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:Spectroscopic characterization of nano-selenium and its dietary effects on quail growth and organ selenium uptake / Aya Ferroudj, Arjun Muthu, Daniella Sari, Aron Beni, Levente Czegledi, Renata Knop, Jozsef Prokisch
Dátum:2025
Megjegyzések:This study aims to characterize the spectral properties of selenium nanoparticles (SeNPs) in both red and grey forms and assess their biological impact in a real animal model. Raman spectroscopy was employed to analyze structural differences between SeNPs in solid form, while fluorescence measurements were conducted to examine the relationship between their structure and optical characteristics. Raman spectra confirmed the trigonal crystalline structure of grey SeNPs with peaks at 233.5 cm??, while red SeNPs exhibited peaks around 252.4 cm??, indicating their amorphous nature. Fluorescence analysis revealed that grey SeNPs displayed more consistent fluorescence behavior than red SeNPs, likely due to their more stable crystalline and semi-crystalline structure, in contrast to the amorphous nature of red SeNPs. To evaluate Se bioavailability and distribution, adult Japanese quails were randomly assigned to five groups: a control (C0) and four treatment groups receiving either red or grey SeNPs at 0.05 and 0.5 mg/kg (T1, T2, T3, and T4). Growth performance was evaluated by measuring body weight changes in all treatment groups for 28 days Selenium accumulation was measured in the liver, kidney, eye, testes, breast muscle, and blood cellular fraction (BCF). The results showed that the higher SeNP concentrations (0.5 ppm) improved body weight, with T2 (Red Se 0.5 ppm) showing the greatest growth, while T1 (Red Se 0.05 ppm) had the lowest body weight. These findings suggest that SeNP supplementation, especially at higher doses, can enhance growth performance in Japanese quails. Regarding the content of Se,the highest Se content was recorded in the liver in the T4 group (grey SeNPs, 0.5 ppm), whereas the control group had the lowest. In BCFs, the highest Se content was observed in T3 (grey Se 0.05 ppm), with the control group again having the lowest. Selenium levels in the kidney and testes remained stable across all groups, with no significant differences. In eye tissues, Surprisingly, the control group had the highest Se concentration, while T1 and T2 (red SeNPs) showed lower levels, and T3 and T4 (grey SeNPs) had intermediate values. In breast tissue, the highest Se content was observed in T1 (red Se 0.05 ppm), significantly differing from all other treatments, suggesting a unique distribution pattern that warrants further investigation. Overall, these findings demonstrate the tissue-specific effects of selenium supplementation, and provide insights into the bioavailability of different SeNP forms and their potential implications for health and disease prevention

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:Effects of herbal plant supplementation on immunity and antioxidant status in mid-lactation dairy cows / G. Gulyás, L. Czeglédi, M. Kokas, E. Török, L.D. Brassó, Á. Béni, A. Kiss
Dátum:2025
ISSN:0377-8401
Megjegyzések:High-yield dairy farms have maximised their productivity, which is a challenge concerning animal physiology even beyond the transition period. While several studies have verified a wide range of beneficial effects of plant essential oils during the periparturient period in dairy cows, their effects in mid-lactation are less studied. However, this period is critical for maintaining milk production and metabolic stability in high-yielding cows. The objective of the present study is to determine the effects of supplementation with herbal plants on immunity and antioxidant status in mid-lactation dairy cows. Thirty-six Holstein-Friesian cows used in this experiment were randomly assigned to 6 groups (1 control and 5 treatments, n?=?6/group). The treatments were conducted using oregano, basil, thyme, rosemary, or yarrow, while the control was exempt from any supplementation. The feeding experiment lasted 14 days. Milk samples were collected on days 1 and 14 to assess milk quality. Milk and blood samples for molecular analysis were collected on day 15, following the 14-day feeding trial. The applied herbs were standardised to two grams of essential oil/cow/day. All parameters were analyzed by a linear mixed model and expressed relative to the control group. The basil essential oil resulted in a significant increase in the total immunoglobulin level in milk, and the serum IgM level was found to be significantly higher in the rosemary. Significantly higher serum total antioxidant capacity (TAC) values were detected in the oregano, thyme, rosemary, and yarrow groups. Significant increases were observed in milk TAC for groups given oregano and thyme. The activity of the superoxide dismutase enzyme (SOD) was found to be significantly higher in the oregano group, and significantly lower C-reactive protein levels, an indicator of inflammation and oxidative stress, were measured in the oregano and rosemary groups. Of the antioxidant-related genes, a significantly higher expression of the SOD gene was detected in the oregano group, while for the glutathione peroxidase gene, significantly higher mRNA expression was observed in the oregano and thyme groups. In conclusion, our results suggest that dietary supplementation with oregano and thyme improves antioxidant status in mid-lactation dairy cows. These findings may support the development of more precisely tailored feeding protocols to enhance well-being and promote the health and performance of dairy cows during mid-lactation.

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
Dátum:2024
ISSN:2077-0472
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.
