Megjegyzések:Nano-selenium (SeNPs) has emerged as a promising dietary supplement due to its high bioactivity and potential to enhance animal growth performance. This study evaluated the effects of different concentrations of red and grey selenium nanoparticles on body weight (BW), body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) in adult Japanese quails. Quails were allocated into five groups: a control group (C0), red SeNPs at 0.5 ppm (T1) and 5 ppm (T2), and grey SeNPs at 0.5 ppm (T3) and 5 ppm (T4). Body weight and feed intake were recorded weekly over a 5-week period. BWG and FCR were subsequently calculated. Statistical analysis was conducted using ANOVA to determine treatment effects. Significant differences (P < 0.05) were observed in final BW among treatments. Both T1 (red SeNP 0.5 ppm) and T3 (grey SeNP 0.5 ppm) exhibited significantly higher BW compared to the control group. T1 achieved the highest BWG (15.13 g), while T3 also showed notable improvement (4.61 g) compared to the control (-7.80 g). The high-dose grey group (T4) showed a limited increase in BWG (0.60 g), suggesting a possible dose-dependent effect. Feed intake varied slightly among groups without significant differences, while FCR was markedly improved in T1 (1.12) and T3 (3.63) compared to the control (-2.21). Low-dose supplementation with both red and grey SeNPs positively impacted growth performance in Japanese quails. While red SeNPs at 0.5 ppm (T1) demonstrated the best results, grey SeNPs at the same dose (T3) also significantly improved BW and FCR, although to a lesser extent. The reduced efficacy observed at the higher grey SeNP dose (T4) may suggest an optimal dose threshold beyond which SeNPs could lose their beneficial effect. These results highlight the importance of nanoparticle type and concentration in modulating physiological responses and feed efficiency. Dietary supplementation with low concentrations of red and grey SeNPs enhances growth and feed conversion efficiency in Japanese quails. Optimizing the form and dose of nano-selenium could support sustainable poultry production systems.

Cím:Comparative Study of Red and Grey Selenium Nanoparticles on Organ-Specific Selenium Deposition and Growth Performance in Japanese Quails / Aya Ferroudj, Arjun Muthu, Daniella Sári, Gréta Törős, Áron Beni, Levente Czeglédi, Renáta Knop, Hassan El Ramady, József Prokisch

Megjegyzések:Selenium (Se) is an essential trace element required for various physiological functions in agriculture. Nanotechnology is applied to produce selenium nanoparticles (SeNPs) that offer new advantages, enhancing their bioavailability and reducing toxicity. To further improve the stability of Se nanoelements in the poultry industry, the grey form of Se was recently offered as a potential alternative. However, its impact on bioaccessibility, metabolism, and overall animal efficiency remains undetermined. This study investigates the impact of red and grey SeNPs on Se content in the liver, blood cellular fraction (BCF), kidney, testis, and eyes, as well as the feed intake (FI) and growth performance, of adult Japanese quails. Adult quails were randomly assigned to five groups: a control (C0) and four groups receiving either red or grey Se nanoparticles (SeNPs) at 0.05 or 0.5 mg/kg, in addition to the basal diet which already contained 0.042 mg/kg Se from the premix, resulting in total Se contents of approximately 0.092 and 0.542 mg/kg in the treatment groups (T1?T4), with four replicates per group. The growth performance of quails fed with nano-Se-supplemented diets showed significant variation across groups (p < 0.05), with body weight differing by up to 20% between the highest performing group (T2) and the lowest (T1). FI showed no significant differences across groups. The results indicated that Se accumulation differed significantly between treatments. The selenium levels in the liver increased in a dose-dependent manner, with the highest accumulation observed in T4 (0.5 mg/kg grey SeNPs), at 42% above control levels. This pattern suggests that the liver is a primary organ for selenium storage and metabolism. The greatest Se content in BCFs was recorded in the groups that received grey selenium (T3 and T4) and red selenium at high concentrations (T2), while the group given red selenium at low concentrations (T1) and the control (C0) had the lowest Se accumulation. In the kidney tissues and testis, the Se content exhibited no significant differences between the treated groups and the control. The observed variations in the eye and breast muscle Se content among treatment groups reflect the differences in selenium bioavailability, metabolism, and tissue-specific regulatory mechanisms. These findings demonstrate that grey SeNPs can significantly elevate Se bioavailability in quails, particularly in target organs, and enhance the growth performance without notable changes in feed intake. This highlights the potential of SeNPs in enhancing quail nutrition, although further research is needed to establish optimal dosing strategies for safe, effective use.

Cím:Pleurotus ostreatus Mushroom As a Sustainable Feed Supplement Promoted Growth and Immune Function in Male Japanese Quails (Coturnix japonica). / Gréta Törős, Gabriella Gulyás, Renáta Knop, Csaba Szabó, Gebrehaweria K.

Megjegyzések:The increasing threat of antibiotic resistance in poultry farming necessitates sustainable and environmentally friendly alternatives to conventional growth promoters. This study explores the use of Pleurotus ostreatus (oyster mushroom) powder-based supplements (OMPs) as eco conscious functional feed additives for Japanese quails (Coturnix japonica). Pleurotus ostreatus is a widely available, renewable resource that can be cultivated on agricultural byproducts, supporting circular economy principles and reducing environmental impact. Three OMP variants - freeze-dried fruiting bodies (OMP-TF), cooked centrifuged solid residue (OMP CSR), and liquid fraction (OMP-CL) - were evaluated against positive (?-glucan) and negative (basal diet) controls over 28 days. An immune challenge with Escherichia coli LPS was applied to assess immunomodulatory effects. Supplementation with OMPs significantly enhanced growth performance and immune response, with increased body weight gain and elevated cytokine levels (IL-1?, IL-2, IL-4), indicating improved health resilience. Biochemical analyses showed favorable liver and protein markers. Utilizing a sustainable, fungal-based feed additive derived from agricultural waste streams offers a promising, environmentally responsible strategy to reduce antibiotic usage, promote animal welfare, and support sustainable poultry production systems. These findings underscore the dual benefits of Pleurotus ostreatus supplementation in enhancing poultry health while contributing to ecological sustainability

Cím:Pleurotus ostreatus Mushroom : A Promising Feed Supplement in Poultry Farming / Gréta Törős, Hassan El-Ramady, Áron Béni, Ferenc Peles, Gabriella Gulyás, Levente Czeglédi, Mahendra Rai, József Prokisch

Megjegyzések:Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm mushrooms are cultivated on diverse by-products based on substrates that hold promise for mitigating antibiotic usage in the poultry industry and reducing environmental pollution. By incorporating agricultural by-products into mushroom cultivation, the functionality of the mushroom products can be increased, then the final product can be a more effective feed supplement. After mushroom cultivation, spent mushroom substrate (SMS) can be valorized, due to the presence of huge amounts of bioactive compounds like beta-glucan, chitin, polyphenols, and flavonoids related to mycelia. As a prebiotic and antimicrobial feed supplement, these mushrooms positively influence gut microbiota, intestinal morphology, and thus overall poultry well-being. This article underscores the potential of solid-state fermentation (SSF) to enhance the bioactivity of oyster mushrooms and their derivatives, offering a cost-effective and efficient strategy for transforming unconventional feeding materials. Moreover, it emphasizes broader implications, including the reduction of antibiotic dependence in poultry farming, highlighting the promising integration of oyster mushrooms and their derivatives for sustainable and environmentally conscious poultry production.
