Yes, Alisa. BoSe should be given about 2 weeks prior to kidding. I also give BoSe to does earlier than that (or any time really) if I see their pasturns are dropped. The only does I gave this to that was not just prior to kidding was a dry 5yo and one other doe earlier in her pregnancy. I will repeat 2 weeks from kidding on this same doe. Typically, I follow From Birth to Kidding in GK101.
