I have a field of haygrazer(sorghum/sudan hybrid) that I have had cattle grazing on. The cows had ate most of it but there was some still left. Today I shredded it all in anticipation of discing the field in a few weeks. Anyway in the meantime I was thinking of turning my horses out in the field as currently they are cooped up in a small corral and work has not given me much time to ride them. I know that the haygrazer is bad for them, but will it be ok now that it is shredded? I have a round bale of coastal that the horses have been eating and they will still have access to it.
