what do goats eat? broomsedge

Broomsedge has value on our farm. As we gradually improve our pasture's fertility a small patch at at time, we still rely on our unimproved pastures during fall and winter. Our pastures contain a lot of Broomsedge. No one told the goats it was supposed to be poor forage. In late summer it begins producing its seed head. For about two weeks the goats will eat the tops of the Broomsedge trying to produce seed. Then the seed matures and they stop grazing the tops. We let it grow and do not cut it. Later in the fall when the frosts start to kill off the summer grasses and weeds, the bunches at the base of the plants are still green. It has been stock piled over the summer/fall and does not seem to be affected by the frost and remains green.
