Yavru Nil Tilapyalarında (Orerochromis niloticus L.) Büyüme Performansı ve Vücut Bileşimi Üzerinde Yemleme Sıklığının Etkisi

Bu çalışmada Nil Tilapyalarının büyüme performansı, ortalama yem tüketimi, yemden yararlanma oranı ile toplam vücut ve karkas kompozisyonu üzerinde yemleme sıklılığının (günde 1, 2, 3 ve 6 öğün) etkisi araştırılmıştır. Denemede, ortalama ağırlığı 9.39±0.19 g olan 420 adet Nil Tilapyası kullanılmıştır. Bu amaçla her biri 3 paralelden oluşan 4 grup oluşturulmuş ve çalışma 10 hafta sürmüş olup, her bir tanka 35 adet balık stoklanmıştır. Çalışmada % 35 ham protein (HP) ve 11.7 MJ/kg sindirilebilir enerji (SE) içeren ticari bir yem kullanılmıştır. Deneme sonunda, ortalama canlı ağırlık, canlı ağırlık artışı, yem tüketimi, yemden yararlanma oranı, proteinden yararlanma oranı ve özel büyüme oranı bakımından gruplar arasında önemli fark bulunmuştur (P

The Effects of Feeding Frequency on Growth Performance and Proximate Composition of Young Nile Tilapia (Oreochromis niloticus L.)

In this study, the effects of four different feeding frequency (once (I), twice (II), three (III), or six (VI) meals a day) on the growth performance, feed consumption, feed conversion ratio and proximate composition of Nile Tilapia (Oreochromis niloticus) were investigated. The average live weight of 420 Nile tilapia used in this experiment were 9.39 ± 0.19 g. Four trial groups were tested in triplicate for 10 weeks and 35 fish were stocked in each tank. The fish were fed with the feed (35% CP; 11.7 MJ DE/kg) taken from a commercial feed company. At the end of the study, it was observed that there were important differences among the groups in terms of average live weight, live weight gain, feed consumption, feed conversion ratio (FCR), protein efficiency ratio (PER) and specific growth ratio (SGR) were found statistically significant (P
