Abstract

One of the pressing issues frequently encountered in modern poultry farming is the emergence and spread of mycotoxicoses, which can negatively affect the health of farm birds and cause significant economic losses for poultry producers. One of the most dangerous mycotoxicoses in industrial poultry farming is T-2  mycotoxicosis, caused by the trichothecene mycotoxin produced by fungi of the Fusarium genus. It is known that T-2 toxin has pronounced cytotoxic, immunosuppressive, and hematotoxic effects, leading to reduced productivity indicators in poultry, a weakened immune status, and increased susceptibility to infections, which often develop as a result of the negative impact of mycotoxins on the bird's body. The aim of our study was to investigate the effect of T-2 toxin on the morphological parameters of blood and the productivity of broiler chickens, as well as to assess the effectiveness of the feed bioadsorbent “BioBon” in preventing T-2 toxicosis. The experiment included three groups of broiler chickens, each consisting of 30 birds: a control group, an experimental group 1 (with the addition of 0.2 mg/kg of T-2 toxin to the feed), and an experimental group 2 (with the addition of T-2 toxin and the bioadsorbent "BioBon"). From days 15 to 28 and then to 35, the hemoglobin content in the blood of all groups increased, followed by a decrease on day 42. However, we observed a tendency for an increase in hemoglobin levels in the blood of the birds in the second experimental group by 2.40% compared to the control group. On day 28, the broiler chickens in the first experimental group showed a marked decrease in leukocyte count by 22.88% and lymphocyte count by 18.04%, indicating a pronounced immunosuppressive effect of the T-2 toxin when added to the diet of broiler chickens in this group. The bioadsorbent “BioBon”, when added to the compound feed at a dose of 2 kg/ton, neutralized the negative effects of the T-2 toxin on the experimental broiler chickens, resulting in an increase in slaughter weight up to 2917 g, and also contributed to a reduction in the feed conversion ratio to 1.690 kg/kg.
