Changes in the gut microbiota of broiler chickens after Lactobacillus sp. probiotic treatments: a mini-review
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Târnoveanu, E.; Dumitru, Mihaela; Hăbeanu, Mihaela
Biotechnology studies have documented several positive effects of probiotic products on the animals’ state of health. Probiotic Lactobacillus sp. treatments applied to broiler chickens may help restore the balance of the gastrointestinal microbiota. The way probiotics act against pathogens can prevent microbial diseases and improve the host’s resistance to gut infections during physiological stress occurring in the intensive production system. Other advantages for the host expected from the use of probiotic products as feed additives are the synthesis of vitamins and the activation of the immune system. According to morphological approaches, there are some changes in the size of the intestinal absorption surface recorded after the administration of probiotic treatments to the broiler chickens. Such histological changes would relate to a better assimilation of the feed. Increasing the nutrient availability by the lactic acid bacteria colonies in the gastrointestinal tract improves the broiler chickens’ production. The probiotic treatments are associated with a reduction in the number of pathogen populations and an increased percentage of the beneficial microorganisms, both leading to a better health status of the host. The applicability of probiotic properties in vivo depends on keeping the appropriate ratio between the concentration of the probiotic products and the feed quantity adapted to the intense growth needs of the broiler chickens.

Emerging Technologies in Rural Development: A Scoping Review of Current Knowledge
(MDPI, 2026-05-15) Butnariu, Andreea; Ispas, Geta-Mirela; Fehér, Levente; Bejenaru, Alexandru-Emil; Coca, Oana; Ștefan, Gavril
Emerging technologies offer significant opportunities for sustainable rural development; however, their applications have not been systematically mapped across all dimensions of sustainability. This scoping review aims to identify, classify, and synthesize the literature on emerging technologies in rural development, structured around four pillars: economic, social, environmental, and governance. Eligible studies included English-language scientific articles published between 2015 and 2025 that propose solutions based on emerging technologies in rural contexts, identified in the Web of Science Core Collection database, following the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. Data extracted from the 129 eligible articles were synthesized in thematic tables and comparatively analyzed for each pillar. Results indicate an accelerated growth in publications after 2020, with machine learning, deep learning, and the Internet of Things dominating applications such as precision agriculture, telemedicine, and water management. Critical gaps persist in biodiversity monitoring, climate adaptation, elderly care services, and rural circular economy, with the governance pillar remaining the least represented. This study proposes an integrated framework and a knowledge map to guide future research and public policies toward balanced and sustainable rural transformation.

Role of probiotics in counteracting the effect of usual feed contaminants in swine
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Marin, Daniela; Pistol, Gina; Gras, M.; Rotar, C.; Taranu, Ionelia
The paper aims to investigate the potential of probiotics (a Lactobacillus polyculture-Lb) to counteract the effects of experimental co-contamination between E. coli, a common pathogenic bacterium in livestock farms responsible for post-weaning diarrhea in pigs and zearalenone, a Fusarium mycotoxin in order to achieve a nutritional strategy that reduces therapeutic interventions with antibiotics. For this purpose, growth performance, overall health status, immune response were assessed in 40 weaned piglets (10 piglets/group) distrusted in 4 groups: C- control, E1- E. coli+250ppb ZEA, E2- E. coli+250ppb ZEA+ Lb (product in development), E3- E. coli + 250ppb ZEA+ Lb (commercial product). Experimental groups received feed contaminated (E1, E2, E3) or not (C) with 250 ppb ZEA for the entire period of the trial (13 days). E coli was administered to E1, E2, E3 for 3 days at the beginning of the trial, followed by the administration of probiotic products for the rest of the period. Feeding piglets with co-contaminated feed had a tendency to decrease the body weight and feed consumption. No significant effect of the treatments was observed on the serum parameters. However, piglets from E2 group have a significant increase of IgA, IgM and IgG as compared with control, but no effect was observed on total antioxidant capacity or nitric oxide synthesis. In conclusion, the probiotic treatment can improve the immune status in piglets feed co-contaminated feed.

The influence of the slaughter age on the histological particularities on gray guinea fowl (Numida meleagris)
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Roşca, D.C.; Jitariuc Sava, Ştefania-Elida; Usturoi, Marius-Giorgi; Radu-Rusu, Răzvan-Mihail
Nowadays, more and more producers and processors around the world are concerned about ways in which they can make high quality food, in economic conditions. The aim of the research consists in studying elements related to the morphology and structural aspects of some muscles taken from the pectoral musculature of the guinea fowls males, traits that directly affect the trophic biological properties of the poultry meat. In Pectoralis major muscle cells for the samples issued from the birds slaughtered at 77 days thickness varied between 38.21 µm and 60.33 µm, resulting an average diameter of 48.55±0.40 µm. The values for the next group of samples (84 days), ranged from 40.03 µm to 62.39 µm resulting an average of 51.18±0.38 µm. The 3rd of samples (91 days-slaughter), provided us an average of 53.88±0.43 µm, based on a minimum value of 42.93 µm and a maximum value of 68.55 µm. The bundle cross section area of the 1st order muscle showed us values of 56343.48±1658.49 μm2 on the samples collected on day 77, followed by a bit higher value of 59597.76±1638.76 μm2 on the samples colleted on day 84; the highest value was recorded on day 91, more precisely, 62911.75±1790.08 μm2. The histological findings suggest that the meat of Pectoralis major muscles from guinea fowls slaughtered at the age of 77 days had a better texture, with thinner cells and less connective tissue, therefore a better sensorial quality.

Chitosan-Based Technologies in the Food Industry: Functional Properties, Advanced Applications, and Future Perspectives
(MDPI, 2026-06-18) Crivei, Ioana-Cristina; Rațu, Roxana-Nicoleta; Velescu, Ionuț-Dumitru; Lipșa, Florin-Daniel; Stoica, Florina; Balint, Andreea-Bianca; Pavel, Ina-Iuliana; Crivei, Luciana-Alexandra
Chitosan, produced through deacetylation of chitin from crustacean byproducts and, increasingly, fungal biomass and insects, is attracting food-sector interest because it combines antimicrobial activity, antioxidant capacity, biodegradability, and film-forming behavior in a single polymer. This review discusses how source, molecular weight (MW), degree of deacetylation, solubility, and charge density shape its performance in food systems. The paper then follows the main technological routes now tested or used: edible films and coatings, hydrogels, cryogels, nanoparticles, microcapsules, and hybrid matrices. These formats can protect fresh produce, meat, poultry, fish, seafood, and dairy foods, while also supporting beverage clarification, emulsion control, release of natural antimicrobials or antioxidants, and freshness monitoring in active or intelligent packaging. The evidence indicates strong promise, especially where microbial growth, lipid oxidation, moisture transfer, and short shelf life remain limiting factors. Yet, wider industrial use is still slowed by water sensitivity, sensory effects, raw-material variation, cost, process scale-up, and regulatory alignment. Future work should move beyond laboratory efficacy and address reproducible production, food-specific validation, and consumer acceptance.
