One of our local cow vets suggests vaccinating at day old. Another suggests waiting until 2 months of age to vaccinate. The reason he suggests to wait is that the maternal antibodies in a calf younger than two months will not allow the vaccine to produce immunity in the calf. The way I see it, is it's okay to wait til they are two months old as long as you don't lose a calf before then, which I know has happened in the past before two months. I suppose vets are like cow farmers and all have their own opinion about most every thing.
So, at what age do you "blackleg" your calves, and have you ever lost a calf to blackleg when vaccinating the way you currently do?
Thanks,
