I use cattle Once in the nostrils. I get this from cattle supply places like PBS. I also give a shot made by Josh Newton.
I also give these things to the does so they make good colostrum for the fawns about forty days before they birth.
Guys correct me if I'm wrong but I think Josh is in PA. I don't have his number handy but I'm sure someone on here has it.
Josh has two types one for E-coli and a few other things and one for pneumonia.
My fawns have two issues when born they can get E-coli in spring and Fuso bacterium in late fall
I do give the does the ONCE in the nostrils which immune's them from pasturella
Those are the only disease shots I give.
