My vet has said that also. He says it is rarely convenient but if you can give the Clostridials separately, you probably get a better immune response due to less interference.
So, now we should be running calves through the chute 3 times at weaning if no shots are given before?
The concern with vaccinating for multiple organisms at one time is overwhelming their immune system. For example, using a Clostridial (Blackleg 8 way), a Fetal Protection and pinkeye all at the same time. It becomes even more of a concern if the FP includes vibro and Leptospira (L5).
What I do is vaccinate all upcoming calves with Clostridial as a separate action at 3 months and 5 months (booster) of age.
Then later as the cows in your herd have been through previous vaccinations, there is less of an initial immune response. So not as much concern with overwhelming their immune system.
In everyday practice, most producers do not have the luxury of doing multiple vaccinations.
