Background and Aim: Poultry meat is an excellent animal protein source accessible to many low-income families in developing countries. It is also part of a balanced diet and contains valuable nutrients necessary for maintaining human health. The poultry sector implements improved processes to increase the quality and nutritional value of poultry meat. This study aimed to determine the influence of licorice root extract on the amino acid, fatty acid, vitamin, mineral composition, nutritional value, and productivity of quail meat. Materials and Methods: Two groups were formed from Japanese quails: A control group and one experimental group, each consisting of 50 individuals. Quails from both the experimental and control groups received the same complete diet. Quails in the experimental group had licorice root extract added to their water at a dosage of 10 g/L, starting from the age of 3 days to 42 days of growth. At 42 days of age, 30 birds from each group were slaughtered to examine their meat productivity and chemical composition. The quail carcasses were analyzed for the following parameters: Live weight, carcass weight, nutritional value, mineral substances, vitamin content, fatty acid composition, amino acid composition, and amino acid score. Results: This study demonstrated that quails in the experimental group receiving water with licorice extract exhibited higher indicators than those in the control group. Calcium (21.05%), magnesium (20.83%), and phosphorus (23.53%) were the most elevated mineral substances in the meat of the experimental birds. Vitamins E (22.22%) and C (20.0%) showed the greatest increase in vitamin content. The fatty acid composition parameters 17:0 margaric acid (8.16%), 18:3 linolenic acid (6.25%), and 20:4 arachidonic acid (4.49%) showed the highest increase. There was a clear increase in the amino acids valine (4.61%), lysine (4.32%), threonine (5.99%), tryptophan (4.87%), phenylalanine (5.87%), and cysteine (14.17%). The application of licorice root extract also positively impacted the amino acid score of quail meat, except for leucine, which remained within the range compared with the control group. Quails in the experimental group weighed 7.96% more live weight before slaughter than the controls. Moreover, the carcass weight was in favor of the experimental group (8.59%). Conclusion: The use of licorice root extract positively influences the quality and biological value of quail meat. Data on amino acids, fatty acids, vitamins, trace elements, and other important components of quail meat will significantly expand our understanding of the biological value of licorice root extract. These findings can be used in the formulation of balanced diets for children and adults and highlight the importance of this issue.

Introduction: Aquaculture is globally recognized as an effective means of supporting economic growth and livelihood security. However, the sector continues to fall short of projected production targets due to the use of low-quality inputs and inadequate culture techniques. The use of probiotics in aquaculture has been proposed as a nutritional strategy to enhance fish growth and immune responses. This study investigated the effects of dietary supplementation with a multistrain probiotic combination—Leuconostoc mesenteroides and Lactococcus lactis—on growth performance, immune parameters, and gut microbiota in African catfish (Clarias gariepinus).Methods: Fish were fed either a basal diet or an experimental diet containing L. mesenteroides a 95 nd L. lactis at 10⁶ CFU/g for 8 weeks.Results and discussion: The probiotic-supplemented group showed significant improvements in feed utilization, alternative complement pathway activity, lactic acid bacterial populations, mucus secretion, and peroxidase activity compared with the control group (p < 0.05). Serum lysozyme activity was also significantly higher in the probiotic-fed group. Furthermore, fish receiving the supplemented diet exhibited superior growth metrics, including weight gain, final body weight, and specific growth rate (p < 0.05). Enhanced superoxide dismutase activity was also observed in the probiotic group. These results suggest that dietary inclusion of L. mesenteroides and L. lactis may serve as an effective immunostimulant feed additive for African catfish aquaculture.

The ban on antibiotic growth promoters in livestock has intensified the search for effective probiotic alternatives. This study assessed the impact of a novel probiotic cocktail—comprising Lactobacillus plantarum AMT14 and AMT4, L. rhamnosus AMT15, and Bifidobacterium animalis AMT30—on the serum metabolome of lambs using an untargeted GC/MS approach. Sixteen Kamieniec lambs were divided into control and probiotic groups, with serum collected on days 0, 15, and 30. Metabolomic profiling revealed significant alterations in lipid and amino acid metabolism in the probiotic group. By day 15, 38 metabolites were upregulated, including 9,12-octadecadienoic acid, arachidonic acid, and cholesterol. On day 30, key increases included D-glucose, oleic acid, glycine, decanoic acid, and L-leucine. Multivariate analyses (PCA, PLS-DA) demonstrated clear separation between groups, and ROC analysis identified strong biomarkers with high predictive accuracy. These results suggest that probiotic supplementation can beneficially modulate host metabolism, potentially enhancing immune and physiological function in lambs. This highlights the value of multi-strain LAB-Bifidobacterium probiotics as a promising strategy for improving health and reducing antibiotic reliance in ruminant production systems.

В статье представлены результаты исследования кобыльего молока на свежесть и безопасность с использованием общепринятых органолептических и физико-химических исследований. Материалом для наших исследований служили пробы кобыльего молока (n=45), отобранных из к/х Алматинской области.

The use of aquaculture feed ingredients based on wild fish capture is an ecological concern since it leads to natural habitat destruction and loss of biodiversity. Addressing this concern, black soldier fly larvae meal (BSFLM) has been suggested as a promising alternative ingredient to replace fish meal. To date, the advantages and disadvantages of BSFLM as an alternative ingredient for different aquaculture species have been extensively investigated. However, its impacts on closed aquaculture systems, like aquaponics, particularly on water quality, plant growth and elemental dynamics, have not been researched extensively. Therefore, a 56-day feeding trial on the substitution of conventional fish meal with BSFLM at inclusion rates of 5, 10 and 15% on the performance of Micropterus salmoides (18.58 ± 2.86 g) and aquaponic system was conducted. The results showed that fish weight gain and plant ( Lactuca sativa ) yield were optimal at the 5% inclusion level but decreased at the 10 and 15% levels of BSFLM inclusion in the diet. The latest water quality parameters led to a decrease in ammonia and phosphorus levels by 15% BSFLM in the diet. The macro-mineral (Ca, Mg, K) utilisation efficiency decreased with increasing BSFLM levels, while trace minerals (Zn, Cu, Fe) were more effectively utilised at 5% inclusion. Most LCA impact categories increased with increasing levels of BSFLM in diet, mainly caused by the electricity and water demand and composting-related nitrogen emissions of BSFLM production. Findings suggest that a moderate 5% BSFLM inclusion is optimal for aquaponic system performance.
