I know that generally goats should be fed at a 2:1 ratio, calcium to phosphorus. Most advice suggests alfalfa hay and a commercial dairy ration for the best milk production. Alfalfa Hay is high in calcium. All commercial dairy rations are balanced for calcium to phosphorus 2:1. So, wouldn't this scenario overload the doe with calcium, making it difficult for her to use said calcium because she needs the phosphorus in a proper proportion in order to make the calcium available to her? I can see how the commercial ration would make a lot of sense when feeding grass hay, or even with limited alfalfa. But if the does are fed alfalfa primarily, and grass at maybe only 20%, wouldn't a ration without supplemental calcium make more sense, say COB?
