Aspects regarding the operating pressure inside the milking teatcup liner
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Chirilă, Constantin; Roşca, R.
stract The paper presents some preliminary results regarding the pressure variations inside the teatcup liner, during the milking process. The analysis was performed on the upper part of the liner, which has contact with the teat during milking. A proprietary test rig was used for the experiments; the system was equipped with a proprietary electro-magnetic pulsator, which can provide two milking ratios (1:1 and 3:1, respectively). Milk flow through the teatcup was simulated using water stored in an open tank of the test rig; water was chosen because its density is close to milk density. The tests results are presented within tables, for the two milking ratios used during the experiments. The tests showed that only small pressure variations were recorded in the liner-teat contact area. The small differences among the average values suggest that pressure inside the liner may be considered to be constant during milking.

Effects of Grafting and Fertilization Treatments on the Functional and Nutritional Quality of Eggplant Cultivars
(MDPI, 2026-08-14) Elhawary, Saad Masooud Abdelnaby; Ciubotărița, Anamaria; Ordóñez-Díaz, Jose Luis; Moreno-Rojas, Jose Manuel; Teliban, Gabriel-Ciprian; Nicola, Silvana; Roșca, Mihaela; Stoleru, Vasile
The nutritional and functional quality of eggplants is heavily influenced by biological and technological factors. This study evaluated the effects of cultivar, rootstock, and fertilizers on the nutritional and functional quality of eggplant (Solanum melongena L.). Two commercial hybrids (Mirval and Black Pearl) were assessed with respect to two rootstocks (Solanum sylvatica and Rezistar F1) and three fertilization regimes: biological (Micoseed®), organic (Orgevit®), and chemical (Nutrispore®). These were compared with ungrafted and unfertilized cultivars. Fruit samples were analyzed for total polyphenol content (TPC), antioxidant capacity (ABTS and DPPH assays), chlorophyll a and b, lycopene, and tannin concentrations. Mirval exhibited significantly higher levels of TPC, antioxidant activity, photosynthetic pigments, and lycopene than Black Pearl. Ungrafted plants and those grafted onto S. sylvatica showed superior fruit quality, particularly when combined with organic or chemical fertilization. The highest concentrations of polyphenols (3.61 mg·100 g−1 DW), lycopene (3.18 mg·100 g−1 DW), and total chlorophylls were recorded for Mirval fruits from ungrafted or S. sylvatica-grafted plants under organic or chemical fertilization. These findings indicate that optimizing cultivar–rootstock combinations and fertilization management can significantly enhance the functional quality of eggplant fruits. The findings also support the use of organic fertilization as a sustainable strategy in protected vegetable production systems.

Health Challenges in Semi-Open Mountain Reservoir Aquaculture: A Case Study in Oncorhynchus mykis
(MDPI, 2026-07-30) Rîmbu, Cristina-Mihaela; Horhogea, Cristina-Elena; Carp-Cărare, Cătălin; Grecu, Mariana; Aniță, Adriana-Elena; Aniță, Dragoș-Constantin; Barbacariu, Cristian-Alin; Burducea, Marian; Motrescu, Iuliana; Popovici, Ivona
Bacterial diseases remain a significant threat to salmonid aquaculture worldwide, especially in semi-open cage culture systems that are exposed daily to natural aquatic environments. This study investigates recurring bacterial disease events in Rainbow Trout (Oncorhynchus mykiss) raised in a semi-open cage culture facility in the Bicaz mountain reservoir in Romania. Longitudinal monitoring was conducted through clinical assessment of fish health, post-mortem examination of fish that died during recurrent mortality events, bacterial isolation followed by MALDI-TOF MS identification, and determination of antimicrobial susceptibility profiles of the isolated bacteria from 2023 to 2026. These investigations demonstrated the presence of classical pathogenic bacteria found in salmonids as well as a diverse range of opportunistic environmental bacteria. Recurrently identified bacteria included Aeromonas hydrophila, Yersinia ruckeri, Aeromonas salmonicida, Aeromonas veronii, Pseudomonas fluorescens, Hafnia alvei, Enterobacter aerogenes, Providencia alcalifaciens, and Flavobacterium psychrophilum. Mixed bacterial infection resulted in several of the bacterial disease outbreaks, indicating that there are likely to be complex microbial relationships within this semi-open aquaculture environment. Susceptibility profiles of antibiotics tested against the isolated bacteria indicated that some antibiotic classes had varying degrees of susceptibility between different bacterial disease outbreaks and also varied between susceptible and resistant strains of the same bacterial species. Susceptibility profiles were most commonly noted for florfenicol and fluoroquinolone, while beta-lactams, macrolides, and lincosamides displayed variable levels of resistance or diminished susceptibility patterns, particularly among Aeromonas spp. strains. Therefore, the results highlight the dynamic epidemiological characteristics of bacterial infections occurring in semi-open mountain aquaculture systems and underscores the importance of longitudinal bacteriological surveillance under commercial farming conditions. Permanent interaction between cultured fish and the aquatic microbiota may influence the recurrence and microbial complexity of bacterial outbreaks in reservoir-based salmonid aquaculture.

Study of the body weight and biometric measurements in crossbreed newborn calves
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Enculescu, Marinela; Nicolae, Ioana; Sertu, St.; Vidmichi, Daniela
stract The aim of this study was to evaluate the body weight and biometric measurements on crossbreed newborn calves comparative with Romanian Black Spotted newborn calves. Our researches was carried out in the Dairy cows' Farm of I.C.D.C.B. Balotesti. We have taken into consideration four experimental groups (E1 Romanian Black Spotted x Charolaise, E2 Romanian Black Spotted x Blanc Blue Belgique, E3 Romanian Black Spotted x Aberdeen Angus, E4 Romanian Black Spotted x Limousine) and one control group (M) Romanian Black Spotted, with n=5 heads/group. The main body measurements performed were: body length (BL), height at withers (HW), height at rump (HR), height at chest (HC), perimeter of the thorax (PT), perimeter of the shin (PS), length of rump (LR). Means± (standard error), standard deviations (sd) and coefficients of variation (V) of body weight and biometric measurements were calculated. To obtain the significance of the differences, the Student’s test was applied. The mean values obtained for the body weight was distinct statistically significant (p<0.01) in the case of group E1 and statistically significant (p<0.05) in the case of group E2 comparative with the control group M. The average values recorded for height of chest (HC) was 34.20±0.37 cm in E2 comparative with 31.80±0.49 cm in M group (p<0.01). The mean value for perimeter of the shin varied between groups, for E2 and E3 groups values were close to the native race (BNR), but very statistically significant differences between group E4 and control group M (p<0.001). The analyzed quantitative traits showed some better performances for crossbreed calves comparative with BNR calves.

Effect of the dietary oregano (Origanum vulgare L.) powder and oil on the performance, carcass and organs development of broilers reared under heat stress (32°C)
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Vlaicu, P.Al.; Panaite, Tatiana-Dumitra; Olteanu, Margareta; Turcu, Raluca-Paula; Saracila, Mihaela; Criste, Rodica-Diana
An experiment on COBB 500 broiler chicks, reared under heat stress, evaluated the effect of the oregano (Origanum vulgare L.) powder and oil, on broiler performance, carcass and organ development. The study used 80, 1 day-old Cobb 500 chicks, weighed individually and housed in an experimental hall with 32°C constant temperature, humidity 36% and 23 h light regimen. During the starter stage (1-14 days), all chicks received a conventional diet formulation with corn and soybean meal as basic ingredients. During the growth stage (14-42 days), when the actual feeding trial started, the chicks were weighed, assigned to four groups (C, C1, E1, E2). Compared to the conventional diet C (with monensin in the premix for the grower phase), diet formulation C1 didn’t include monensin in the premix. The diet formulations for the experimental groups were similar with formulation C1 but differed from it by the addition of 0.01% oregano oil (E1), or 0.005% oregano oil plus 1% oregano powder (E2). The chicks had free access to the water and feed. Throughout the experimental period from 14 to 42 days, body weight gain was recorded weekly and feed intake was recorded daily. At the end of the feeding trial, 5 chicks from each group were slaughtered in order to make measurements of the relative weight of carcass cuts and internal organs of broilers.
