[QUOTE="Jeanne - Simme Valley, post: 1740235, member: 968"] I always use MLV - but have always been careful to inject at least 30 days prior to start breeding. But, that was always difficult, so now I vaccinate my spring calvers MLV in the fall and fall calvers in the spring. As long as they receive the vaccine within 12 months, you can vaccinate while they are pregnant. And, actually, the cows should have better immunities in their colostrum this way. My conception rate has been great. In order to get into this pattern, the cows got vaccinated twice in the same year (spring and fall - or fall and spring) [/QUOTE]
