Spray-Dried Plasma Can Mitigate Negative Mycotoxin Impact12 August 2013
CANADA - The presence of DON contamination in grain is directly related to the presence of head or ear blight produced by Fusarium fungi, which in turn is directly related to the moisture content at flowering.
Possibly due to recent high stress growing seasons, we have seen an increase in the presence of DON contaminated grains in the Prairie Provinces, and it is expected that DON contamination will continue to spread.
With the cool summer and high rainfall in parts of the Prairies throughout 2013 there is a high probability that livestock producers will see DON in feed grains come this fall.
The best strategy for dealing with contaminated grains is to reduce the final concentration of the mycotoxin by dilution; however, this may not be possible if large quantities of contaminated grain are available.
Feeding DON contaminated diets to pigs has negative effects on performance, and can also affect intestinal integrity. Contrary to this, including SDAP into swine rations leads to improved performance and has positive benefits on gut health and integrity.
This led to the hypothesis that feeding SDAP to pigs consuming DON contaminated diets would mitigate the negative effects on performance.
The use of activated clay binders is another strategy designed to help reduce the negative effects of certain mycotoxins in livestock, and thus it was also hypothesized that adding an activated clay to the diet would improve animal performance in DON fed pigs.
