Summary
An autogenous, multivalent, adjuvanted bacterin for epididymitis was tested in flocks of 700 to 800 Suffolk X white-faced lambs. Long-term feeding of low dosages of antibiotics also was tested in the Suffolk flock. Both methods appeared to reduce the incidence of the disease. The incidence of clinical epididymitis and the number of positive culture results from clinically affected rams were significantly reduced.
