Kesim Öncesi Bilinçsizleştirme Akım Seviyesinin Etlik Piliçlerin Karkas ve Göğüs Eti Kalitesi Üzerine Etkisi

Bu çalışma, elektrik akımıyla bilinçsizleştirmenin etlik piliçlerin karkas ve göğüs eti kalite özellikleri üzerine etkisini belirlenmek amacı ile yürütülmüştür. Piliçleri bilinçsiz hale getirmek için 90, 120 ve 150 mA, 400 Hz pulslanmış doğru akım (pDC) uygulamıştır. Her bir uygulama için 20 (10♀:10♂), toplamda 60 piliç kullanılmıştır. Piliçlere 4 sn süre ile su banyosunda elektrik akımı uygulanmıştır. Bilinçsizleştirme sırasında her bir piliç için üzerinden geçen gerilim ve vücut direnç değerleri belirlenmiştir. Bilinç kaybından sonra, piliçlerin canlı olup olmadıkları kontrol edilmiş ve kesilmiştir. Kesilen piliçlerde kan kayıpları, karkasta oluşan damar kanamaları, spot lekeler ve kanat kısmına ait kemik kırıkları tespit edilmiştir. Göğüs etinin kalitesi, etin pH’sı (kesildikten 15 d ve 24 saat sonra), su kaybı, pişirme kaybı ve sertliği belirlenerek değerlendirilmiştir. Elektrik akımı değerleri piliçlerin göğüs etinde sadece su kaybı üzerinde etkili olmuştur (P<0.05). Uygulanan 120 mA’lik akım düzeyi piliçlerin göğüs etinde daha düşük su kaybına yol açmıştır. Elektrik akımının incelenen diğer özellikler üzerindeki etkisi önemli bulunmamıştır (P>0.05). Sonuç olarak, bu çalışmada incelenen tüm özellikler dikkate alındığında, etlik piliçlerin kesim öncesi bilinçsizleştirilmesinde pDC 120 mA (400 Hz) akım uygulamasının daha etkili olduğu sonucuna varılmıştır.
