The objective of this study was to estimate the breeding values and genetic parameters for birth weight and weaning weight in Aberdeen Angus cattle breed with maternal animal model. Data consisted of records of 1206 calves of Aberdeen Angus breed from Aberdeen Angus Association Romania. The direct breeding values for birth weight were in the population between -12.8 and 21.93 and for weaning weight from -82.68 to 155.10. The direct breeding values for calves with records for birth weight were from -8.87 to 16.077 and for weaning weight from -71.51 to 150.26. The maternal breeding value for birth weight ranged between -2.772 and 3.388 and for weaning weight from -38.273 and 49.693 in the population. The maternal breeding values for calves with records for birth weight ranged between -2.206 and 1.668 and for weaning weight were from -25.824 and 27.906. The direct heritability for birth weight was 0.266 and for weaning weight was 0.217. The maternal heritability was 0.048 for birth weight and 0.081 for weaning weight. The total heritability was 0.24 for birth weight and 0.20 for weaning weight.

The purpose of the research was to carry out a real analysis of the degree of improvement for the traits that influence the quality of skins obtained from Karakul of Botosani lambs. The biological material was represented by lambs of both sexes obtained from adult sheep belonging to the respective breed. In order to evaluate the improvement of the modeling degree, assessments were made on several generations of lambs, starting with those from 2007 when the current Improvement Program is applied, those from 2015, 2020 and respectively from 2022. The working methods used are accepted by the experimental technique and the evaluation of the type of model was made based on the technical norms and in which it is specified that 50 points are awarded for very good modeling; for good modeling, only 25 are assigned, and for situations in which the modeling is satisfactory, only 10 points are given. Following the statistical processing of the data, it is found that the improvement process is more advanced in black variety lambs because an average score of 32.38 was obtained and from the total number of lambs evaluated in 2022, the proportion of those that were also associated with a valuable modeling was 66.8%.

Integrated professional swine farms produce enormous amounts of manure, wich has become a source of environmental pollution. Diversification of production systems, encouragement of alternative exploitation on free land, which contributes to changes in growth and exploitation, lower socio-economic and environmental impact, production with reduced consumption of resources without loss of nutrients and conservation of biodiversity through sustainable development of areas, can be solutions that can reduce pollution. The measures proposed for implementation, to reduce the environmental risk, refer to methods and techniques of statistical filtering and spatial grouping based on the density of swine, well-being, the level of accessibility of food and fodder resources, the level of accessibility of meadows for own pork production and the level of environmental pollution according to nitrogen (N) and phosphorus (P) excretion.

The purpose of this study was to analyze the health status of dairy cows from a farm in Moldova. A total of 30 feed samples were analyzed from a mycotoxicological point of view, and 90 blood samples were collected from cattle of the BNR breed, which were biochemically analyzed to investigate the state of health. Adverse effects of mycotoxins are manifested in health, production, and reproduction in ruminants, especially dairy cows, and in the population. During the experimental period, regarding mycotoxin contamination of feed, the levels of mycotoxins investigated (AFL-T, FUM, and DON) did not exceed legal limits. From a biochemical point of view, the parameters that did not fall within the limits of the reference interval and showed a slight increase were represented by ALT, Gamma GT, and urea. All cows involved in the study were apparently healthy at the time of sample collection, but the resulting biochemical analyses suggest possible mild liver disease (by increasing above the normal limits of the previously mentioned parameters).

Although fishmeal is an excellent feed component for trout, there are concerns about its sustainability. Overfishing and the environmental impact of fish meal production have raised questions about its long-term availability. Consequently, there's a growing interest in finding alternative protein sources for fish feed, such as plant-based proteins. The exploration of non-conventional ingredients in trout feed stems from a pressing need to safeguard the environment, promote aquaculture sustainability, and enhance consumer safety. By ensuring the safety of food products, consumer trust in purchasing aquaculture-derived fish is likely to increase, potentially reducing reliance on wild-caught fish. Within this framework, a comprehensive literature review was conducted to identify novel ingredient sources suitable for trout feed. This involved examining the origins of new plant-based ingredients, assessing their physical, chemical, and microbiological characteristics, and evaluating their impact on trout feed production. The findings of this study can inform and enhance feed management strategies in aquaculture, aligning with sustainability objectives and efforts to boost productivity.

Consumer’s dietary preferences are an ever-evolving mechanism subject to a series of dynamic factors, including their growing consciousness towards healthier food alternatives and sustainability. As industry’s focus tends to extend beyond conventional plant-based options, innovative results shed light on something deep beneath the surface, rooted in mycology. This study aims to investigate the intricate factors influencing the preferences and commercial behaviour of the Romanian consumer and how likely they are to accept and integrate Mycelium-based products into their current diet. The research involved collecting data through a questionnaire, which was subsequently completed by a target group, forming the representative sample. By interpreting the results obtained from data processing and statistical evaluation, we gained access to valuable insights regarding both the burgeoning field of alternative protein sources and how they link to the broader context of emerging trends in consumer behaviour.

Healthcare and life sciences represent a significant role in people’s lives, these two aspects governing their well-being and functioning. Redefining patient care methods and treatment solutions, working on thorough genomics studies and balancing healthcare costs have become an upfront priority for any healthcare and life science organization. A cloud infrastructure composed of applications, servers, networks, and data storage represents an effective solution to both business and technical goals, but also a modernization tool. For this study, we created a web-based program called HealthCloud, which facilitates medical data interoperability, provides automation services, and uses machine learning for predictions and insights related to the possibility of developing a cardiovascular disease, based on patient input regarding food and nutrition. Our results include a user-friendly interface, easy access to patient and doctor data, and a high accuracy of disease risk prediction with a machine learning model built in Amazon SageMaker. The proposed prototype proved its potential through the attained outcomes and presents an appropriate approach of healthcare management, which merges with cloud technology for the enhancement of care delivery.

The study presents the first data on the biodiversity of helminths and helminth communities of European perch (Perca fluviatilis Linnaeus, 1758) from the freshwater ecosystem of the anthropogenically affected protected area Mandra-Poda. Thirty specimens of perch were examined by the method of complete helminthological study. The infection characteristics and the dominant structure of the helminth communities were determined. Helminth communities were analyzed at two levels: infracommunities and component communities. Basic biotic indices are presented. The core species in the helminth communities of perch is Eustrongylides excises Jägerskiöld, 1909 larvae (Nematoda; Dioctophymatidae) (P% = 60; MI = 7.12; 1-51 specimens). New data on the content of heavy metals and their circulation in the system water-sediment-perch and its helminth Eustrongylides excisus have been established. New data on the bioindicator significance of helminths and helminth communities of European perch are discussed.

The paper presents data on the identification for the first time in Moldova of the helminth fauna structure of Rana dalmatina Bonaparte, 1840, and the determination of its role as bioindicators and as vectors for parasitic agents specific to animals. As result of helminthological investigations, 18 helminths species was established. The predominant group are trematodes with 61.1% of cases, nematodes with 27.7% of cases, acanthocephalan and monogeneans with 5.6% of cases each. According to the assessment of the main helminthological indices, it was established that the species is infested with helminths in 83.3% of cases. When evaluating the data and the composition of helminth species, it was found that adult forms of helminths are predominant over larval forms, so that, when the host species is infected with trematodes, 27.3% are metacercarias, and 72.7% are the adult forms, when the host species is infected with nematodes 20.0% are the larval stages, and 80.0% are the mature forms, when infesting the host species with acanthocephalans and monogeneans, it was established that the helminth species is an adult form, each constituting 5.6%.

In the autumn of 2022, an ecologohelinological study was carried out on 41 and 70 fish specimens, respectively, from the Luda Yana River and the Chepelarska River, falling into the Maritsa River basin in the territory of Bulgaria. The fish from the Luda Yana River were caught from three places (indicated as biotopes) - Popinitsi, Svoboda, and Chernogorovo, and belong to 3 species (Orpheus dace, Squalius orpheus Kottelat & Economidis, 2006; Round-scaled barbel, Barbus cyclolepis Heckel, 1837 and Bleak, Alburnus alburnus Linnaeus, 1758). The fish from the Chepelarska River were caught from one place - the Katunitsa biotope and belong to 4 species (Sq. orpheus, B. cyclolepis, Alb. alburnus, Vardar nase Chondrostoma vardarense Karaman, 1928). In both studied rivers, the dominant fish species caught is Sq. orpheus. The species diversity of the parasites and their ecological indicators are indicated for the non-dominant fish species. New habitats and new hosts have been discovered for some of the established helminth species.
