Sarı prenses (Labidochromis caeruleus) yavrularında kanola küspesi içeren yemlere selülaz ve fitaz enzimi ilavesinin yem dönüşüm oranı ve büyüme performansı üzerine etkileri

Öz

    Sarı prenses (Labidochromis caeruleus) yavrularında (başlangıç ağırlığı 0,6±0,02 g) kanola küspesine dayalı yemlerine selülaz ve fitaz enzim ilavesinin büyüme performansı ve yem dönüşüm oranı üzerine etkilerini araştırmak için 8 haftalık bir besleme çalışması yürütülmüştür. Denemede % 32 kanola küspesi içeren kontrol yemine % 0,1 fitaz ve selülaz enzimi ilave edilerek üç deneme yemi hazırlanmıştır. Besleme denemesi 9 akvaryumda 3 tekerrürlü yapılmıştır.  Deneme başında her bir akvaryuma 20 balık stoklanmıştır. Deneme sonunda, % 32 kanola küspesi içeren yemlere fitaz ve selülaz enzimi ilavesinin büyüme parametreleri ve yem dönüşüm oranı üzerine etkisinin önemli olmadığı tespit edilmiştir (P>0.05). Bununla birlikte, deneme sonunda, daha yüksek ortalama ağırlık, ağırlık kazancı, spesifik büyüme oranı kontrol ile beslenen deneme grubundan elde edilirken, daha düşük değerler yeme selülaz ilavesi ile beslenen deneme grubundan elde edilmiştir.

Effect on growth performance and feed conversation ratio of addition phytase and cellulase enzyme to diets containing canola meal in yellow cichlid (Labidochromis caeruleus) fry

Abstract

A 8-week feeding trial was conducted to evaluate the effects of addition of cellulase and phytase to diet containing canola meal on growth performance and feed conversion ratio of 0.56±0.02g yellow cichlid fry (Labidochromis caeruleus). Three diets were prepared by adding 0.1 % cellulase and phytase to the control diet including 32 % canola meal. The feeding trial was conducted in triplicate in 9 aquariums. At the beginning of the experiment, 20 yellow cichlid fry were stocked into each aquarium. At the end of the experiment, the addition of cellulase and phytase to diet containing 32% canola meal did not have effect on the growth parameters and food conversion ratio (FCR) (P > 0.05). However, higher mean weight, weight gain, specific growth rate were obtained from the experimental group fed with the control diet, while lower values were obtained from the experimental group fed with cellulase supplement at the end of the experiment.
