| Trichomonas |
A protozoan organism transmitted during breeding which causes failure of early pregnancy, an extended breeding season as females come back into heat, and, less commonly, abortion. Although a vaccine is available to raise the resistance to Trichomonas in the breeding herd, unless the condition has been positively diagnosed, the vaccine is not routinely recommended.
