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

Accumulation and Elimination of Cadmium by the Nile Tilapia (Oreochromis niloticus) in differing Temperatures and Responses of Oxidative Stress Biomarkers

FAHRİ KARAYAKAR | BEDİİ CİCİK

The aims of this study were to investigate the accumulation (15 days) and elimination (15 and 30 days) of cadmium (Cd) in the liver, gill, kidney and muscle of Oreochromis niloticus following exposures to different concentrations (1 and 2 mg/L) of Cd at different water temperatures (20, 25, 30 o C). Additionally, responses of oxidative stress biomarkers (superoxide dismutase, SOD; catalase CAT; glutathione peroxidase, GPx and malondialdehyde, MDA) of the liver were determined following Cd exposures. In accumulation period, Cd levels increased significantly in all the tissues at all temperature ...Daha fazlası

Tarımsal üretimde bugüne kadar ana hedef genellikle üretim artışı ol¬muştur. Kantitatif üretim artışının yanında, ürün kalitesinin artırılması, üretim girdilerinin azaltılması, doğal kaynakların korunması, insan, hayvan ve çevre sağlığı gibi konular hep ikinci planda kalmıştır.

Effects Of The Feeds Containing Different Plant Protein Sources On Growth Performance And Body Composition Of Rainbow Trout (Oncorhynchus mykiss W )

MURAT BİLGÜVEN | MUSTAFA BARIŞ

In this study, a total of 720 rainbow trout (Oncorhyncus mykiss) having 50.08±0.19 g of average initial weight were used to compare of usage of the soybean meal, sunflower meal, canola meal and cottonseed meal as the best plant protein source. Four different feeds which contain soybean meal (SBM), canola meal (CM), sunflower meal (SFM) and cotton seed meal were used, respectively. Four trial groups were tested in triplicate during 12 weeks. Experimental diets were prepared as isonitrogenous significantly difference among the groups for average feed consumption, condition factor and survival ra ...Daha fazlası

Heavy metal levels in economically important fish species sold by fishermen in Karatas (Adana / TURKEY)

FAHRİ KARAYAKAR | UMUT IŞIK | BEDİİ CİCİK

In this study, heavy metal (Cu, Zn, Cr, Cd, Pb and As) levels in the muscle of economically important fish species (Trachurus mediterraneus, Sparus aurata and Pegusa lascaris) living in different water columns in the North-East Mediterranean Sea were measured. Fish were bought from local fishermen between September 2016-August 2017 in Karatas¸ region (Adana, Turkey). Levels of Cd, Cr, Pb and As were highest in the muscle of T. mediterraneus, S. aurata and P. lascaris in the autumn season, while Cu levels were highest in T. mediterraneus and S. aurata in the spring season. The lowest and highes ...Daha fazlası

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

Prophylactic efect of myricetin and apigenin against lipopolysaccharide‑induced acute liver injury

FAHRİ KARAYAKAR | FERBAL ÖZKAN YILMAZ | ARZU ÖZLÜER HUNT

Background Liver has an important role in the initiation and progression of multiple organ failure that occurs in sepsis. Many natural active substances can be used to reduce the liver injury caused by sepsis. For this aim, the efects of myricetin and apigenin on mice model of acute liver injury was evaluated in this study. Methods and results Thirty-six mice were randomly divided into six groups as; control, lipopolysaccharide (LPS) (5 mg/kg), LPS+myricetin (100 mg/kg), LPS+myricetin (200 mg/kg), LPS+apigenin (100 mg/kg), and LPS+apigenin (200 mg/kg) groups.

The effects of fish meal replacement by yeast based nucleotides on growth body composition and digestive enzyme activity in rainbow trout juveniles Oncorhynchus mykiss

ARZU ÖZLÜER HUNT | Ferbal Özkan Yılmaz | Kenan Engin | Serap Yalın | Nefise Özlen Şahin

This 60 day study investigated the effects of organically certified nucleotide yeast-derived protein source (Nu-Pro®) on growth, feed efficiency, fillet proximate composition and digestive enzymes in rainbow trout (Onchorhyncus mykiss). Diets were isonitrogenous and isocaloric. Three experimental diets wherein 20%, 40% and 60% of the fish meal content was replaced by Nu-Pro®, were compared to the control diet in which the crude protein content was anchovy fish meal and corn gluten meal. The rainbow trout (initial weight 27 g/fish) were fed twice daily in 200-l Aqaria. Live weight gain increase ...Daha fazlası
