The minerals I feed are mix 50 / 50 with kelp meal and Hogger's supply Golden Blend Goat minerals. The minerals have a lot of selenium in it. My goats love kelp but I felt it did not have enough selenium. The hay in my area of north Idaho is selenium deficient so I mix the 2. I am a novice but read a lot and talked to experts. This is something I invented on my own. My boys turned out beautifully large and healthy for the Oberhasli breed. Hogger's also has a bolt on the wall mineral dispenser that works great.
