Manifestations of disease caused by T-2 toxin and its metabolites (necrosis in the oesophagus, decreased appetite, liver damage, diarrhoea, reduce livestock performance,decrease in body weight) is often observed in the poultry industry that employs the largest share of grain and grain products. Therefore, the aim of our work was to find optimal ways to prevent mycotoxicoses, mainly the study of the influence of some individual sorbents on trichothecenes content.
In the article there are results of content of T-2 and HT-2 toxins in various components of poultry’s food (wheat, triticale, peas, barley, corn) performed by ELISA. Established natural contamination studied samples of corn and barley at concentrations of 0.15 and 1.8 ng/g grain, respectively. Four groups of samples were formed to study the effectiveness of certain drugs (aerosil, «Kormosan» ceolite, «Mykotox») that neutralize trichothecenes toxins. Samples were incubated at the temperature of 38˚C. Gastric juice and bile was added accordingly to physiological norms of individual sections of chicken’s digestive system. Analyzed the ability of these drugs to neutralize toxins studied in vitro within the crop, stomach and intestines. Found high rates of sorption by aerosil and «Kormosan» of researched mycotoxins in feeds. However, comparing the obtained experimental data in different parts of the digestive tract of chickens aerosil was the most effective sorbent.
