Cowherd has been on FP-5 for years. My buyers won't give a premium for vaccinated calves as yet so calves only get Vision 8-S at branding. The two years we tried a pasturella vaccine we had more "summer pnuemonia" than all the other years combined.

Any calves retained after weaning are boostered with Vision 8-S and started on FP-5.

We all do what works best for us.

Texan, you won't regret adding the somnus, IMO it is a good vaccine.
