Mycotoxins and the 2009 US harvest

As many of you may know, the delay in this year's harvest due to wet weather conditions in the US has caused some serious concerns regarding the quality of grains, as well as possible consequences that this may have for both grain and animal industries.

It seems that this weather has provided some favorable conditions (e.g. high moisture) for mold growth and potential subsequent mycotoxin production. Producers are recommended to take precautionary steps before incorporating this year corn into their animals’ rations.

This is a clear indication that mycotoxins are and will continue to cause considerable economic losses in the agriculture sector including animal production industries. This, in turn, has a massive impact on the global feed market because the US is a major producer of corn for the animal industry.

Additionally, this situation has a huge effect on production costs at poultry farms around the world, and subsequent increases in the cost of their products for human consumption. 

- This has an effect on the biofuel industry. How will this industry react?

- How much help can commercially available mycotoxin adsorbents provide?

I hope that colleagues from the industry and academia will share their opinions here.

    It would be so easy if all the "wet suspected mycotoxin laden" corn could go towards ethanol production

    Mojtaba, thanks for bringing up an important issue for discussion. Yes, molds and mycotoxins will be a bigger issue in rest of 2009 and 2010, where most of the current crops will be used for poultry production. The major challenge currently faced is from Fusarium mycotoxins, especially DON. Though poultry can tolerate higher levels of DON as compared to pigs, the research has shown that reproduction and immunity are the major aspects affected. Feed refusal can be seen only at very high levels which may be seen when DON occurs along with T-2 toxin. T-2 toxin is also being reported this year in US grains which is much more toxic than DON to poultry. There are certain nutritional interventions that can be used to protect birds from such toxicities. Thanks (shaladi@alltech.com)

    Thank you Dr. Yegani,
    If we use this crops in the poultry feed the essential problem would be seen the immuniosupression it is meaning the less in the vaccine response and the less antibodies production especially in my region we suffered from the IB and IBD and in fact the commercial mycotoxin bender will not enough to adsorbent the high concentration of the mycotoxin all we know the first step in treatment the stock from mycotoxin is excluded the contaminated feed.
