the present study was carried out to evaluate the effects of dietary nano-structured zeolite (nz) levels on reduction of aflatoxin b1 (afb1) in the diet of rainbow trout (oncorhynchus mykiss) for 56 days. for this purpose, 270 fish (23 ± 3.7 g) were randomly distributed into 6 groups including c (control), nz0.5 (basic ration + 0.5 % nano-structure zeolite), nz1 (basic ration + 1 % nano-structu...

The objective of this research was to evaluate yield parameters (gained weight, weight percentage, survival, feed conversion factor (FCR), feed conversion efficiency (FCE), condition factor (K), specific growth rate (SGR) and hepatosomatic index (HSI) of trouts fed with experimental diets elaborated with bean (Phaseolus vulgaris L.) flour instead of fishmeal with 15, 30 and 45% (BF15, BF30 and ...

The main objective for the present research is to assess effect of cyclic starvation and L- carnitine supplementation on growth (body final weight, hepatosomatic index (HSI), daily growth rate (DGI), feed conversion ratio (FCR) and voluntary feed intake (VFI)), body compositions (crude protein, crude lipid, ash and moisture), biochemical (plasma total protein, glucose, cholesterol, triglyceride...

The objective of this research was to evaluate yield parameters (gained weight, weight percentage, survival, feed conversion factor (FCR), feed conversion efficiency (FCE), condition factor (K), specific growth rate (SGR) and hepatosomatic index (HSI) of trouts fed with experimental diets elaborated with bean (Phaseolus vulgaris L.) flour instead of fishmeal with 15, 30 and 45% (BF15, BF30 and ...

Atlantic salmon (Salmo salar) are endangered anadromous fish that may be exposed to feminizing endocrine disrupting compounds (EDCs) during early development, potentially altering physiological capacities, survival and fitness. To assess differential life stage sensitivity to common EDCs, we carried out short-term (4 day) exposures using three doses each of 17 α-ethinylestradiol (EE2), 17 β-est...

A high intake of carbohydrates, associated with obesity, is one of the major causes of fatty liver disease in humans. This study investigated how high carbohydrate intake induces fatty liver disease in Blunt snout bream (Megalobrama amblycephala). Blunt snout bream were fed a high-carbohydrate diet (HCBD) for 60 days. Their growth indices were evaluated, and the transcriptomes, metabolites, bio...

This study investigated the effect of different dietary selenium (Se) sources on growth performance, antioxidant capacity, gut microbiota, and molecular responses Pacific white shrimp Litopenaeus vannamei. Four Se (sodium selenite, L-selenomethionine, yeast, or nanoparticles) were added to purified diets 0.4 mg Se/kg diet for ( 1.60<...

In this study, three growth trials were conducted to check the efficacy of poultry corn by-product meal, which was a combination wet processing waste and that co-dried. It relatively new product, its first trial in laboratory (aquarium study) evaluate substitution whole meal with plus (PCBM) practical diets for channel catfish. (84 days culture period), 7 levels PCBM (0, 5, 10, 15, 20, 25 30%) ...

The present work investigated how the combination of poultry oil with microalgae oils, rich in eicosapentaenoic acid and docosahexaenoic (ED diets) or n-6 docosapentaenoic n-3 (DD modulates hepatic lipid metabolism gilthead sea bream juveniles. Diets were tested using two different fishmeal contents (15% 7.5%) compared against a fish oil-based diet (CTRL) negative control diets based on as sour...
