I do calf vaccination while they drinking milk. Between the tail bone and the tail. Do you guy inject on the neck? Am I the strange one doing this way? Really curious. Please dont judge me. I know I am not perfect. haha.
I always do inject in a little upper side of neck when they are drinking but under the skin. You can also try it.
We try to inject in muscle and both places have muscle, normally in cows we inject between tail bone and tail, cause it is hard one neck when cow is standing on bail and cow have enough muscle on the tail but the calf may not have so I think the neck is the best place to vaccinate the calf🙂
