Table 14.

Concentration of furocoumarins and methoxycoumarins in feed for chickens for fattening (as μg/kg complete feed) and intake of chickens for fattening (as μg/kg bw per day) calculated at the maximum proposed use level of the additive in feed (12 mg/kg) and considering the average and the maximum analysed value for each congener in the additive
