Early detection and treatment of vesicular adenitis in bulls

The proportion of bulls with vesiculitis was 4.4% (97/2207). At the pre-sale semen test the number of bulls with vesiculitis had decreased to 1.3% (29/2207); however, seven of these were new cases that developed after the first examination. Therefore, there was a recovery rate of 75/97 (77.3%) in the original group of bulls positive for vesiculitis. At the pre-sale test, there was no difference in the proportion of bulls with enlarged glands in the positive treated group (15/66) versus the positive untreated group (7/31) and no difference in the proportion of bulls with leukocytes or pus in their semen samples. The results of this experiment did not indicate any advantage in detection and treatment of vesiculitis before a year on age due to a high rate of spontaneous recovery.
