I raise holstein calves. About 20 to 30 on bottles at one time and keep them up to about 350 to 500 pounds. About 1 out of every 15 to 20 at about 2 to 3 months 0ld will get 1 ear sagging and tilt their head. I vaccinate with IBR nasalgen at 1 week, 2 doses of bovi-sheild about 1 month apart and P.H.M. Bac 1. It does not respond to any antibiotic and they will get over it in about amonths time. The vet thought it could be the mycoplasma bacteria causing it and didnt think there was any treatment yet. Any body ever have similar symptoms? Any ideas?
