Enzyme supplementation to soybean based diet in gilthead sea bream (Sparus Aurata): effects on growth parameters and nitrogen and phosphorus excretion

Öz:
Bu çalışmada, soya küspesi (%40) kullanılarak yetiştiriciliği yapılan çipura (Sparus auratus) balık yemlerine bazı ticari enzimlerin ilave edilmesinin büyüme performansı, yemden yararlanma, sindirilebilirlik ve azot-fosfor atılımının etkilerini araştırma amaçlanmıştır. Denemede %40 balık unu + %25 soya küspesi ticari çipura yemi (CF) ve %25 balık unu + %40 soya küspesi (enzim ilavesiz) kontrol grubu (CO) ile enzim 1 ilaveli (PRT: Proteaz; 2 g/kg -1), enzim 2 (MIX; cellulose, xylanase, endo-β-1,3:1,4-glucanase; 2 g/kg -1), enzim 3 (PHY: Fitaz; 2 g/kg -1) içeren toplam 5 grup yem kullanılmıştır. Denemede 2 x 0.5 x 0.23 m. ebadında, tanklar kullanılmış ve her tanka 55 adet (başlangıç ağırlığı ort. 89.50±1.5 g) çipura balıkları 5 grup halinde üç tekerrürlü rastgele olarak yerleştirilmiş ve deneme 12 hafta sürmüştür. Deneme sonunda gruplar arasında ağırlık artışı (125.00–133.50 g) ve spesifik büyüme oranı (0.42–0.50) istatistiki olarak farklılık göstermezken (p>0.05), özellikle proteaz (PRT) ve fitaz grubu (PHY) kontrol grubuna (CO) göre yem değerlendirme (2.52–2.90) ve kondüsyon faktörü (1.85–2.08) açısından farklılık elde edilmiştir (P<0.05). Bu çalışmada en yüksek azot sindirilebilirliği proteaz (PRT) grubunda (83.20±1.98), en düşük kontrol (CO) grubunda (69.72±0.01) elde edilmiştir. Fosfor sindirilebilirliği ise en iyi fitaz (PHY) grubunda (58.57±0.49), en düşük ise kontrol (CO) grubunda (42.85±1.98) gözlenmiştir (P<0.05). Sonuç olarak bu çalışmada farklı enzim uygulamalarının büyüme, yemden yararlanma ve sindirilebilirlik üzerine pozitif etkisi gözlenmiştir. Bu pozitif etki sadece balık unu yerine soya küspesi kullanımı açısından değil, aynı zamanda performans bakımından da olumlu sonuçlar ortaya çıkarmıştır.

The aim of the present study was to examine the effects of the diets based on soybean meal supplemented with exogenous enzymes on growth performance, feed utilization, apparent digestibility and waste output of nitrogen and phosphorus in gilthead sea bream (Sparus aurata) culture. Diets consisted of 40% fish meal (FM) and 25% dehulled hexane extracted soybean meal (SBM) in commercial feed (TM) and 25% fish meal (FM) and 40% dehulled hexane extracted soybean meal (SBM) in control group (CO), and diet supplemented with enzyme 1 (PRT= Protease; 2 g/kg -1), diet supplemented with enzyme 2 (MIX; cellulose, xylanase, endo-&#946;-1,3:1,4-glucanase; 2 g/kg -1) and diet supplemented with enzyme 3 (PHY: Pyhtase; 2 g/kg -1). A stocking design at 55 fish each tank, gilthead sea bream (initial weights 89.50±1.5 were randomly total of 825 fish allocated into 15 tanks and fed five experimental diets. While weight gain (125.00&#8211;133.50) and specific growth rate (0.42&#8211;0.50) were statistically similar (P>0.05), feed efficiency ratio (2.52-2.90) and condition factor (1.85-2.08) significantly different among groups (P<0.05) at the end of the experiment. Addition of PRT and PHY into control significantly improved specific growth rate, feed efficiency ratio and condition factor. In this study, showed the highest nitrogen apparent digestibility coefficient (83.20±1.98) in group of PRT whilst the poorest value obtained (69.72±0.01) group of CO. The best (58.57±0.49) and the lowest (42.85±1.98) ADC for phosphorus were obtained from PHT and CO, respectively (p<0.05). In conclusion, this study has shown that dietary different enzyme supplementation can have a positive effect on growth, feed utilization and digestibility in gilthead sea bream. This positive effect has been not only alleviate the negative effect of replacing dietary FM with SBM but also provide about better performance compared to fish fed a higher FM containing diet.
