The seeding year’s growth of alfalfa, ladino clover and birdsfoot trefoil has been shown to be essentially free of estrogenic activity. Uninterrupted second-year growth of alfalfa and ladino clover displays relatively high activity in the spring, little or none in mid-summer, and an intermediate level of activity in the autumn. Sequential cutting leads to a modification of this pattern. The presence of slight activity in birdsfoot trefoil and the absence of activity in orchard grass has been demonstrated.
