Abstract

Zeranol is a synthetic derivative of Zearalenone which has been used as an anabolic substance in sheep and cattle to increase growth of zeranol in food producing animals. The usage of zeranol is prohibited in most countries of the European Union and in Turkey. In the illegal use of zeranol it is difficult to determine its presence because the amount of zeranol given and period is not known. As well as this, the age and breed of the animal plus individual variations affect the period of removal of zeranol from the body. Because of this rapid, sensitive and accurate techniques are needed and Radioimmunoassay (RIA) has been proposed as an reference method for anabolic agent residues.Faeces, serum and tissue samples of lambs from Ankara and the surrounding countryside were collected and the analyses of zeranol, oestrogen, progesteron and testosteron were carried out using Radioimmunoassay. A total of 153 faeces samples of lambs collected from Ankara and the surrounding countryside were analysed for the presence of zeranol positive samples for lamb faeces were 22%.

Özet

Zearalenone'un sentetik bir derivesi olan Zeranol, koyun ve sığırlarda besi performansını artırmak amacıyla anabolik madde olarak kullanılmıştır. Avrupa Birliği ülkelerinde ve Türkiye'de tüketiciye ulaşabilecek kalıntıları nedeniyle hayvanlarda kullanımı yasaklanmıştır. Yasal olmayan kullanımlarında, verilen miktar ve süre bilinmediğinden tesbiti güçtür. Bunun yanında hayvanın yası, cinsi ve bireysel farklılıklar da zeranol'ün vücuttan uzaklaşmasında etkilidir. Bu nedenle hızlı, duyarlı teknikler kullanılmalıdır ve Radioimmunoassay, referans metot olarak önerilmektedir. Ankara çevresinde çiftlik ve mezbahalardan toplanan dışkı ve doku örnelerinde zeranol analizleri ile serum örneklerinde testosteron, progesteron ve östrojen hormon analizleri Radioimmunoassay ile yapılmıştır. Toplam 153 kuzu dışkı örneği zeranol yönünden analiz edildi. Kuzularda % 22 zeranol pozitif bulundu.
