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

EKOLOJİK SU ÜRÜNLERİ YETİŞTİRİCİLİĞİ

MURAT BİLGÜVEN

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. Geleneksel tarım yöntemlerinin uygulandığı sanayileşmiş birçok Avrupa ülkesinde, ekolojik denge alt üst olmuş, buna bağlı olarak insan sağlığı bozul¬muş, birçok canlı türünün nesli tükenme tehlikesiyle karşı karşıya kalmıştır. Çiftçiler ve tüketiciler, geleneksel tarım uygulamalarında (bitkisel ve hayvansal üretim) kull ...Daha fazlası

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

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

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

EKOLOJİK SU ÜRÜNLERİ ÜRETİMİ

MURAT BİLGÜVEN

Yirminci yüzyılın ikinci yarısında yaşanan hızlı sanayileşme ve nüfus artışı, çevre sorunları yanında, artan nüfusun yeterince beslenememesi yani açlık sorunun ortaya çıkmasına neden olmuştur. Artan nüfusun beslenme gereksinimi, insanoğlunu tarımda birim alandan; maksimum ürün almaya yöneltmiştir. Birim alandan yüksek verim almaya yönelik yoğun ve bilinçsiz tarım ilacı ve gübre kullanılması ve sonuç olarak, bu kimyasalların tarımsal ürünlerde oluşturduğu ve yeraltı sularına karışarak içme sularında yarattığı kalıntılar, insan sağlığını ve yaşamını tehdit etmeye başlamıştır.

Changes in Liver Tissue Trace Element Concentrations During Hepatitis B Viral Infection Treatment

FAHRİ KARAYAKAR | TAHSİN ÇOLAK

Approximately 350–400 million people in the world have Hbs Ag (hepatitis B virus surface antigen) positivity. In the international guidelines, the permanent suppression of replication in chronic hepatitis B virus (HBV) infection therapy is reported as the primary therapeutic goal. Trace elements play a key role in liver diseases. The aim of our study is to determine some trace element concentrations in the liver during HBV treatment periods. The measurement of 11 trace elements (manganese, lead, nickel, chromium, cadmium, iron, copper, zinc, silver, cobalt, and aluminum) was carried out by the ...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
