Important role of alfalfa in development of animal husbandry, is based on high potential for production of biomass. Reaching of high green (over 80 t ha-1) and dry matter yield (approx. 20 t ha-1) with low investment during all period of utilization makes alfalfa production very economical. Divergent selection materials were used to create high productive domestic alfalfa cultivars with excellent field persistence, which is important factor for high and stable yield during entire exploitation period. On the other hand, alfalfa is a rich source of crude protein with excellent digestibility. Proteins from alfalfa herbage are the cheapest source of protein in animal feed. Content of crude protein strongly depend on development stage of plant material and can be 200 to 240 g kg-1 DM, while crude protein yield can be over 3.5 t ha-1. Besides that, alfalfa herbage had a high content of macro and micro element, which are so important for animal health. It is usually grown in pure stand, although it's a good component of grass-legumes mixtures. Alfalfa biomass can be used in several ways, usually as hay, but also as high quality silages, haylages, dehydrated in form of briquettes or by grazing. Symbiotic N2 fixation gives alfalfa not just economical, but very high ecological importance, too. It's a reason why alfalfa, besides important role in conventional husbandry is getting great role in sustainable agriculture and organic production. All those characteristics confirm, that alfalfa is a really 'queen' of forages.
