Goats can be picky eaters, and they may not immediately accept new feeds. Any feed changes should be made gradually to avoid upsetting the rumen microbes. Feeding very high levels of grain can also upset the rumen. Grain should never be more than 50% of the total diet, except for heavily-producing dairy goats.
