7-46.1%); contents and ME insert ignore into journalissuearticles values(8.7-9.7 MJ kg-1 DM and 7.0-9.6 MJ kg-1 DM); and RFQ insert ignore into journalissuearticles values(98.8-186.7 and 74.6-161.7); values. There were interactions between PT and PS for all NC and FQI, except for CP and EE contents. In general, the CP, EE, ADF, ME and RFQ of cultivars were higher, whereas NDF was lower than those of the wilds. The most notable differences insert ignore into journalissuearticles values(NDF, ADF and RFQ); between the PT represented the differences in nutritional traits based on the clustering analysis. The cultivated and wilds relatives are comprised of NC and FQI that respond differently under same circumstances.
