Subclinical genital infection of rams with Brucella ovis

Magyar Allatorvosok Lapja 43(11): 655-662

Subclinical genital infection of rams with Brucella ovis

Over a 3.5-year period up to January 1988, strains of B. ovis were isolated from 240 (19.4%) of 1234 individual sperm samples taken from rams in 37 of 46 breeding stocks, and from 12 (3.7%) of 327 samples from ram hoggs in 4 of 9 stocks. The incidence within stocks varied from 2.2-36.3%.
