I hear what you're saying gcreekrch about the scour vaccine.  The heifers are due about April 20th and they got their first dose yesterday but I'm still up in the air with the cows.  Did your neighbor have them in one calving pasture or was he rotating his herd?  In my situation they get moved about once a week for the first 2 months.  I am nervous about not using it so maybe that's my gut telling me to.  One more time through the chute doesn't appeal to me either.
