[QUOTE="KNERSIE, post: 394915, member: 4353"] brucelloses will start to show as abortions at 5-7 months with retained placentas. Affected cows will most likely have swollen knees. If you or the vet suspects this the only way to be sure is to have all female bovines on the farm tested with a simple bloodtest. Usually only takes a few days to get the results back. All positives are culled, they get branded with a C on the left side of their neck (over here you must get a special permit from the REd Cross to transport them to the abbatoir) All clean female animals younger than 8 months gets vaccinated with CA strain 19 vaccine and all females older than 8 months with RB51. About 2-4% of bred cows that are vaccinated for the first time, might abort after being vaccinated so this is only done if there is already a problem. If you want to vaccinate anyway, do it about 3 weeks before the start of the breeding season. After that the herd must be retested every two months untill it has been clean for 6 months, then tested every 6 months untill its clean for two years. Then you'll get your brucella free status back. I sincerely hope for your part that brucella isn't the problem. [/QUOTE]
