Polio and Cattle
Joplin Globe
STOCKTON, Mo. — When you hear about a cow or steer going down, what do you think of first?
Thanks to a lot of publicity, many people think of the worst-case scenario: Bovine Spongiform Encephalopathy (BSE), also known as mad cow disease.
That should be the last concern, said Dona Funk, University of Missouri Extension livestock specialist in Stockton.
First, think about polio, which is rare in cattle but could become more common as more livestock producers feed ethanol byproducts to cattle. The byproducts can have enough sulfur to cause polio in cattle.
Polio can be in an acute form that causes sudden death, or it can trigger staggering and blindness or cause animals to be down.
In addition to high sulfur, polio also can be caused by things such as lead toxicity, salt toxicity or thiamine deficiency.
The amount of sulfur and other chemicals in ethanol byproducts (dried distillers grain with solubles) varies among ethanol plants and among loads from the same plant. Funk said farmers feeding ethanol byproducts to livestock should seek to have each load they get tested each month.
