I use BoviShield5L5HB on my cows/heifers - in late Feb - 1 x a year. This would be the 4th BS5L5HB for the heifers prior to breeding (3 as calves).
With all the latest hoopla about MLV & timing before breeding, I have been real careful to get the shots done at least 30 days prior to breeding (closer to 45 if possible, which means some of my late calvers get the shot just prior to calving). I have never noticed this to be a problem on the heavy pregnants.
I breed for spring (well winter 1-1 thru 3-5) and for fall (9-1 thru 11-15?)
I am doing 100% AI again, so if I have a cow/heifer turn up open, I slide her into the fall group.
Under this program, I am vaccinating my pregnant falls when they are 3-4 months pregnant in Feb. Is this potentially harmful?? As long as they get the vaccination every 12 months, they are safe?
