Kanola Yağı İçeren Yemlerle Beslenen Avrupa Deniz Levreği (Dicentrarchus labrax L.)’nin Sindirim Kanalı Boşaltım Süresinin Belirlenmesi

Öz

Bu çalışmada Avrupa deniz levreği (Dicentrarchus labrax) yemlerinde kullanılan, balık yağına ikame olarak, üç farklı oranda (0, 50 ve 100) kanola yağı (Kanola, K) içeren yemlerle (20.4 g) 10 hafta boyunca vücut ağırlıklarının %2’si olacak şekilde beslenmiştir. Besleme denemesinden sonra, her tanka (500 L) 20 adet levrek (78.6 ± 3.58 gram) üç tekerrürlü olarak stoklanmıştır. Sindirim kanalının boşaltım süresinin belirlenmesi için, örneklemeden önce bireyler 72 saat aç bırakılarak sindirim sisteminin tamamen boşaltılması sağlanmıştır. Örnekleme başlamadan önce tüm balıklar tek öğün “ad libitum” olarak beslenmiştir. Her deneme grubundan 0., 8., 16., 24., 32. ve 48. saatlerde tesadüfi olarak 9 adet balık örneklenmiş ve sindirim kanalında mide, ön bağırsak ve son bağırsak olmak üzere üç farklı bölgede kalan yemler tespit edilmiştir. Mide, ön bağırsak ve bağırsaklardaki en kısa boşaltım sürelerinin sırasıyla 32.2; 60.9 ve 50.4 saat ile K0 grubunda (%0 kanola yağı) olduğu bulunmuştur, en uzun sürenin ise sırasıyla 41.9; 101.3 ve 70.2 saat ile K100 (%100 kanola yağı) grubunda olduğu belirlenmiştir (P<0.05). Deneme sonunda ulaşılan veriler, yem içerisinde balık yağına ikame olarak kullanılan kanola yağı oranın artması ile boşaltım sürelerinin doğrusal olarak tüm sindirim sisteminde uzadığını ve levrek yemlerinde bu yağın yem formülasyonlarında yüksek oranlarda kullanımını sınırlandıracağını göstermiştir.
