RESUMO
When Road-Island breed chickens were given fodder which included toxin in concentration of 16 mg/kg or T-2 toxin in concentration of 10 Mg/kg, that resulted in the decrease of the live weight, increase in the relative weight of the liver, kidneys, pancreas and heart, as well as the decrease of concentration of Bacillus genus bacteria in the caecum and rectum content compared with the control group chickens. No distinctions were observed in activity of alanine aminotransferase and concentration of total protein in the blood plasm. The drinking of probiotic preparation BPS-44 when feeding with forage contaminated by HT-2 or T-2 toxin resulted in the increase of the live weight, normalization of relative weights of viscera, increase in concentration of Bacillus genus bacteria in the intestine compared with chickens which received only mycotoxins.
