The quality of poultry meat is largely determined by the evolution of production, breeding practices, and genetic management. Globally, the poultry meat industry has experienced remarkable expansion, continuously adapting to market requirements and sustainability standards. The genotype of the chickens plays an essential role in the quality of the meat, with the advanced selection of breeds aimed at improving the food efficiency and organoleptic qualities of the flesh. Breeding systems range from intensive to extensively organic, each of which has a direct impact on animal health and welfare, as well as on the quality of meat. Chicken feeding, adapted to the specific needs of each genotype, improves the nutritional profile of the meat, optimizing the content of essential fatty acids and micronutrients. Handling chickens, from transport to processing, is crucial for minimizing stress and preventing meat quality defects.

The objective of the current investigation was to assess the hepatoprotective capabilities of two algal species, Ulva lactuca and Spirulina platensis, in carp (Cyprinus carpio) fingerlings subjected to imazalil exposure. Consequently, the experimental groups were simultaneously exposed to the fungicide (5mg/kg feed) and provided with feed containing either Ulva lactuca alone (IMZ-Uv variants – 5 g/kg ulva), Spirulina platensis alone (IMZ-Sp variants – 5 g/kg spirulina), or a combination of both algae (IMZ-Uv-Sp variants – 2.5 g/kg ulva and 2.5 g/kg spirulina). Two control variants were employed in the experiments: a negative control receiving normal feed and a positive control receiving feed with 5mg/kg imazalil. Each variant involved 15 fish per tank, and after the experiment, five fish from each tank were utilized for biological samples. The assessment of biochemical serum parameters and oxidative stress markers for each specimen revealed that imazalil induced alterations in biochemical parameters, resulting in physiological dysfunctions in carp. However, the administration of algae, in particular Spirulina platensis, demonstrated significant potential in mitigating the adverse effects of imazalil.

One Health is connected with the One Welfare through links between animal and human welfare, and with sustainable animal-keeping systems. This connection fosters interdisciplinarity, and helps ensure human and animal wellbeing, while addressing more effectively current societal challenges in a more sustainable way. There is a knowledge gap regarding some species-specific operational welfare indicators in some aquaculture species such as crustaceans with potential to impact human wellbeing, and justifying a One Welfare approach. A review of the scientific literature based on PRISMA protocols has been carried out within this study. The review focuses on pain indicators and nociception, and the potential impact on the welfare of shellfish, as well as on the physiological and molecular mechanisms associated with the use of eyestalk ablation (EA) in adult female shrimp in aquaculture facilities. Through the One Health and One Welfare approaches, an assessment of whether the EA procedure is valid for use in shrimp management protocols was also carried out. The case study concluded that alternatives to EA should be sought to ensure compliance of this practice with the One Health and One Welfare concepts.

By its very nature, the extraction of mineral aggregates invariably has an impact, often negative, on the ecosystem where it occurs. In essence, it requires that any extraction of mineral aggregates likely to have a significant effect on protected bird species be subject to an appropriate assessment detailing this impact on them and how will align with the conservation objectives of the two Natura 2000 sites. In this article two Natura 2000 sites from Teleorman and Prahova counties (ROSPA0024 OLT-DANUBE confluence and ROSPA0152 IALOMIȚA corridor) where study considering the impact evaluation of mineral aggregates extraction on the protected bird species.

The aim of this work focused on the analysis and evaluation of the emulsion stabilizer, Na2H2P2O7 on the colorimetric profile in a meat product with a heterogeneous structure of Sus scrofa domesticus. Water (%), fat (%), protein (%), collagen (%), and salt (%) contents were also monitored. Depending on the fat and water content, the agent absorption may vary, which may affect the uniformity or intensity of the color of the finished product. The experimental samples consisted of a control batch and 0.09% Na2H2P2O7 per 3000 g of meat fed to the experimental batch. Data distribution was evaluated using SPSS Statistics 26.0 software and Graph Pad Prism 9 software. A T-test was applied to evaluate the influence of the Na2H2P2O7 on quality biomarkers (%). Linear regression was applied to determine if there was a linear relationship between Na2H2P2O7 and the CIE(Lab) system parameters: L*(D65), a*(D65), and b*(D65). The results showed significant effects of Na2H2P2O7 in fat content (%) and water (%), thus influencing the colorimetric profile.

Lately, there have been increasing efforts to stimulate the strategic role of the bees in biodiversity protection, in agriculture & horticulture. European Union (EU) has invested in the beekeeping sector in the last years by funding Farm to Fork strategy. The aim of this strategy is to protect them and preserve their contribution in sustainable environmental models. Biodiversity is decreasing by using intensive agriculture, chimization and automatization and consequently a decline in ecosystem services in many parts of the world, most representatives being pollination. Over the past three decades, there was an increasing in atmospheric temperature. Because of changes in plant flowering times patterns, the interaction between pollinators and their food sources is also affected. The challenges facing bee health have multiple sources, including poor nutrition due to less nectar source, heat stress resulting from global warming, agrochemicals used in agriculture, and pathogens becoming increasingly resistant to conventional treatments. However, thermal stress can negatively affect hive activity, which can affect foraging activity, immunocompetence, reproductive capacity, and the growth and development of bees. This, in turn, will affect pollination services and hive production overall.

Bakery products industry occupies a very important place in people's major consumer products. Bread is a staple product that almost all of us consume every day. These foods provide the human body with an important part of the nutrients it needs for vital activity. A first objective of this work was to obtain two innovative assortments of white bread enriched with different additions: one with the addition of turmeric (Curcuma longa) radix powder and linseeds (Linum usitatissimum) (B1) and the second with the addition of sea buckthorn (Hippophae rhamnoides) fruits powder, sunflower (Helianthus annuus) and white sesame (Sesamum indicum) seeds (B2). A second objective was analysing the two enriched breads in terms of total polyphenols content, antiradical and antioxidant activity compared to the control (B0 - plain white bread). Porosity, proximate composition, energy value of the breads as well as their sensory characteristics were also determined. Total polyphenol content in B2, respectively B1 breads was with 66% and respectively 49% higher than the control (1.41±0.02 mg gallic acid/g). Anti-radical activity of the products was improved by 2.3 times in B2 and with 43% in B1 compared to plain white bread (38.76±0.19%). The porosity of B0 bread was the highest (68%), decreasing for B1 (60%) and B2 (53%) assortments. In terms of proximate composition, the additions of natural seeds and powders resulted in increased lipid and dietary fiber content, compared to the control. At the sensory analysis, B1 and B2 were rated higher than the control, with B2 scoring best (between 4.70 and 4.85).

Dairy products represent food appreciated by a large number of consumers, of all ages. The aim of this work was to fortify yoghurt with bee products and to characterize sensory, physico-chemical and microbiologically the products obtained. We used for fortification: honey, pollen and royal jelly and propolis. Sensory evaluation showed good acceptability of all products, but the most appreciated were those with honey in combination. The addition of honey as such or in combination reduces the acidity of the fortified yoghurt. Antioxidant activity was greatly enhanced as a result of fortifying the yoghurt, with most antioxidants found in the royal jelly yoghurt sample. Antimicrobial activity was substantially inhibited by the presence of bee products.

The influence of weather conditions during the cold period of year on microclimate parameters of cowsheds and on the milk productivity of cows kept in traditional tethered conditions in typical brick cowsheds with natural ventilation was determined. It was established that in the conditions of Ukraine the temperature in cowsheds during the cold period of the year significantly depends on: the number of cows in them (r = 0.509; p = 0.018); the number of livestock per unit volume of the cowshed (r = 0.68; p = 0.001); the area of ventilation holes (r = 0.745; p<0.001). The humidity inside the cowsheds is most dependent on the outdoors air humidity (r = 0.514; p = 0.017), as well as on the number of cows per unit volume of the cowshed (r = 0.533; p = 0.013). In the cold period of the year the most problematic from the point of view of comfort for animals are periods of severe frosts. When cows were kept on a tether in typical brick cowsheds with natural ventilation and walking areas, the correlation coefficients between gross milk yield and: the average temperature outdoors were in the range of r = 0.625...0.636 (p<0.001); atmospheric pressure – r = –0.237...–0.276 (p≤0.001). A significant synchronicity of fluctuations in time of outdoor air temperature indicators and average milk yield per cow was established at periods of severe frosts: the decrease in daily milk yield due to frost reached 0.8 ... 2.2 kg per day (up to 21%). Cluster analysis established that for the synchronous distribution of days of the cold period into groups (clusters) based on the average outdoors night air temperature (tv) and gross milk yield (valmol), it is expedient to distribute the sample into 3 gradations.
