The CD/T vaccine at our feedstore comes in two varieties. One is marked for cattle - the other is marked for cattle and goats. Can someone tell me the difference? The bottles looks almost identical. Naturally - I made a mistake and shot the goats with the cattle variety. The goats are fine - but I was wondering what the difference is. Do I need to revaccinate?? Thanks in advance for any help. It is the Bar-Vac 7 vaccine manufactured by Boehringer Ingelheim.
