In this paper were analyzed the scientific bibliographic sources regarding the physiological and biochemical role of zinc on the tissues and organs of the organism of breeding roosters. In addition, in laboratory conditions, our researchers studied hematological, biochemical indices as well as glycine, glutamate and cysteine content in blood serum, seminal plasma and reproductive cells of breeding roosters. It is established that this element has a beneficial action on the organism of breeding roosters, maintaining and stabilizing the indices listed above at the level of physiological norms, compared to the roosters from the control group, and at the same time participating in the antioxidant protection of cells and maintaining cell homeostasis by balancing transmembrane metabolism.

The main objective of this research was to evaluate the quality of green mass, hay and silage prepared from perennial ryegrass Lolium perenne and tall fescue Festuca arundinacea, grown in monoculture in the experimental plot of the “Alexandru Ciubotaru” National Botanical Garden (Institute), Chisinau, Republic of Moldova. It was established that the concentration of nutrients and energy in whole-plant dry matter of studied grass species, harvested in pre-flowering stage was 10.74-14.10% CP, 3.10-3.58 % EE, 29.95-31.66% CF, 36.35-45.76% NFE, 6.20-19.24 % sugar, 1.54-2.99 % starch, 10.45-14.31% ash, 2.9 g/kg Ca, 2.5-2.7 g/kg P, 8.93-9.49 MJ/kg ME and 4.97-5.06 MJ/kg NEl. The biochemical composition of the prepared silages was: pH= 4.06-4.21, 27.9-28.9 g/kg lactic acid, 0-0.4 g/kg butyric acid, 1.5-5.0 g/kg acetic acid, 9.12-9.67% CP, 3.37-3.99% EE, 39.16-41.30% CF, 30.53-37.37% NFE, 0.33-1.40 % sugar, 0.50-0.60 % starch, 10.98-14.51% ash, 36.34-56.33 mg/kg carotene, 8.31-9.53MJ/kg ME and 4.48-5.34 MJ/kg NEl. The nutritive value of prepared hay: 9.95-10.84% CP, 1.87-2.55 % EE, 36.90-37.32% CF, 38.48-39.99% NFE, 10.82-11.28% ash, 2.5-3.5 g/kg Ca, 2.6-2.7 g/kg P, 8.31-8.85MJ/kg ME and 4.54-493 MJ/kg NEl. The studied grass species contain a lot of nutrients, which make them suitable to be used as multi-purpose feed for livestock.

At present, the known populations of Lycaena helle from Romania are found at a lower altitude than those from Western and Central Europe. Besides land-use changes, climate warming severely threatens this specie that prefer humid and cool habitats. Withdrawal to higher altitudes is also restricted by the species’ low dispersal ability. Therefore, the future of the Romanian population is uncertain. While implementing a peatlands restoration project in the northeastern part of the country, we investigated the local invertebrate fauna around a bog woodland from Dornelor Depression (Suceava County). Here we found a mosaic of wet habitats sheltering a violet copper population. This population was mentioned long ago, representing the first recorded instance of this species in present-day Romania. The violet copper butterfly has not been spotted in the area since the initial record was published in 1897, and current literature only refers to it as historical data from the Dorna Depression. We describe the habitat occupied by this population, bring up to date the specie’s distribution, and prompt for the designation of a special area of conservation for this European protected species.

The climate changes of recent years require more and more the finding of alternative solutions for the provision of electricity at the farm level. More farmers from countries such as Germany, France, Italy or USA use agri/agrovoltaic systems. Such a system used in livestock farms and placed directly on the grassland, allows, in addition to obtaining the necessary electricity for the operation of essential consumers (e.g. watering system, electric fence or electric tractor), providing shaded spaces for species such as sheep, cows or rabbit. Research carried out over the years has demonstrated the effectiveness of such systems, especially in the case of shade-tolerant fodder crops (clover, alfalfa). At the EU level, legislative solutions are being wanted that can be easily implemented in the member states and that can support farmers. This study reviews and analyzes the existing legislative solutions for Romanian farmers and opportunity to use agrivoltaic systems on the lands intended for grazing and the cultivation of fodder plants.

In this study, the nutritional, physicochemical, phytochemical and sensory potential of Moringa flour, composite Moringa/wheat flours in different proportions, and bread obtained from these flours were examined. The nutritional analysis revealed an increase in the mineral content of the bread with the addition of 10% Moringa flour, as well as an increase in protein and fat content. The results obtained show that the maximum mineral and fat contents were recorded in the case of bread with 10% Moringa flour and are 3.89% and 4.93%, respectively. They also show that the addition of moringa flour results in an abundance of micro- and macro-nutrients in composite flour samples and breads depending on the percentage added. The bread containing 2.5% of Moringa flour has values close to the control bread in terms of physical properties: 83.88%, 250.57 cm3/100 g, 93.66% and 0.717 respectively for porosity, volume, elasticity and H/D ratio. The total polyphenol content was between 191.87 and 279.83 mg/100 g and flavonoids between 6.18 and 9.76 mg EQ/100 g. The sensory analysis showed a reluctance of consumers to bread with more than 2.5% of moringa flour. This study reveals that the addition of moringa leaf flour up to 2.5% allows obtaining an elastic bread, acceptable from an organoleptic point of view while improving the nutritional quality without negative effects on the physicochemical characteristics.

The aim of this paper is the assessment of thermal stress effects on dietary fats. For this purpose, oils and fats from those sold on the Romanian market, intended for home use and in public food establishments were selected (sunflower oil, palm oil, lard and vegetable fat). These oils and fats are some of the most used ones in cooking. Dietary fats were subjected to heat stress by gradually heating to different temperature levels as well as repeated exposure to high temperatures. Subsequently, the influence of temperature on the characteristic parameters of food fats was analysed: free acidity, indices of: acidity, iodine, peroxide, saponification, refraction, water content and volatile substances, unsaponifiable matter. The results of the present study provide useful information for choosing a dietary fat suitable for frying food, in order to minimize the undesirable effects for the health of the consumer and to obtain a quality fried product.

Carmoisine is a food coloring found in many foods, with several restrictions. The aim of this work was to evaluate the hematological and biochemical parameters of blood in Wistar albino laboratory rats after oral administration of carmoisine every day for 6 weeks by dissolving the additive in water. The effect of temperature on parsley was also studied, drying it at different temperatures, then observing at what temperature the amount of ascorbic acid was maintained in the greatest proportion. At most haematological parameters, higher values were observed in rats in the 100 mg carmoisine group compared to the control and parsley groups. Similarly, the biochemical parameters analyzed showed higher values in rats in the group receiving 100 mg carmoisine compared to the control group, and parsley administered to rats was able to bring mean values closer to those obtained in the control group.
