What causes stiff legs in cattle?
The most common ailment noticed by cattlemen in selenium deficient cattle is white muscle disease. This disease causes calves to be stiff and have damage to their muscles especially in the hind legs. In addition, sudden death can result from cardiac failure in calves deficient in selenium.
How is bovine ephemeral fever spread?
Three day sickness, or bovine ephemeral fever (BEF), is a viral disease of cattle that is spread by mosquitoes and biting midges. It occurs in northern Australia and along the eastern seaboard south to the NSW-VIC border.
What are the signs of brucellosis in cattle?

Not all infected cows abort, but those that do usually abort between the fifth and seventh month of pregnancy.
What are the symptoms of leptospirosis in cattle?

Inapparent infections can develop in Cape buffalo, hartebeest, waterbuck, wildebeest, deer, and possibly goats, sheep, and gazelles.
How do you test for bovine ephemeral fever?
Isolated viruses are identified by PCR and sequencing, neutralization tests using specific BEFV antisera, and ELISA using specific monoclonal antibodies. Complete rest is the most effective treatment for bovine ephemeral fever, and recovering animals should not be stressed or worked because relapse is likely.
How do you treat ephemeral fever in cows?
