		Understanding My Results What is mold? Mold is a term used to describe various fungi that grow in animal feed and degrade the quality of that feed. Mold growth is estimated to reduce feed value by at least 10%. Mold germinates at temperatures as low as 45 degrees F, with most rapid growth at 75 to 90 degrees F. They require humidity for germination, therefore, an upper limit of 14.5% moisture is recommended for stored corn or milo. Other grains should maintain moisture levels less than 13%.
