THE DETERMINATION OF DIETHYLSTILIJESTROL (DES) IN THE FAECES AND TlSSUES OF CHICKENS TREATED WİTH DES AND IN THE FAECESAND TISSUE SAMPLES OF CALVES, LAMBS AND CHICKENS COLLECTED FROM VARIOUS AREAS OF TURKEY

Abstract

DietllJ-lstiibestrol (DES) arw[vses wae earried out on muscle, lher, kidne;' and faeees samples ~L20 control and 20 experimentai broi!ers to whieh 5 mg DES jday had been given oraily for a period of 7 days. The treated samples were ana!)'Sed ıısing the Radioimmu1iOassa..J'metlzod. The removal time ~f DES from the tiSSl/es was determined. Five da)'s following the jinaladmi,!istration of DES, İtç faceJ,! ceneentration was ]51 ppb. However 7 doys after the fina i administratioıı laeeal DES eoneentrations inereased again. On the first day ajter the finel DES administration, DES eoneentrations in the lfvcr, musr:leand kidll~v werc 0.78, O.H and 1.3') ppb mpeetiuely. ırhile these ı'aiuer measured on thefinal da,)'were ,dthin the ralZge~f tlze (ontrol values. There mas an inerease ofDFS in plasnıa at the end of the fixperimental peri'Jd. A total of 1811 musele, liver, kidn~y and/aeees samples oj ealves, lambs and r:hickenr and feed samples eolleeted from ut!.rious areas in Turkey were ana!)'sed for the presence of DES positive samples for ehieken feed was 36.9 %. Alsa 1.9 % ol the ehieken .laeees sanıples ,I'ere DES positive. All other samjJleı u;ere Jlr,2,atiu~for DES.
