Abstract
The purpose. To evaluate the contamination of poultry feeds in Ukraine with mycotoxins and other toxic substances. Methods. ELISA, TLC-bioautography, Lebistis reticulatus bioassay. Results. A quarter of the tested feed samples were shown to be contaminated with at least one mycotoxin, and a third — by substances toxic for fish. Only few samples contained mycotoxins in concentrations, which either exceeded or were similar to the permissible levels in poultry feeds. The contamination was least frequent during 2016, and the most — during 2015. The frequency of wheat and maize contamination was lower than that of compound feeds. Conclusions. Generally, the tested feed samples met existing sanitary requirements. However, prevalence and variability of mycotoxin contamination create a necessity for systematic monitoring of feeds quality and corresponding application of prophylactic measures.
