The Effects of Balanced Diets with Soy Bean Extract or Meat and Bone meal on Muscle and Liver Tissue Protein and Glycogen Levels of the Nile Tilapia (Oreochromis niloticus L.) Infected with Vibrio anguillarum

FERBAL ÖZKAN YILMAZ | KENAN ENGİN | ARZU ÖZLÜER HUNT

This study investigated the effects of balanced diets with solvent extracted soy bean and meat and bone meal on the levels of protein and glycogen in muscle and liver tissues of the Nile tilapia (Oreochromis niloticus L.) infected with Vibrio anguillarum. Compared to the control diet (fishmeal only), diets with solvent extracted soy bean (SBM) and meat and bone meal (MBM) significantly lowered (P

Effects of Dietary Cottonseed and/or Canola Oil Inclusion on the Growth Performance, FA Composition and Organ Histology of the Juvenile Rainbow Trout, Oncorhynchus mykiss

KENAN ENGİN

This study aimed at demonstrating the effects of total and 50% dietary fish oil replacement by cotton seed and canola oils and a mixture of these vegetable oils (VOs) on growth, tissue fatty acid composition and histology of digestive organs in the juvenile rainbow trout for 84 days. Five iso-nitrogenous and lipidic diets were formulated to replace dietary fish oil (FO) totally by cotton seed oil (CSO), canola oil (CO) and an equal or 50% FO/ 50% VO mixture. Duplicate groups of 50 fish (~15 g) were fed two times daily to apparent satiation. Growth performance, feed efficiency and viscerosomati ...Daha fazlası

Effects of Dietary Nucleotide Yeast on Immune Responses and Antioxidant Enzyme Activities of Rainbow Trout Juveniles (Oncorhynchus mykiss)

ARZU ÖZLÜER HUNT | FERBAL ÖZKAN YILMAZ | KENAN ENGİN | SERAP YALIN

This study aimed at demonstrating the effects of dietary supplementation of nucleotide yeast base protein (Nu-Pro®) (NP) on the antioxidant enzyme activities and immune response in liver and blood tissues of rainbow trout (Oncorhynchus mykiss). Fish with an average initial weight of 27.75±0.26 g were randomly assigned to four groups with three replicates. Throughout the 60 day grow-out 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 ...Daha fazlası

Partial Replacement of Fish Oil with Vegetable Oils in Diets for EuropeanSeabass (Dicentrarchus labrax): Effects On Growth Performance and FattyAcids Profile

KENAN ENGİN

The study was conducted to determine the effects of alternative oil sources on growth, body composition and feed conversion of sea bass individuals. The tested oils used in the study were as follows: sesame oil (SO), canola oil (CO) and soybean oil (SBO). All tested oils were included at a 50% substitution level of fish oil and were compared with a control diet containing 100% fish oil (FO). There was no effect of diet on specific growth rate. The highest final weight was seen in fish fed SO and FO diets compared to that of fish fed CO diet and SBO diets (P0.05). In the n-6 fatty acids, fish f ...Daha fazlası

Fatty acid metabolism in European sea bass Dicentrarchus labrax effects of n 6 PUFA and MUFA in fish oil replaced diets

KENAN ENGİN

Monounsaturated fatty acids (MUFA)-rich and n-6 polyunsaturated fatty acid (n-6 PUFA)-rich vegetable oils are increasingly used as fish oil replacers for aquafeed formulation. The present study investigated the fatty acid metabolism in juvenile European sea bass (Dicentrarchus labrax, 38.4 g) fed diets containing fish oil (FO, as the control treatment) or two different vegetable oils (the MUFA-rich canola/ rapeseed oil, CO; and the n-6 PUFA-rich cottonseed oil, CSO) tested individually or as a 50/50 blend (CO/ CSO). The whole-body fatty acid balance method was used to deduce the apparent in vi ...Daha fazlası

The Recent Advances to Increase Nutrient Utilization of Dietary Plant Proteins by Enzyme Supplementation and Fermentation in Rainbow Trout (Oncorhynchus mykiss): A Review

KENAN ENGİN | CAFER ERKİN KOYUNCU

Aquaculture is the fastest growing animal production sector globally. However, its sustainability heavily relies on the development of nutritionally balanced cost-effective and environmentally friendly aqua feeds for fish and crustacean species that are already being farmed or the candidate species for intensive farming in the future around the world. Therefore, feeds produced for farmed aquatic species should be highly digestible in terms of nitrogen and phosphorous contents in order to avoid excessive release of these nutrients into the water column through solid and soluble discharge. Exces ...Daha fazlası

Potential of Cottonseed Oil as Fish Oil Replacer in European Sea Bass Feed Formulation

KENAN ENGİN

Triplicate groups of 20 European sea bass (35 g) were fed five diets in which the added lipid was 100% fish oil (FO), 40% (CSO40), 60% (CSO60), 80% (CSO80) and 100% (CSO100) refined cottonseed oil (CSO), for a period of 120 days. Overall fish growth, feed conversion ratio and protein utilization were unaffected by dietary treatment, but hepatosomatic and visceral fat indexes increased with increasing dietary CSO. Fillet fatty acid composition of total lipids reflected the fatty acids in the test diets. The monounsaturated fatty acids were significantly higher in fillet of fish fed diet FO, CSO ...Daha fazlası

The effects of combined use of soybean extract and mixture of several plant oils on the growth parameters and wholebody and tissue amino acid and fatty acid compositions in juvenile Nile tilapia (Oreochromis niloticus Linnaeus 1758)

KENAN ENGİN

This study investigated the effects of combined dietary fish meal and oil replacement by soybean extract and increasing amount of plant oil mixture on growth performance, whole body and tissue amino acid and fatty acid compositions in Nile tilapia (Oreochromis niloticus). Diets in which 50% of the fish meal crude protein was replaced by soy bean extract along with 60, 80 and 100% of fish oil replacement by mixture of soy, canola and linseed oils (v/v, 1:1:1) were used in the study. Four iso-nitrogenous and iso-energetic experimental diets were prepared and fed to juvenile Nile tilapia (25 fish ...Daha fazlası
