Vaccination (2nd booster shots) went well with my bull except for the Pasturella pneumonia shot. Tried 3 times to get the 2 ml dose in the nostril and fail 3 times. What I had left was just enough to do the last 3 cows. He got his Cattlemaster Gold and Covexin 8 shots, so I just discharged him thru the side gate. Hopefully he will be ok with out it. Every time I tried to put the dose in , he would jerk his head. I may have gotten a little in but not much. With a lined chute he still climbed to the top of chute but couldn't stay there. He got the two shots though but not the nasal dose of Just Once Pm in.
