“…Moreover, CP has a positive correlation with relative forage value (RFV) and relative forage quality (RFQ) which can be used as an index to identify suitable forage for livestock (Undersander et al, 2011). Alfalfa is known as the 'Queen of Forage' as it has high protein content between 11.3-25.9% (Testa et al, 2011;Zhang et al, 2014;Avci et al, 2018;Cacan et al, 2018), high dry matter intake (DMI) (3.4-5.9%) (Basbag et al, 2009;Cacan et al, 2018) and highly digestible dry matter (DDM) (57.4-75.8%) (Basbag et al, 2009;Avci et al, 2018;Cacan et al, 2018). Several studies have found variations in alfalfa quality in different environments and varieties as, for example, in CP yield (2.1-5.8 ton/ha) (Kavut and Avcioglu, 2015;Cacan et al, 2018), in neutral detergent fiber (NDF) (20.3-49.6%) (Basbag et al, 2009;Kavut and Avcioglu, 2015;Avci et al, 2018;Cacan et al, 2018).…”
