Guarding against deoxynivalenol in swine feeds

Even at low concentrations, this mycotoxin can lead to reduced weight gain, vomiting, feed refusal, impaired immune function and poor gut health in pigs.
Deoxynivalenol (DON) is a major mycotoxin commonly found in mild climatic regions of North America, Europe and North Asia. In swine feed commodities worldwide, DON occurred in 79 percent of finished feed samples, 77 percent of corn samples and 92 percent of dried distillers grains with solubles (DDGS) samples analyzed.

It should be noted that the common active group of all trichothecenes is the epoxide, which are responsible for the binding of DON to ribosomes inhibit protein synthesis.
