 "Onobrychis" species are used as food plants by the caterpillars of some Lepidoptera species, such as the case-bearer moth "Coleophora colutella" (recorded on "O. saxatilis") and the Damon Blue ("Polyommatus damon") butterfly.Sainfoin provides a superb forage for grazing animals and voluntary intake of sainfoin by cattle and sheep is 20% higher than for grass.Unlike many other legumes, it is non-bloating and is known to have anthelmintic properties, so reducing the problems associated with livestock worms.
