title: [The transition of morantel in cow's milk following administration in the retard form, "Paratect Bolus" (Pfizer)].
abstract: The transition of Morantel into bovine milk was studied with three lactating cows. The active compound was administered as Paratect Bolus which continuously releases the anthelmintic agent. No residues of Morantel could be detected throughout the 92-day experiment (limit of detection: 0.5 micrograms Morantel tartrate/kg milk), nor could the compound be found in the blood serum at day 35 of the experiment. The same day an amount of 825 micrograms/kg was observed in faeces.
