I started my fall breeding on Thanksgiving Day. Bred my sixth animal at 4 pm yesterday.
I performed my fall vaccinations in late October. I added a custom made pinkeye vaccine to my program. It includes several strains of Moraxella local to this area. The custom vaccine requires a booster after the initial inoculation. Rather than run the herd through for one shot, I have been giving the booster at the time of AI.
I was informed that is not a good practice. The immune response to the vaccine can potentially lower the conception rate.
It makes sense but would not seem to be that significant. Is there anything to support this?
