The biochemical analysis of fish tissue is considered a dependable indicator of the fish's quality, nutritional content, physiological condition, and environmental habitat. Alosa immaculata (Bennett, 1835) is a migratory fish species with great ecological and economic importance, which undergoes a remarkable journey during its migration. As A. immaculata embarks on its migration, the dynamic biochemical changes in its meat composition offer valuable information that contributes to a comprehensive understanding of the species' adaptation to the challenges posed by migration. In this context, this study aimed to investigate the meat biochemistry of Pontic Shad during the period of migration from three different points: Station 1 - Saint Gheorghe Branch, Station 2 - Sulina Branch, and Station 3 – Brăila, km 169 and km 197 of the Danube River. Significant differences (p<0.05) were recorded in the level of water, lipid, and ash, while no differences were recorded in the level of proteins (p>0.05). Notably, the lipid content in the meat samples from the Sulina exhibited the highest percentage, while the protein content in the samples from the St. Gheorghe arm surpassed that of the Sulina and Brăila, indicating differences in nutritional profiles that could be attributed to physiological adaptations during migration.

Certified traditional products are an essential part of every country's cultural and gastronomic heritage. The quality and authenticity of these products are ensured by the authentic ingredients and artisanal methods of preparation. Consumers' growing interest in healthy eating makes the certification of traditional products a necessity. In this study, we have carried out a comprehensive statistical analysis of the current number of food products certified under quality schemes such as PDO, PGI, TSG, and also labelled as 'Traditional Product' and 'Traditional Romanian Recipe', both in Romania and in the European Union (EU). We also looked in detail at the current number of dairy products certified according to these standards. The data were obtained from the EU's eAmbrosia electronic register and the Ministry of Agriculture and Rural Development's CPAC electronic catalogue. The results provide a valuable and up-to-date perspective on certified and labelled food products, contributing to the development and promotion of the gastronomic heritage in Romania and the EU.

This study aimed to evaluate the influence of the protein level from fish feed on the growth dynamics, hematological profile, and meat biochemical composition of juvenile European catfish, Silurus glanis (Linnaeus, 1758). In this context, 508 juvenile European catfish, with an average weight of 33±1.80 g/fish, were reared in a recirculating aquaculture system (RAS). Fish were fed with two different proteins: VE 41- fish feed with 41% protein content, and VE 50- fish feed with 50% protein content. After 35 days, the results regarding the growth performance revealed a better feed conversion ratio (FCR-1.03 g/g) and specific growth rate (SGR - 2.02 %/day) in the VE50P. Also, fish meat's hematological profile and biochemical composition showed a similar trend. In conclusion, the fed protein content plays an essential role in the digestibility and efficiency of nutrient utilization, on the welfare and nutritional quality of the final product.

Three different LED light colors were applied during Gerze local Turkish chicken egg incubation. Red, green, and white colors were used each containing 160 eggs for 18 days. Eggs were individually weighed at the onset of incubation and during transfer to the hatchery. Lighting was not applied in the hatchery and chicks were hatched in darkness. Total egg weight loss of incubation was 10.45%, 9.43% and 8.90% for red, green, and white led groups and the differences were significant (P<0.05). Fertility between light-color groups was insignificant. The red light group had the highest hatchability (82.64%) in fertile eggs, while the green and white groups had 81.72% and 67.67% respectively. While the egg weight differences between light groups were insignificant; the highest chick weight was obtained in the green light group (P<0.05). The white LED color delayed the hatching time of the chicks. All hatched chicks were scored according to Pasgar Scoring. The scores of chicks were 9.68, 9.62, and 9.71 for the red, green, and white lighting groups’ chicks.

This study aimed to investigate the effect of light intensity on the growth performance, hematological profile, and biochemical composition of muscle tissue of paddlefish juveniles, reared in a recirculating aquaculture system (RAS). Two experimental variants were created: V1- where the rearing units have green color, and the average of the light intensity was 105 lx (mean fish weight was 21.65 ± 0.6 g), and V2- where the rearing units have white color, and the average of the light intensity was 30 lx (mean fish weight was 22.15 ± 0.8 g). Fish were fed at an intensity of 2.5% BW for 48 days. Growth of juvenile paddlefish under 30 lx was significantly better than that of paddlefish under 105 lx (p < 0.05), as indicated by final weight (1158.20 ± 21.90 g), specific growth rate (2.18% ± 0.07%/day) and feed conversion coefficient (0.80 ± 0.28 g/g). In conclusion, the paddlefish juveniles can adapt to various light intensities and grow favorably under low light conditions in a recirculating aquaculture system.

This study was executed to determine the effect of selection in live weight on reproduction of chickens. A total 300 Turkish local Gerze chickens were used in the study. All chickens were individually weighed at 8 weeks of age. Heaviest 75% (225 chickens) were chosen and separated from the flock. The mean live weight of chosen birds was 404.34 gram at 8 weeks and significantly higher than unselected birds (359.29 gram; P<0.05). At 18 weeks of age, the chickens were weighed again. The selected group had reached 1068.92 grams while unselected chickens 1059.69 grams and the difference between them was insignificant. Age at first egg was 182 days for selected hens while 177.5 days for unselected hens. The mean egg weights of eggs produced until 40 weeks of age were 47.11 g and 46.76 g, respectively for selected and unselected groups.

This work aims to investigate Wet-Aging with Vitamin C on chemical properties of Biceps femoris muscles collected from sustainable management of Cervus elaphus L. population from Northern Eastern Carpathians, Romania. 2% Alkaline Vitamin C Powder per 0.520 kg muscle sample, 4% Alkaline Vitamin C Powder per 0.504 sample kg, and 6% Alkaline Vitamin C Powder per 0.496 kg sample were used. Samples were protected from light and kept at 2°C for 10 days in order not to accelerate oxidative stress of the muscle samples. The influence of Vitamin C used in the wet-aging method was tested by performing quality biomarkers analyses. Data distribution was evaluated using SPSS Statistics 26.0 software. Non-parametric Independent Samples Kruskal-Wallis test was performed to analyze how the percentage of protein, water, collagen, and fat varied with the concentration of vitamin C in muscle samples. The results suggest that there are significant differences for quality biomarkers (***p < 0.001) in the percentage of fat, water, protein, and collagen in particular, between the percentages of 4.00 % and 6.00% Vitamin C introduced. Bonferroni correction was applied to counteract errors for multiple assays and to reduce the chance of an erroneous conclusion.

Due to the customers' desire to improve their healthy diet enriched in Omega-3, researchers included ingredients such as flaxseed in poultry feed. The study was conducted on a commercial farm to compare the organoleptic qualities of broilers’ meat using dietary flaxseed and alfalfa. The broilers (44.000 heads) divided into two groups (C, E) were fed with compound feed containing 6% flaxseed + 2% alfalfa (growth phase) and 12% flaxseed + 2% alfalfa (finishing phase). At the end of the experiment, the organoleptic and physico-chemical (color and pH) meat parameters of breast and thigh were assessed for storage period (24, 48, 72 and 168 h). The results showed no significant differences (p≥0.05) concerning the pH of the thighs and breast, but significant differences (p≤0.05) were observed for all color parameters (L*, a*, b*) within the storage period*group interaction. In conclusion, using combined dietary rich Omega-3 sources (flaxseed) and xanthophyll (alfalfa) contributes to meat quality enrichment by increasing the beneficial fatty acid concentration and meat color, important criteria in customer decision.
