The Effects of The Carvacrol and Thymol Addition to Pangasius Hypophthalmus Feeds in Different Amount on the Growth Performance

Öz

In the present study we investigated the effects of phytoadditive carvacrol and thymol on growth performance and feed utilization of Pangasius hypophthalmus. In trial, 840 Pangasius hypophthalmus which had average weight of 1.33 ± 0.05 gram was used. Fish were divided into seven groups before being fed for 90 days with 0, 1 (C1), 3 (C3), 5 (C5), 1(T1), 3(T3), 5(T5) g/kg of carvacrol and tymol. All treatment groups were planned three replicate and randomly plots method and fish were distributed to groups. It was determined that 3 g/kg timol addition to feed provided the best result in terms of growth performance.

Karvakrol ve Timolün Pangasius hpophthalmus Balıklarının Büyüme Performansı ve Yem Dönüşüm Oranı Üzerine Etkisi

Öz

Bu çalışmada, bitkisel kaynaklı karvakrol ve timol ektraktlarının Pangasius hypophthalmus balığında büyüme performansı ve yem tüketim üzerine etkileri araştırılmıştır. Çalışmada ortalama ağırlık 1.33 ± 0.05 g olan 840 adet Pangasius hpophthalmus balığı kullanılmıştır. Çalışmada 0, 1 (C1), 3 (C3), 5 (C5), 1 (T1), 3 (T3), 5 (T5)  g / kg yem oranında  karvakrol ve timol  ile 90 gün balıklar beslenmiştir. Tüm deneme grupları 3 tekerrürlü olarak planlanmış ve tesadüfi parselleme metoduna göre balıklar gruplara dağıtılmıştır. Büyüme performansı bakımından en iyi sonucu yeme 3 g/kg timol ilavesinin sağladığı belirlenmiştir.
