Ammonia is a critical hazardous nitrogen metabolic product in aquaculture. Despite trials for its control, ammonia intoxication remains one of the most issues to overcome. In this study, we explored modulatory effect and potential mechanism by which Yucca schidigera extract (YSE) can ameliorate intoxication-induced adverse effects on tilapia health metabolism. A total number 120 Nile were evenly assigned into four groups with three replicates each. The first group served as normal control...
Fatty liver injury is a prevalent condition in most farmed fish, yet the molecular mechanisms underpinning this pathology remain largely elusive. A comprehensive feeding trial spanning eight weeks was conducted to discern potential of dietary chitosan mitigating deleterious effects high-fat diet (HFD) while concurrently exploring underlying mechanism. Growth performance, haemato-biochemical capacity, antioxidant apoptotic/anti-apoptotic gene expression, inflammatory and histopathological...
Abstract This study was performed to reveal the metabolic effects and molecular mechanisms that govern dietary incorporation of clenbuterol on growth performance, haemato-biochemical changes, histological alteration, gene expression regulating glucose lipid metabolism in normal high-fat diets fed Nile tilapia ( Oreochromis niloticus ). Six experimental were formulated, incorporating different concentrations clenbuterol. The 1st three groups supplemented with a diet comprising 6% fat, 0, 5,...
Abstract The danger posed by waterborne toxicity from herbicides endangers the aquatic ecosystem. Using dietary medicinal herbs is a useful approach to mitigate effects of herbicide on animals. This study attempts examine consequences and potential mechanisms behind addition horseradish tree ( Moringa oleifera ) leaf extract (MOLE) with help phytase check overall growth performance, biochemical changes, histological alteration, gene expression in normal after glyphosate challenge Nile...
Fenugreek seed (FS) contains abundant functional biomolecules that activate the antioxidative and immunity system of aquatic animals. In this study, methanolic extract FS was included in Nile tilapia diets at 0, 0.05, 0.1, 0.15, 0.2% levels fed to fish for 90 days. (10.57 ± 0.14 g) were randomly divided into five triplicate groups check growth performance, haematobiochemical profile, immunity, response, tolerance Aeromonas hydrophila infection. The results revealed significantly improved...
The present study evaluated the enhancement of growth rate, intestinal health, immune-related genes, and resistance against suboptimal water temperature in common carp (2.01 ± 0.02 g) by dietary paraprobiotics. Fish were fed heat killed Lactobacillus plantarum (LP20) at 0 (control), 50, 100 mg/kg for 2 months. After feeding trial fish exposed to averaged 13.22 0.44 °C 48 h. final body weight, weight gain, specific feed conversion ratio LP20 significantly enhanced (P < 0.05). villi length...
This study assessed the impact of dietary supplementation single- and multi-strain Bacillus-based probiotics on growth performance, intestinal morphometry, blood parameters, immune-oxidative status transcriptomic response Nile tilapia for 60 days. Fish (N = 150, 1.632 ± 0.035 g) were allocated into five experimental groups: (1) Control group (CG) that was fed a basal diet; (2) Eco. 0.01%, received diet with 0.1 g/kg Ecobiol; (3) 0.02%, 0.2 (4) Pro-F FMC 0.001%, 0.001 Sanolife PRO-F FMC; (5)...
The present study evaluated the possible synergistic impacts of sodium butyrate and Spirulina platensis as a feed additive on growth performance, carcass composition, blood health, intestinal histomorphology Nile tilapia (Oreochromis niloticus). A control three treated diets were supplemented with (SB) 350 mg, (SP) 1g mixture mg SB SP/kg diet (SB/SP) respectively, fed for monosex (12.5± 0.50 g, n=120) two months. results revealed higher performance (final weight, weight gain, gain rate, SGR...
Olive leaves are an immense source of antioxidant and antimicrobial bioactive constituents. This study investigated the effects dietary incorporation olive leaf extract (OLE) on growth performance, hematobiochemical parameters, immune response, defense, histopathological changes, some growth- immune-related genes in common carp (Cyprinus carpio). A total 180 fish were allocated into four groups with triplicate each. The control group received basal diet without OLE, while other three fed a...
The ameliorative effects of Spirulina and Saccharomyces cerevisiae (S. cerevisiae) against fipronil toxicity in Nile tilapia fish were investigated. Fipronil is a kind pesticide that widely used agriculture, thus this trial was conducted to evaluate the effect on growth related parameters (final body weight, feed intake, weight gain, conversion ratio, specific rate, protein efficiency ratio), hematology (RBCs, WBCs, hemoglobin, packed cell volume, deferential leukocytic count), biochemistry...
Abstract The current study investigated how different fasting and refeeding regimes would impact Nile tilapia growth performance, histopathological examination, gene expression of myostatin, myogenin, GH , IGF-1 NPYa . fish ( n = 120) were randomly allocated into four groups, including the control group fed on a basal diet for 6 weeks (F6), A starved 1 week then refed 5 (S1F5), B 2 4 (S2F4), while C (S4F2). Fasting provoked decrease in body weight coincided with more extended starvation...
Abstract The antioxidant and detoxification systems involve intricate pathways in which nuclear factor erythroid 2-related 2 (Nrf2) Kelch-like ECH-associated protein 1 (Keap1) play pivotal roles. In the basal state, reactive oxygen species are generated neutralized a balanced manner. However, stressors can disrupt this equilibrium, resulting oxidative stress cellular damage. study, we analyzed expression of nrf2 keap1 Nile tilapia ( Oreochromis niloticus ) under homeostasis challenge with...
The present study investigated influence of Yucca schidigera extract (Ys E) on the growth performance, hepato-renal function, antioxidative status and histopathological alterations in Nile tilapia (Oreochromis niloticus) exposed to hypoxia stress. 120 fish (42.39 ± 1.25 g) were distributed into four equal groups, where group (a) kept as a control group, (b) supplied with YsE (8 mg/L water every 2 days), (c) after weeks from start experiment (d) provided for then hypoxia. treatments conducted...
