| I am quite sure that it makes a difference, esp. since both are from Merck, trying to figure out what to use to cover all the bases without having to run calves thru the chute more then 2x makes it tricky, also do not want to wait 6 weeks to booster as it can darn cold up here when you get out to the last week of Nov./first week of December and I may want to sell shortly after so also want them boostered at least 2-3 weeks before they hit the sale barn to challenge the vaccines. | |
