When to stop grain

[deschutes dawn]

I have been feeding good quality grass hay with occasional stemmy alfalfa free choice for the youngsters with free choice minerals designed specically for this area. They are doing well in the cold and my 8 mo. old saanen/alpine is already as tall as the saanen does. My adult packers are doing well on just the grass hay too. They get a treat of cob or alfalfa when I go out to clean their area. I'm lucky my horses don't mind trompled hay and I throw them the waste from the goats, so no waste at all. My vet is adamantly against any grain for wethers so I try to keep it minimal.
