Abstract
The article presents the results of veterinary and sanitary examination of meat of
broiler chickens 42 days old when using a four-component sorbent (shungite, zeolite, lignin and
glucan) in feed with experimental mixed mycotoxicosis (T-2 toxin, aflatoxin B1, DON, zearalenone,
fumonisin B1).
It was found that in the study of chicken carcasses of group 4 (daily intake of mycotoxins without
the use of sorbent), there were small deviations from the norm, leading to a reduction in shelf life,
in the form of a decrease in muscle consistency, an increase in meat moisture and the appearance of
a slightly sour smell. Microscopy of smear prints taken from different muscle layers of broilers of
this group showed the presence of single coccoid and rod-shaped microorganisms in the deep and
surface layers of muscle tissue. At the same time, the pH of meat in the group of chickens treated with
mycotoxins was 6,5, while in the other groups it ranged from 6,0 to 6,1. The reaction to peroxidase
of poultry meat samples of chickens treated with mycotoxins was negative, the reaction with copper
sulfate was positive; when setting the formative reaction, the extract was cloudy and contained fine
flakes. The introduction of the sorbent into the mycotoxin-contaminated diet helped to improve the
indicators of veterinary and sanitary analysis of chicken meat to the level of control.
