A few cattleman were discussing vaccinating cows this morning. Seems there was some disagreement on if you should vaccinate cows in early pregnancy. A few said that vaccinating even with killed vaccine in early pregnancy (now through 90 days) might cause absorption of the embryo. Others said it wasn't the vaccination but the actual process of working the cattle through the pens/alley/chute, even if they were handled gently and easily.
So, what is everyone's opinion? They are vaccinated with Tri-View, vira-shield9VL5 + Harjo. Calves are vaccinated with Tri-View, Vira-shield 6, alpha-7, and one-shot.
The discussion started when one said they had preg checked and vaccinated in July, and then preg'd again in Oct and found 10-14% were either open or short bred and yet they were confirmed 30-70 days bred in July. (Ultrasounded both times)
