The present study investigated the effects of the prebiotic inulin on the growth parameters, digestive enzyme activities and antioxidant status of rainbow trout (Oncorhynchus mykiss). After acclimation, fish (34±0.22 g; n = 135) were assigned into 9 tanks (15 fish per tank) and triplicate groups were fed a control diet (G-0) or diets containing 1% (G-1) or 2% (G-2) inulin. At the end of the trial (8 weeks), growth factors (final weight, weight gain, specific growth rate (SGR), food conversion ratio (FCR), protein efficiency ratio (PER), Economic conversion ratio (ECR), digestive enzyme activities (pepsin, trypsin, amylase and lipase) and antioxidant status superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) level of liver tissue were assessed. At the end of the study highe...

YILMAZ, FERBAL ÖZKAN | HUNT, ARZU ÖZLÜER
In this study, it was evaluated Glutathione S transferase (GST), Adenosine deaminase (ADA), and paraoxonase (PON) activities in liver tissue of Oncorhynchus mykiss fed with nucleotide yeast base protein supplemented diet. Throughout the 60-day period the control group was fed a fish meal based basal diet, and three other groups were fed diets in which 20% (NP 20), 40% (NP 40) and 60% (NP 60) fish meal was substituted with nucleotide (Nu-Pro® (NP) yeast). At the end of experiment, liver tissue GST, PON and ADA activity was increased significantly (P
Effects of Organic Selenium on Growth, Muscle Composition, and Antioxidant System in Rainbow Trout
HUNT, ARZU ÖZLÜER | YILMAZ, FERBAL ÖZKAN | YALIN, SERAP
This experiment was conducted to understand the effects of organic selenium on rainbow trout, Oncorhynchus mykiss. Fish (33.47±0.15 g; n = 216) were randomly assigned to four treatment groups consisting of three replicates of 18 fish each in 100 x 100 x 125 cm cages. The fish were fed a basal diet supplemented with 2, 3, or 4 mg/kg organic Se (Sel-Plex®) supplementation for 8 weeks. Muscle of fish fed the unsupplemented control diet had a lower (p
