We employed a randomized block design with three replications. HybriForce-2410 presented the highest dry matter yield (28.87 t/ha) among the cultivars and the highest three-year average fresh matter yield (118.78 t/ha). The three-year average dry matter yield of Alfalfa-short (26.55 t/ha) and Shockwave BR (26.21 t/ha) were also significantly (p<0.05) higher than that of the other cultivars. The acid detergent fiber content of HybriForce-2410 was the lowest, although not significantly different from that of the other cultivars. Burgaltai had the lowest neutral detergent fiber content, whereas A Er Gang Jin had the highest. The crude protein (CP) content ranged from 16.90% to 21.33% at mowing during early flowering; Burgaltai had the highest CP among the cultivars. Digestibility differed significantly among the cultivars compared with other feed value items. Although Burgaltai presented the best feed value, HybriForce-2410 showed the best results for both productivity and feed value. http://pubs.sciepub.com/jfnr/10/3/5/jfnr-10-3-5.pdf alfalfa cultivar feed value forage pasture
