Improving economic efficiency on degraded permanent meadows by various management system
(University of Agricultural Sciences and Veterinary Medicine, Bucharest , Romania, 2024) Acatrinei (Dumitriu), Simona; Stavarache, Mihai; Gavrilă, Cristian-Sorin; Vacarciuc, Elena-Manuela; Dudău, Ana-Maria; Bouruc, Daniela; Stavarache, Elena; Paraschivu, Mirela; Sălceanu, Călin; Brezuleanu, Stejărel
The purpose of this research is to study the possibility of enhancing the multifunctionality of permanent degraded grasslands by overseeding, with special look on economic efficiency. The experience that is the subject of the research was organized in the Research and Development Station for Meadows, Vaslui area, on a Dichanthium ischaemum (L.) Roberty meadow. In the study area there are large areas of permanent meadows, at different stages of degradation, due to the positioning on surfaces with different degrees of inclination, eroded or subject to erosion process, due to abandonment or non-rational use, with an inappropriate load of animals and failure to apply maintenance or improvement measures. Due to these aspects, the production is small and the floral composition is dominated by species with medium and low fodder value. In order to increase the production of permanent grassland in the area, it was considered necessary to apply organic fertilizers, and their effect was compared to that of abandonment, mulching or simple use, and with overseeding measures. Biological material used (a mixture of: 70% Bromus inermis Leyss. + 30% Onobrychis viciifolia Scop. - 30 kg·ha-1 + 25 kg·ha-1). Total expenses, net income and profitability rate (rate of return) were calculated. The lowest costs were recorded when the biomass was only harvested, no other action being performed. When overseeding and fertilization were overlapping the costs were the highest, the economic efficiency being carried close to zero, but more likely, the effect of fertilization has been greatly diminished due to poor climatic conditions.

Phenotypic variation, body conformation, and relationships between biometric traits and live weight in young sheep from three genetic combinations
(“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2026) Pascal, Constantin; Bulmagă, D.; Ciobanu, I.; Neagu, D.
The study evaluated phenotypic variation and body conformation in young sheep obtained by crossing Tigaie ewes with rams of French meat breeds, namely Berrichon du Cher (BC×TI), Blanche du Massif Central (BMC×TI), and Vandeen (V×TI). To characterize body development, trunk length, withers height, rump height, chest circumference, cannon circumference, trunk depth, and live weight were measured. Descriptive statistics, factorial ANOVA with the effects of genetic group, sex, and genetic group × sex interaction, Pearson correlations, conformation indices, principal component analysis, and multiple regression were used. Differences among genetic combinations were detected for withers height, cannon circumference, trunk depth, and live weight. Live weight showed the strongest correlations with trunk length (r=0.826; p<0.001) and trunk depth (r=0.763; p<0.001). The multiple regression model based on trunk length, chest circumference, and trunk depth explained 75.65% of the variation in live weight (R²=0.7565). The results describe phenotypic differentiation at the age of evaluation and were not used to estimate heterosis because the available values for the parental breeds were obtained from adult animals.

Cadmium contamination in cow's milk: sources, occurrence and implications for food safety
(“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2026) Matei, Mădălina; Petrescu, Silvia-Ioana; Mădescu, Bianca-Maria; Lăpușneanu, Dragoş-Mihai; Simeanu, Daniel; Pop, Mircea-Ioan
Cadmium is a toxic heavy metal with a high bioaccumulation capacity, the presence of which in milk raises food safety and public health concerns. The aim of this article is to analyze the existing data from the specialized literature regarding the sources of cadmium contamination, the transfer mechanisms in the bovine body and the levels detected in milk. A literature review was conducted using studies published in different geographical regions. Data sources included survey articles, field analyses and systematic reviews focused on heavy metal pollution. The available studies report a significant variability in the level of contamination influenced by exposure routes, region, growing environment and diet, some values approaching or even exceeding the legal limits allowed at European and international level. The highest cadmium concentrations were reported in areas with heavy traffic or industrial activity, with most studies confirming the wide variation in contamination and its correlation with the degree of urbanization and industrialization. The cadmium contamination of milk reflects the direct influence of anthropogenic factors and environmental pollution on animal production.

Determination of sodium nitrite (E250) content in some selected meat products
(“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2026) Radu Rusu, Cristina-Gabriela; Pop, Mircea-Ioan; Petrescu, Silvia-Ioana; Lăpușneanu, Dragoş-Mihai; Matei, Mădălina; Albu, A.
The main objective of this study was to evaluate the nitrite content in different meat products using the colorimetric Griess method, according to the Romanian Standard SR 13175. Six samples from different brands were analyzed, grouped into two categories: canned pork meat in its own juice and Victoria-type salami. The results revealed important differences between the two product categories. The canned pork samples showed lower nitrite concentrations, all below the maximum limit of 50 mg/kg established by national regulations. Conversely, Victoria-type salami samples presented higher nitrite levels, approaching the legal threshold of 100 mg/kg, as regulated by EC Regulation No. 1333/2008. These variations are mainly attributed to technological differences in processing, the controlled addition of curing agents, and the type of thermal treatment applied. In conclusion, all analyzed samples complied with the legal safety limits; however, salami products exhibited higher nitrite concentrations than canned meat, emphasizing the importance of continuous monitoring of food additives to ensure consumer safety and regulatory compliance.

Microplastics and nanoplastics in the food chain of farm animals: impacts on health and productivity
(“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2026) Poroșnicu, I.; Borș, S.-I.; Ariton, A.-M.; Davidescu, Mădălina-Alexandra; Mădescu, Bianca-Maria; Vintilă, V.; Ailincăi, Luminița-Iuliana; Mareș, Mihai
Pollution from microplastics (MP) and nanoplastics (NP) has emerged as a central concern in environmental and health research. While most studies focus on aquatic ecosystems, recent evidence highlights direct contamination of livestock farms through feed, water, soil, and equipment. Ingested particles disrupt the gut microbiome, inducing dysbiosis, local and systemic inflammation, and reduced digestive efficiency. Chronic exposure is associated with metabolic disorders, oxidative stress, and liver dysfunction, with consequences for growth, reproduction, and overall productivity. Detection of plastics in milk, meat, and eggs suggests direct transfer to consumers, raising significant food safety and public health concerns. Within the One Health framework, these findings emphasize the interdependence of animal, human, and environmental health, underlining the urgent need for monitoring, risk mitigation, and integrated management strategies. This paper provides an integrated review of exposure sources, physiological effects, and broader health implications of MNP in animal production.
