Going to pick up some 3 month old goats soon they are Nigerian dwarf doelings. They haven't been on pasture before and have been feed some hay and mostly goat chow. I want to pasture them (I will do this slowly to prevent gas or bloat issues) and they will have free choice of good grassy alfalfa mix hay. I had planned on feeding grain when needed (growing, pregnant, nursing, and in very cold weather) but what is goat grain. I was under the impression that goat chow had grain in it as well as supplements and a fiber of some kind. So is there a straight up just grain mix that you feed to goats? I've read up to 3 cups of grain for a full size goat kid, is this grains or goat chow measurements? I guess I'm confused about what grain should I feed a goat kid of this age and breed. None of the books or info I can find are very specific regarding this issue. Maybe this is a dumb thing to ask but I want to make sure I understand everything before I get the goats here. Thanks
