The paper presents a preliminary study on the effect of phenolic extract obtained from olive mill waste water (OMWW) in meat analogues based on vegetable proteins. For the first time, meat analogues enriched with phenolic extract, recovered from OMWW through filtration systems and spray-dry technology, were made. The antioxidant activity as well as the sensory properties of three different samples (control, ascorbic acid (0,5%) and phenolic extract (3%) from (OMWW), were evaluated. The results obtained are promising, opening up new opportunities for research on the exploitation of the use of olive powder in the production of foods rich in bioactive compounds, contributing to the sustainability of the environment and the circular economy.

In studies involving various bird species, DNA analysis is crucial due to the valuable data it can provide. Experiments on genetic diversity have become common in many areas of biodiversity science. Although obtaining high-quality DNA from samples is critical, surprisingly few reviews focus on effective field sampling techniques to preserve DNA before laboratory extraction. Research on wild bird populations often relies on DNA samples collected from easy sources such as blood, saliva, or cloacal swabs. DNA provides a wealth of information for researchers. Analyzing it can yield various insights, ranging from the identity of individuals (such as determining their sex and parental relationships) as well as gathering data on entire populations (like estimating population sizes and understanding the significance of gene flow between them). This paper aims to evaluate the specialized scientific articles and highlight the methods used to produce less stress on populations.

The objective of the research was to assess the impact of diet on the growth rate and carcass quality of Tsigai lambs, specifically the rusty variety, fed with different diets to enhance meat production and quality. A total of 24 male lambs (L1 and L2, n = 12 lambs per group) were subjected to a 100-day fattening trial following weaning. Notable differences (p<0.01) were observed between the two groups regarding final weight, total gain, and average daily gain. However, the diet did not have a significant effect (p>0.05) on carcass quality characteristics between the L1 and L2 groups (warm carcass yield, cold carcass yield and commercial yield), but had significantly influenced (p<0.001) the share of the main parts of carcasses (cutlet and shoulder + arm). The diet administered to the two lots of lambs influenced significantly (p<0.05) the share of bone and fat in carcasses, also, the carcasses from L1 were fatter, while the ones from L2 were more bony. No significant differences were recorded with regard at meat share in carcasses (p>0.05).

The scientific paper presents the experimental results of the use of a biologically active complex microbial preparation (CMP-3) for the growth of quail chicks. The experiment lasted 30 days and was carried out on two groups of Phoenix quails. During the period of 1-30 days the quails in the control group consumed combined feed, and those in the experimental group - combined feed with the addition of the 0.5% complex microbial preparation. The adding of the complex microbial preparation in the daily ration of quails ensured the viability of chicks of 100% compared to 91% in the control group, a significant increase in the body mass of chicks by 13.46% compared to the control, achieving economic efficiency of 0.23 €/head.

Demand for buffalo milk is on the rise, due to a shift in consumer choices towards healthier, more nutritious, and sustainable foods, this article aims to showcase the qualities of this product, particularly in terms of fatty acid (FA) composition. Romanian buffalo milk samples were collected from a buffalo farm in Mesendorf, Transylvania. The milk samples were individually collected at fixed intervals post-calving, across 3 milking sequences: beginning, middle and end of milking, from both primiparous and multiparous females, and analyzed in the laboratory. The study revealed that milking sequences significantly affected almost all FAs, and significant (P<0.05) interactions between days post-calving and milking sequences were observed for 6 out of the 14 fatty acids. Saturated fatty acids (SFA) averaged 74.29%, monounsaturated fatty acids (MUFA) averaged 23.43%, and polyunsaturated fatty acids (PUFA) had a mean of 2.28%. Milk Quality indices, like the Atherogenicity index (AI) or Thrombogenicity index (TI), among others, were calculated. Romanian buffalo milk of with an unsaturated to saturated fatty acid ratio of 0.35, shows a potentially healthy lipid profile.

In order to study the influence of pig sex and pre-slaughter weight on carcass quality, experimental studies were carried out on 120 pigs of Irish origin: 30 gilts with a pre-slaughter weight of 100 kg, 30 gilts with a pre-slaughter weight of 120 kg, 30 barrows with a pre-slaughter weight of 100 kg, 30 barrows with a pre-slaughter weight 120 kg. After fattening the pigs were slaughtered and their carcass qualities were evaluated. The analysis showed the influence of pre-slaughter weight on slaughter yield: in gilts by 1.7%, in barrows – no effect; on chilling losses: in gilts by 44.00%, in barrows by 26.32%; on fat thickness above the 6-7 thoracic vertebrae: in gilts by 21.19%, in barrows by 24.76%; on fat thickness in buttocks: in gilts by 22.65 %, in barrows – no effect; on fat thickness in withers: in gilts by 13.47%, in barrows by 14.9%; on carcass length: in gilts by 8.28%, in barrows by 4.62% and on the Loin eye area MLT: in gilts by 6.0%, in barrows by 13.50%.

The success of the fish eggs incubation period is conditioned by the quality of the biological material, the environmental conditions and, last but not least, the device in which the incubation is carried out. At Research and Development Station for Fisheries Nucet (S.C.D.P. Nucet), the incubation of eggs obtained through artificial reproduction of the silver carp Hypophthalmichthys molitrix (Valenciennes, 1844) is carried out in the "Carafa" type incubator. It had some disadvantages, which is why certain improvements were made. After their implementation, an increase in efficiency was observed, such as: reduction of labour, improvement of work quality, obtaining higher indices at the hatching percentage of 92.6%, the survival percentage from hatched larvae to 3-5-day old larvae of 91.3%, as well as the survival percentage from embryonated eggs to 3-5-day old larvae of 84.5%. Thanks to the innovative modifications made to the "Carafa" type incubator, they were implemented and are currently used successfully in the artificial reproduction station within the S.C.D.P. Nucet.

Livestock farming is a vital component of global food production, supplying essential resources such as meat and dairy. However, it is also a major contributor to environmental challenges, particularly greenhouse gas (GHG) and atmospheric pollutant emissions. The beef cattle sector is responsible for significant methane (CH₄) and nitrous oxide (N₂O) emissions due to enteric fermentation and manure management. Additionally, inefficient resource utilization and suboptimal farm practices exacerbate environmental degradation and economic losses. As global demand for livestock products grows, there is an urgent need to adopt sustainable farming practices that optimize production while minimizing ecological impact. We propose an innovative approach to sustainable livestock farming by integrating Internet of Things (IoT), blockchain, and artificial intelligence (AI) technologies. IoT sensors will monitor critical environmental and livestock parameters, The collected data is securely stored and managed using blockchain technology, ensuring transparency, traceability, and stakeholder trust. AI-driven models analyse input data to optimize feeding practices, manure management, and overall farm productivity. These technologies will form the backbone of a decision-support system designed to enable farmers to reduce emissions while improving operational efficiency.

Wildlife trade is strictly regulated by a range of international conventions and European regulations. As a member state, Bulgaria acts as an entering point to the EU. The current study investigated the intensity of trade with wild fauna based on official data on consignments admitted to the European economic area through Bulgarian border control posts. For the period from 2020 to 2024, we identified the animals by species and categorised them into groups based on their protection status. All consignments with live animals were traced from the country of origin to their final destination within the EU. Emphasis was made on the mandatory requirements when the wildlife trade is concerned with protected species.

Romanian marine aquaculture is a recent development, as a consequence of both harsh environmental conditions and a cumbersome legislative framework. The much-awaited settlement of the water concession opened the way for this activity. After the successful testing of rainbow trout Oncorhynchus mykiss (Walbaum, 1792) and gilthead seabream Sparus aurata (Linnaeus, 1758), this research aimed at investigating the potential of European seabass Dicentrarchus labrax (Linnaeus, 1758) for culture under Black Sea conditions. The laboratory experiment demonstrated the possibility of transferring 4-months old juveniles from a salinity of 35‰ directly into brackish water (salinity 15‰), with no mortalities and rapid post-stress recovery (24 hours after transfer glycaemia levels returned to normal, with a mean value of 78 mg·dL-1). A control batch was kept at the original 35‰ salinity. Biomass increase was normal, from 7-8 grams initially to 300 g after nine months (during autumn-winter), with no significant differences between salinities. The species proved its suitability for culture at the Romanian coast especially due to its wide temperature range tolerance, being able to feed and grow during colder Black Sea winters.
