Grazing has economic, health and animal welfare advantages when compared to breeding in total confinement. However, it is necessary to know and treat each plant species adequately to make the most of it. One of the most used pasture species for grazing is alfalfa, particularly in temperate climates.

Alfalfa has on average 8% pectins, 10% hemicellulose, 25% cellulose and between 7-8% lignin. Therefore, it ensures a rapid transit through the digestive tract, a significant supply of soluble fiber and high buffering capacity. It is a good source of macro minerals, especially calcium, chlorine and potassium. Its content in microminerals (manganese, zinc), vitamins (E, D, biotin and provitamin A), and pigments is also high.
