A mycotoxin, classified as a type A trichothecence, produced by various Fusarium moulds. Causes feed refusal and gastrointestinal lesions in cattle and gizzard erosions and lesions of the upper digestive tract in poultry, causing reduced productivity in many species.
A complete ration, fed to livestock, containing different feedstuffs used to meet their nutritional requirements. A TMR for cattle may contain a mixture of silage, concentrates and other ingredients depending upon what the farmer and nutritionist decide is most suitable. If collecting samples to analyse for mycotoxin contamination, the TMR should be used to give a representative sample of the entire diet fed to the animal.
Largest family of mycotoxins produced by Fusarium species, divided into 4 subgroups, with 2 major groups being type A and type B trichothecenes. Type A trichothecenes include T-2 toxin, HT-2 toxin and Diacetoxyscirpenol (DAS). Type B trichothecenes include deoxynivalenol (DON) and nivalenol.
