Thanks Jena,
I tried feeding it free choice to her but she inhaled some and I decided that wasn't a smart plan, so I've mixed it in with the coarse 14 feed which, because of the molasses, prevents the powder from being inhaled. Perhaps it makes no difference in the big scheme of things but it makes me feel better.
I like the idea of using a food supplement that cuts down on fly larvae so if you can remember the name of that stuff please add a post or perhaps a pm if this thread drops into the archives first. I agree... the salt block, though amusing to my steer, is meaningless to this heifer. It doesn't get rained on since I keep it in the stall, but she's been ignoring it completely. I'm really looking forward to spring since I fertilized and seeded the brand new pasture area with a Timothy/Clover mix last fall. I'm psyched!!! Come on Spring!!!
