The present paper describe the pertaining clinical symptomatology as well us histopatology, microbiological data and mycotoxin analysis.

When these feed samples wre analysed for aflatoxins fB), B2. and Gj pins stcrigmatocystin, ochratoxin A and zearalenonej, zearalcnonc was detected in two samples at the level of 19.
