Alright, so I know both are selenium and Vitamin E, but I've heard the you can only use Bo-Se on the kids. We live in a small town so all we could get in was Mu-Se for cattle. Will this make a difference? We used it on our kids and they are 5 weeks old now and doing great. We live in a selenium deficient area so we have been giving all our kids a 1/4cc at birth.
