Determination of natural adverse factors (aflatoxins, nitrate, nitrite, tannin and sodium chloride) in some cage bird feeds

Öz

This study was carried out to determine the levels of aflatoxins, nitrate, nitrite, tannin and sodium chloride in some cage bird feeds sold in Ankara, Turkey. A total of 60 feed samples (20 each of budgerigar, canary and parrot feed) were analysed. Aflatoxin analyses by HPLC, nitrate, nitrite and tannin analyses spectrophotometrically and sodium chloride analyses by a method based on colour reaction were performed. Total aflatoxin was found to be 2.44-34.30 ppb in 11 budgerigar feeds, 0.91-16.75 ppb in 8 canary feeds and 1.43-19.29 ppb in 10 parrot feeds. Nitrite (0.00-6.19 ppm), nitrate (1.31-25.55 ppm), tannin (0.04-0.74%), and sodium chloride (0.05-0.44%) were found in all feeds. As a result, it was concluded that the amount of AFB1 in only 1 budgerigar feed might pose a risk to the health of cage birds, while the amounts of nitrate, nitrite, tannin and sodium chloride might not cause any health problems.

Bazı kafes kuşu yemlerinde doğal olumsuzluk faktörlerinin (aflatoksin, nitrat, nitrit, tanen ve sodyum klorür) belirlenmesi

Öz

Bu çalışma, Ankara'da satılan bazı kafes kuşu yemlerinde aflatoksin, nitrat, nitrit, tanen ve sodyum klorür düzeylerini belirlemek amacıyla gerçekleştirildi. Toplam 60 yem örneği (muhabbet kuşu, kanarya ve papağan yeminin her birinden 20 adet) analiz edildi. HPLC ile aflatoksin analizleri, spektrofotometrik olarak nitrat, nitrit ve tanen analizleri ve renk reaksiyonuna dayalı bir yöntemle sodyum klorür analizleri yapıldı. Toplam aflatoksin 11 muhabbet kuşu yeminde 2.44-34.30 ppb, 8 kanarya yeminde 0.91-16.75 ppb ve 10 papağan yeminde 1.43-19.29 ppb olarak bulundu. Tüm yemlerde nitrit (0.00-6.19 ppm), nitrat (1.31-25.55 ppm), tanen (%0.04-0.74) ve sodyum klorür (%0.05-0.44) bulundu. Sonuç olarak, sadece 1 muhabbet kuşu yemindeki AFB1 miktarının kafes kuşlarının sağlığı için risk oluşturabileceği, nitrat, nitrit, tanen ve sodyum klorür miktarlarının ise herhangi bir sağlık sorununa neden olmayabileceği sonucuna varıldı.

Anahtar Kelimeler
