Influence of fungi and their metabolites on the health status of wildgame.
BOHÁČKOVÁ, Lenka
The aim of this thesis was to evaluate the examined samples of liver tissue to find out the amount of aflatoxin in deer game. A total of 221 samples were examined for analysis purposes using the RIA method. Samples were obtained from dead and captured heads of deer game coming from private game reserves and game reserves belonging to the Forests of the Czech Republic. Samples of deer game were divided into groups according to their types, sex, and age. Sex was determined visually, and age via the development and grinding of the teeth. The highest concentration of B1 aflatoxin in liver was measured in a 6 year-old dead female (7,39 g.kg-1). According to the statistical evaluation (P <0,05), a significant difference was proven between dead and captured heads, between males and females, and even between age groups. There is a higher aflatoxin B1 concentration in dead heads´ liver, approximately in 2,12 g.kg-1 higher than in captured heads. Females´ liver proved to contain a higher concentration of B1 aflatoxin, approximately in 0,63 g.kg-1 higher than in males. Age groups have proven that the older the animals, the higher the B1 aflatoxin concentration in their liver.
