Wet weather brings out the mycotoxins

[Guest guest]

There talking about health affects in animals, they get better health care than

we do

Since there are many kinds of mycotoxins, which differ from each

other, they produce many different kinds of diseases, called

mycotoxicoses. They may cause diseases of the liver, alimentary canal,

smooth muscles, or kidneys. Mycotoxicoses are not contagious.

Wet weather brings out the mycotoxins

This year's relatively cool, wet growing season and rainy fall have delayed

grain harvesting and has increased the risk for mold development on grain. When

mold develops it can increase the formation of mycotoxins which can be toxic to

humans and animals.

 

The Veterinary Diagnostic Laboratory at the Iowa State University College of

Veterinary Medicine reports a higher than normal incidence of affected corn

across Iowa and in samples submitted from six states, Illinois, Kentucky,

Michigan, Oklahoma, Texas and Wisconsin. Samples received from most regions of

Iowa have tested positive for mycotoxins.

 

According to Dr. Steve Ensley, toxicologist with the VDL, " The wet summer and

harvest season have caused a greater incidence of fungi in grains typically used

in livestock feeding. We are receiving samples from throughout the region with

elevated mycotoxin levels, particularly vomitoxin, zearalenone and some

fumonisin. These levels can be tripled if grain is fermented at an ethanol

processing plant, so it pays grain or feed producers to know what may be in the

feed they are producing and feeders to know what they are getting so they can

adjust rations appropriately. "

 

Clinical signs of Mycotoxin-caused problems vary widely by species.

Species-specific effects are included on the VDL website: http://www.vetmed.

iastate.edu/ diagnostic- lab/diagnostic- services/ diagnostic- sections/

chemistry- /-toxicology/ mycotoxins. If you suspect mycotoxicoses is affecting

your animals, contact your veterinarian.

 

Using a new rapid screening test, the Iowa State VDL can analyze feed or grains

for mycotoxins and inform the producer as to the content of the feed made from

the crop. Four mycotoxins typically can be present in the grain and detected in

standard test panels: aflatoxin (more common with hot weather and dry

conditions), fumonisins, deoxynivalenol (DON or vomitoxin) and zearalenone.
