I use a mix that includes red cell for my pregnant does. I had several does that came to me with deficiencies and I know the soil in our area has certain things it lacks so local hay doesn't fill everything in, and i don't grain them for the last two months or so (and they don't seem to be eating enough of their minerals to make up for what they need). I mix a little iodized salt (one of my does came to me with pretty severe iodine deficiency) with one part red cell, one part water, two parts molasses and if I know they are lacking something specific I get some vitamins and crush them to a fine power and mix that in (most recently B complex). I dose them with it every day but only like 3 or 4 CC's orally. They love the stuff, lick it up like candy. Probably because with all that molasses it IS like candy. I also give it to anyone who seems stressed or otherwise not at 100%. Not sure it helps but it seems to make them feel like they are getting spoiled and perks them up.
