<p>worldwide. It is one of the most important legumes, due to its ease of adaptation to different environments and its nutritional quality. Another important feature is its large biomass production, which allows forage to be stored for those times of the year when the climate conditions affect the forage supply. Another important factor that allows the choice of this forage is the ability it has to fix atmospheric nitrogen symbiotically, allowing lower production costs in terms of fertilization work, in addition to improving the chemical properties of the soil. On the other hand, it allows increasing the animal load capacity, improving the weight gain and milking productivity of the farms dedicated to livestock production. Due to these characteristics and thanks to the variety available, alfalfa allows production possibilities in different environments, adapting to an altitudinal range that ranges from 700 to 4000 meters above sea level, showing itself as a great forage alternative that it supplements deficiencies in biomass production and nutritional quality. Additionally, because it is a perennial crop, it prevents erosion and facilitates the control of some pests and diseases for those crops that will be established later. Set these features, it is necessary to update the characteristics and benefits of this legume, in order to be seen as forage with high productive and nutritional potential for the country's herds.&nbsp;</p>
