So we decided to order the gel instead of BoSe for now. It says that it should be the sole source of selenium. But there is selenium in our feed. I'm sure BoSe might have the same warning? I'm a dummy, but can't remember if selenium is in the loose mineral, and if so, how much. Since they get selenium in the grain and most likely in the mineral, should I just give them a smaller dose? I am wanting to use this for newborns and does right after kidding, so this issue would be more for the does safety since the kids obviously don't eat grain when they are born. And reading the info on it at Jeffers website, I didn't see anything pertaining to how much I should give, just this: 80 ml dial-a-dose tube contains (16) 5 ml doses. What do you give the kids, and what to give the does? Sorry for all the questions, I was prepared to get BoSe, but hubby wants to try this and see if we like it. Also if you have used the gel you can give a yay or nay on what you thought about it Thanks!
