![]() The Food and Drug Administration guidelines allow no more than 20 parts per billion of aflatoxin in animal feeds.Īflatoxin contamination of grains is not a common problem in the North Central U.S. Aflatoxin is a carcinogenic compound that causes anemia and stunted growth in pigs when present at 200 parts per billion. Aflatoxin contaminationĪspergillus flavus produces the toxin aflatoxin. The following molds are known to harm pig performance. There are some mold toxin tests available for on-farm testing. Commercial laboratories can test your grain for mold toxins. A presence of mold doesn’t mean toxins are present. Molds produce toxins that depress pig performance. High moisture in stored grain enhances mold growth. Rodents will eat the grain and contaminate it with droppings leading to reduced grain palatability by pigs.Protect the grain from rodent damage and mold contamination while in storage.Avoid temperatures over 300 degrees F when artificially drying grains.Make sure the grain is about 12 to 15 percent moisture for safe storage.Broken kernels more likely support mold growth than intact kernels.Avoid using a high proportion of broken kernels.Make sure all grains are free of molds, insects, dirt, stones and other debris.The following tips can help you achieve quality control. These results show the importance of quality control when mixing your own feed. ![]() Low-protein diets resulted in depressed average daily gain, poor feed efficiency and high production costs. Workers at Purdue University found when protein rises above 15 percent, feed costs increase but performance doesn’t improve in market hogs. Such errors in feed can have an economic impact on swine producers.
