Hello all.
This calving season we have had 2 premature calves out of 3 year olds. One was a second timer, looking back I think her first calf may have been a bit premature. The other aborted her first one early last year, but we kept to try again.
Both calves were around 30-40#. One is alive, but so far a dummy calf. The other was DOA with a bit of a malformed / undeveloped lower jaw.
I normally give 2 rounds of Vira Shield 6 + VL5 HB at weaning, but I had difficulty with this bunch. I do not think they ever received that vaccine. I am not great about annual boosters either.
Am I right in assuming this was not a coincidence and quite possible a vaccination issue? I know without substantial proof it is just conjecture, but I would like to hear the forum's experience / knowledge.
The rest of the herd is vaccinated and so far so good on calving. I have 7 live calves out of my non 3 years old (vaccinated) and likely 2 dead calves out of 3 year old group (non-vaccinated).
These two that have calved the premature calves will be culled and my remaining 3 year olds (all of 2 head) will be vaccinated at the earliest convenience to eliminate that variable.
