I did a lot of research with Wet Distillers Grains several years ago. I was trying to find a combination of Organic Acids and an application rate that would preserve the WDG to extend shelf life for livestock producers.
I found that if the WDG was not treated with a preservative it would mold within 3 days during the heat of summer and 5 to 7 days in the spring and fall. Since the moisture acts like a sealant, the WDG underneath the mold layer is fine, but molds very quickly once exposed to air.
In addition to molds, we found that Yeasts loved to grow on the WDG and you would not see a growth as a result like you would with a mold.
If you can get it fed quickly it is a good supplement, but be very careful of any mold growth as you can decrease growth rate, compromise the immune system, induce abortions, and severly inhibit the reproduction if the pigs consume high levels of mycotoxins which are released by molds.
