Any vaccination and treatment history? If yes, please detail specifically, what, when and how.
The baby calves should have a short period of immunity from colostrum but 2 months old and I've seen pinkeye in the slow do-ers at surprisingly young age.
There are 2 bacteria species ( M. Bovis and M. Boviculli) and multiple strains in each that cause pinkeye. The second was once named as the cause of winter pinkeye. Cold weather does not stop it and I'd think southern Kansas could harbor both due to temperate conditions.
You asked more questions that I unfortunately answered with more questions. Sorry
I echo Doug with vaccination history? I’m 30 miles from Doug, we were getting it in winter as bad with weaned calves. Tried extra A or E, which ever suppose to help, can’t remember off hand. It didn’t help. We finally got ahead of it by giving both Bovis and Boviculli twice a year to cows and calves, we usually feed and graze to 850#. We have almost went to zero summer and winter. |
