Tricotecenes are mycotoxins with a common chemical structure that holds the sesquiterpene ring and 4 radicals that change depending on each mycotoxin.

The sesquiterpene ring gives the capability to produce chemical burning by contact in digestive tract epithelia.

Photos may show injuries in the glandular zone of gizzard.

This injury reduces the capability of secreting acis and thus, reduces also digestibility of feed, in consequence an important part of protein remains with no digestion, and an increase of Clostridium growth is produced in duodenum. Economical loss up to a 20 and 30% of feed value may be concerned to sesquiterpenes.
