have a set that I'm having a lot of trouble with they were vaccinated with pyramid5+preseponse and vision7 somnus with spur at branding June 18th and then rebostered on  Sept 23rd,cattle seem not to be getting better-not really aggressive at bunk, some are kind of just not interested in feed, hay or grass hay-on day 7 we gave are usually enforce and once internasal on day 3.My vet is kind of stump also-we are hoping its not bvd -have a few that are glazed over eyes and listless.
Thanks for any suggestions.They were 40 days weaned before I got them,but from day 1 they just never seem to go after any grass or hay in the bunk
