Researchers at OregonStateUniversity have developed a diagnostic test that may soon help producers test for hemorrhagic bowel syndrome.

The polymerase chain reaction test is used to test blood and tissue samples for the mold Aspergillus fumigatus – one of the two main suspected causes of HBS. The other leading theory on the cause of HBS is the organism Clostridium perfringens type A.  

The test was developed by OregonStateUniversity researcher Neil Forsberg and graduate student Steve Puntenney. The test was developed during feeding trials of a feed additive designed by Puntenney to eliminate or neutralize the mold. Initial results on the additive look promising, too.

HBS, also known as jejunal hemorrhage syndrome or bloody gut, is a disease that affects the small intestine in cattle causing large blood clots to form. In most cases the result is death

You can learn more about HBS, including what the research tells us so far, and how to prevent it in the January issue of Dairy Herd Management. It will be available online January 3.
