Sažetak
Coccidiostats are often used as additives in poultry breeding due to their prophylactic and therapeutic effects. According to Commission Regulation (EC) No 109/2007, monensin is authorised in feedstuffs at maximum doses of 125 mg/kg, and maduramicin at a maximum content of 5–6 mg/kg ((EU) No 388/2011). In the present study, laying hens, as the non-target species, were treated with maduramicin and monensin added to feedstuffs below and at the concentration authorised for target species. Hens were divided into groups and fed for 14 days with medicated feed. Two groups were treated with feed containing maduramicin at 1 and 5 mg/kg, while two groups were treated with feed containing monensin at 62.5 and 125 mg/kg. The control group received feed free of coccidiostats. Eggs were collected during the treatment period and 26 days after withdrawal of the medicated feed. Maduramicin residues were determined solely in egg yolk, while residues of monensin were determined in both egg white and yolk. The transfer factor was significantly higher for maduramicin than for monensin. Residue levels of maduramicin and monensin in eggs, after administration at the maximum concentration in feed, were below the maximum residue limits for eggs after 16.6 days and 6.0 days, respectively.
