This is the vaccine that I picked up at Tractor Supply today is it right? Went in and asked the guy working the medicines for goat cdt vaccine and he said don't have anything for goats. I told the wife I was gonna get some penicillin anyway and when I looked in the cabinet there was this vaccine and it said10 cow doses or 25 sheep goat doses. I got it now I'm unsure if it's right. Says 25 doses so I plan to administer 2ccs each in the morning. How old should a goat be before it is vaccinated? I have them from 2 months to several years.
