The aim of this research trial was to assess the nutritional and health status during the transition period of dairy cows. The transition period is characterized by increased energy requirements and a reduction in the intake of dry matter of the lactating cows. The study was carried out at the Experimental Farm of the Research and Development Institute for Bovine Balotesti, Romania. Blood samples were collected from a number of 50 purebred Romanian Black and Spotted dairy cows during the last 3 pre-partum and first 3 post-partum weeks (3 weeks pre-partum, 1 week pre-partum, at calving, 1 week post-partum and 3 weeks post-partum). A total of 250 blood samples were analysed for serum proteins (total proteins, albumin, urea) and mineral indicators (total calcium, phosphorus and magnesium). During the transition period, the obtained serum values for protein profile were not significantly (P>0.05). The concentration of calcium and phosphorus of blood did not show differences (P>0.05) between sampling period, except the level of magnesium (P<0.05) after partum period comparative with pre-partum period. Current results revealed the importance of the serum indicators as a potential tool for monitoring the nutritional status of the dairy cows at farm levels.

Agricultural production plays an integral role in the regional economy, under the conditions of climate change with uneven distribution of rainfall and extreme heat, expansion of areas with degraded soils, affecting agricultural productivity. The identification of alternative crops that need less water and produce increased yield of organic matter per unit of water is important for agricultural sustainability. Adequate animal nutrition is one of the vital prerequisites to enhance the productivity and the performance of ruminants in terms of milk and meat production. Silage is one of the key components of the feed for herbivorous domestic animals. Sorghum species have recently gained popularity due to their numerous advantages, such as heat and drought tolerance and resistance to specific diseases and pests. Besides, they are well adapted to a wide range of soil types and recover easily after grazing or multiple harvests. The aim of this study was to determine the green mass yield, the silage quality, the nutrient content and the fodder value of the nonnative, perennial, rhizomatous grass – Sorghum almum, grown in an experimental field of the National Botanical Garden (Institute), Chişinău. In the third growing season, the perennial sorghum was characterized by high growth rate and regenerative capacity after being cut. The annual productivity, from three harvests, was 6.1 kg/m2 green mass or 1.4 kg/m2 dry matter, surpassing the productivity of maize by 35 %. It was determined that the quality of the silage varied depending on the harvest time: pH 3.8-4.5, lactic acid 24.7-45.5 g/kg, acetic acid 6.3-9.1 g/kg, butyric acid 0.2g/kg, organic matter 892.4-922.8 g/kg, crude protein 50.7-95.2 g/kg, crude fats 20.6-36.8 g/kg, crude cellulose 402- 428.9 g/kg, nitrogen free extract 330.5-407.2 g/kg, carotene 15.67-47.17 mg/kg, calcium 3.7-5.5 g/kg and phosphorus 1.8-2.7 g/kg. The fodder value of the prepared silage was 0.14-0.18 nutritive units/kg and 1.47-1.82 MJ/kg metabolizable energy. The potential methane yield of Sorghum almum silage substrates varied from 233 to 242 l/kg. The silage obtained from Sorghum almum, according to organoleptic characteristics (smell, colour and consistency) and biochemical indices (pH, content of organic acids and their correlation, chemical composition), largely meets the standards and can be used as alternative feedstuff.

The experiment aimed to determine the impact of environmental light (spectrum, intensity, and photoperiodicity) on the growth performance of juvenile catfish (Silurus glanis, L., 1758), reared in a recirculating industrial aquaculture system (RAS). The experiment was conducted over 60 days and was organized two variants of light intensity, were compared, in replicate, as follows: in first variant (V1) we used green light with an intensity of 80 lx and in the second version (V2) white light with an intensity of 260 lx. The same photoperiodicity regime was applied in both variants 12L:12D. The initial stocking density was 15.66 kg m-3. The indicators of growth performance, obtained at the end of the experimental period, registered the following results: in the experimental variant V1 (white light), the final stocking density was 28.75 kg m-3, SGR 1.44 %/day compared to V2 experimental variant (light green), compared to a final stocking density of 29.99 kg m-3, a value of 1.31% day-1 for SGR were recorded. The final results of the study indicate a higher growth performance for the experimental variant with a green light (V2), a fact which demonstrates that juvenile catfish show technological plasticity concerning light regime.

Recent literature provides studies of the benefits of Nigella sativa cold pressed seed oil (NSSO) cheese enrichment, but insufficient data is available on the effect on the physico-chemical cheese properties. Three batches of traditionally manufactured raw milk brined cheese were considered: control cheese without NSSO and cheese samples enriched with 0.1 and 0.2 w/w NSSO. Experimental cheese samples were analyzed in duplicates for moisture contents, at 0, 14, 28, and 42 days of ripening, according to the AOAC Official Method 926.08. Data indicates moisture loss during ripening, which is consistent with most literature findings, and strong statistical significance could be associated to the trends of moisture decrease (f-ratio value - 59.07682; p-value - 0.00001), results being consistent with other sources which communicated p values <0.05 for moisture decrease findings. However, the slightly higher moisture values for the NSSO added cheeses were positively associated (p-value - 0.05). The data indicates slightly better moisture retention for 0.2% w/w NSSO cheese batch, which might be linked to a possible prevention of loss of body and texture loss during ripening of soft brined cheese.

Cheese creamis a category of dairy product highly appreciated by people of all ages, due both to its sensory characteristics and very pleasant texture, as well as its nutritional properties.Also, the lingonberries, both fresh and candied are considered very valuable because of their antioxidant and nutritional properties. The aim of this studyis to assess the impact of addition of candied lingonberries, in different proportions (10%, 15%, 20%, 25%),on the physicalchemical, microbiological characteristics and antioxidant properties of cheese cream. The experimental results of this research showed a decrease in themoister content and titratable acidity of the cream cheeseswith increasing of the proportion of fruit addeddue to the replacement of fresh cream cheese with candied fruit, whose acidity is lower. Further the total soluble solids content of the samples increased with the amount of added fruit. The total antioxidant activity and total polyphenol content of the cheese cream have been significantly improvedby using the candied lingonberries in the cheese cream formula.In the same time, was found that the microbial load of cheese creams with candied lingonberries decreased with increasing the amount of fruit added.Thus, the addition of candied lingonberries in the cream cheese formula resulted in a change of all the analyzed parameters and could be recommended as natural antioxidants in this type of dairy product.

The use of additives in the meat industry must ensure that obtained products are appreciated by consumers, provided good yields are achieved. Thus, the work follows the influence of water, salt, polyphosphate and fat additions, on heat treatment losses, hardness, as well as sensory properties of meat products. Analyzing the experimental results it has been found that with the increase in the percentage of water and fat added, cooking losses increased, while the hardness decreased. Increasing the addition of salt has determined to a decrease in heat treatment losses and increased hardness of thermally treated products. The addition of polyphosphates increasing has generated to a decrease in heat treatment losses and hardness of products. By following the degree of sensory satisfaction, in general, increasing the addition of water, salt, polyphosphates has led to appreciated products, with the exception of the increase in added fat that has led to a decrease in the satisfaction of consumers.

Monitoring fish fauna in altered aquatic habitats may provide relevant information regarding the distribution, presence or absence, and dynamics of fish species. Someșul Cald River is the main tributary of Beliș-Fântânele Reservoir and Dam, build from 1970 to 1974. The presence of the dam could have affected fish fauna, especially potamodromous brown trout Salmo trutta and European grayling Thymallus thymallus because of habitat obstruction. Altitude, riverbed width, water depth, and water velocity are easy to determine aquatic environmental parameters. River altitude and riverbed width played an important role in European grayling preference regarding the auspicious environment. Correlation coefficients showed that increasing altitude is a limiting factor for European grayling (r=-6024*, p<0.05). Wider riverbed is preferred by the same species (r=0.672*, p<0.05). Beliș-Fântânele Dam blocked the migration of fish and made the grayling ecological zone framed by two trout ecological zone (upstream and downstream). The distribution range on the altitude of the brown trout in Someșul Cald River was from 518.5m to 1153.5m and 577.5m to 1068.5m for the European grayling.
