In the mares of purebred Arabian horse (n-8) and East Bulgarian horse (n-12) breeds, raised in the State stud farm 'Kabiuk' near Shumen, Bulgaria, were studied basic hematological and biochemical blood parameters in the beginning of spring (March). It was established that the average levels for the mares from both breeds are as follows: alanine aminotransferase ALT U/L - 73.00±14.47, lactate dehydrogenase LDH U/L - 1523.88±93.11, creatinine Creat. U/L - 284.56±53.08, calcium Ca U/L - 2.06±0.4, total bilirubin TBL U/L - 78.40±12.45, phosphorus P U/L - 6.63±0.51, white blood cells WBC - 8.87±0.71, lymphocyte count Lym - 32.94±2.48, monocytes Mon-3.98±0.30, granulocytes Gra - 61.45±2.74, red blood cells RBC - 8.01±0.14, erythrocyte volume MCV - 67.07±28.42, hematocrit Hct - 35.12±1.54, hemoglobin MCH - 12.34±0.16, erythrocyte distribution width RDW-16.90±1.42, hemoglobin Hb-11.16±0.67, platelets THR -255.17±40.66, platelet volume MPV -7.81±0.19, platelet distribution width PDW-9.22±0.30, hemoglobin in erythrocytes MCHC - 27.29±0.29. The breed is a reliable (p<0.01) source of variation of LDH, with higher values found in the East Bulgarian breed (EBB). The mares of different ages can differ significantly (p<0.05) in the content of Mon in the blood. The age group in the breed had a significant effect (p<0.05) on Ca and PDW, with the oldest mares from EBB (10-12 years old) had decreasing amount of Ca and increasing amount of POW.

Currently, the extinction of donkeys (Equus asinus) worldwide is very limited, but donkey milk is recently getting popular in many countries due to its nutritional properties and chemical composition. For this reason, in our country, the farmers are encouraged to keep, to raise and increase the number of donkeys in their farms. Milk and donkey products are niche products, consumed by a small number of people, especially people suffering from various diseases (e.g. food allergies, children to whom breast milk should be substituted with milk similar in composition). Donkey milk brings benefits to consumers due to its chemical composition. Donkey milk storage depend on the chemical composition, antioxidant capacity and the biochemical degradation under heat treatment.

Sprat is a small pelagic species, with a key-role in the marine ecosystem, acting as a link between plankton and production on higher trophic levels. Sprat individuals collected from stations along the Romanian Black Sea coast were measured and weighted and the food array was performed by analyzing the stomachal content. Sprat fed on a broad diversity of mesozooplankton components, such as copepods, cladocerans and meroplankton. Analyzing the mesozooplankton component, copepods and meroplankton represented the bulk of the community in the area. Variability in zooplankton abundance may create a pressure on the feedıng conditions for sprat populations.

The relationship between the parity, the litter weight (LW) and some placental traits with goats was investigated in this study. 94 goat were investigated in total, 28 of which from first parity, 27 from second parity, 15 from third parity, 12 from forth parity and 12 from fifth parity. One-way ANOVA was used for statistical comparison, and Pearson correlation was used to determine the relationships between the variables. The goats’ placenta from the first parity weighs the least and the forth parity’s placenta is significantly (P<0.05) the heaviest. Significant differences in placental efficiency between the investigated animals were not discovered. Positive correlation was discovered between the weight of the placenta and the birth weight of the kid in the first, second and fifth parity. The results of this study show negative correlation between the weight of the placenta and the density of the cotyledons in goats of the first, second, third and fifth parity. Further studies are required to investigate the relationship between parity and placental traits in goats.

During the years 2019-2020, research was carried out on the assessment of the health status of fish in the upper Danube sector of Romania. Fish species belonging to the families Ciprinidae, Siluridae, Esocidae, Percidae, Clupeidae and Acipenseridae were analyzed. Fish were sampled from two stations: Station 1- km 1048, near Moldova Nouă and Station 2- km 493, near Giurgiu. The parasitological analyzes were performed in the laboratory of the Institute of Research and Development for Aquatic Ecology, Fishing, and Aquaculture (ICDEAPA), Galati, Romania. Analyzes were performed on fresh fish using well-known methods. In station 1, 14 species of parasites belonging to eight systematic groups were identified: Nematode, Monogenea, Trematode, Ciliata, Acanthocephala, Protozoa, Cestoda, Crustacea, while in station 2, 11 species of parasites belonging to six systematic groups were identified: Monogenea, Ciliata, Trematoda, Nematoda, Acanthocephala, Cestoda. The species Sander lucioperca and Abramis brama presented most often polyparasitoses but with a low degree of infestation. The most present group of parasites in station 1 was represented by nematodes and in station 2 by monogenic worms.

The aim of our study was to investigate the relationship between some placental parameters such as Placental weight (PW), Cotyledon number (CN), Placental efficiency (PE) and Cotyledon density (CD), as well as the Litter weight (LW) with the genotype of goats, type of birth and the gender of kids. The study was conducted in the goat farm of the RIMSA, Troyan, Bulgaria. The study involved 94 goats of 53 Bulgarian White Dairy breed (BWD) and its crossbreeds with Anglo-Nubian (AN)21 and Togenburg (TG)20. The results showed that PE in goats BWD was significantly higher compared to BWD x AN, BWD x T. There was a strong downward relationship between PW and PE. A significant downward relationship between PW and CD was found in all three genotypes. The PW of twins is higher than that singles (p<0.01). The total CN in twins is higher than in singles (p<0.01). A significant positive relationship was found between PW and LW in all studied genotypes and was highest in BWD x AN (p>0.05). A significant positive relationship was found between PW and the total CN in BWD.

Food poisonings can be lethal situations for digestive tractus, caused by ingestions of food contaminated with microbial germs or with theirs metabolic products. In this paper there were determinate bacteria from Salmonella genus, on the following types of samples, harvested from slaughterhouses and outlets: poultry and bird organs (thighs, gizzard and hearts and bird carcass), raw pig meat (pork neck, pork ribs and pork ham), processed pig meat (mincemeat and sausages). From analysed samples there were isolated: S. enteritidis, S. infantis, S. enterica, S. tennessee, S. saintpaul, S. bredeney, S. typhirium and S. muenchen. 50% of these bacteria were found in processed pork meat samples, followed by poultry and pork meat (raw meat), with 25% each. The isolation and identification technique was done with horizontal method, following these steps: pre-enrichment in unselective liquid mediums, enriching in selective liquid mediums, isolation and identification, identity confirmations

Scientific studies show that the darker the honey, the higher its bio-active properties are. Fallopia japonica (Japanese knotweed) is an invasive plant, growing shrub reaching heights of 3 m. Flowering occurs in late summer, when small, greenish-white flowers develop in long panicles in the axils of the leaves. Plants are dioeciously with flowers intensely visited by the bees, the honey obtained from nectar of this plant being a mild-flavored version of buckwheat honey; dark in color, appearing dark red when held to light. The present study aim to determine the chemical composition of Japanese knotweed honey and also their bioactive properties derived from the chemical composition. Different physicochemical, gravimetric, spectrophotometric and chromatographic determinations were used in the study. Analyzed honey samples are very good sources of minerals, especially K and Na (1187-6196 mg/kg K and 58.8-68.8 mg/kg Na). Also high amounts of Ca were determined. High amounts of total polyphenols and flavonoids were determined in Japanese knotweed honey samples, from several western places of Romania. This could reduce the impact that Fallopia japonica invasive plant have on the habitat, and if this plant is kept under observation and far from the inhabited areas, it could be highly valuable for beekeepers and honey production.

The blue crab, Callinectes sapidus (Rathbun, 1896), is native to the Western Atlantic, supporting extensive fisheries and more recently aquaculture pursuits. It has become established as a non-native species in the Mediterranean, while in the Black Sea it was first reported decades ago, near the Bulgarian coast. A first specimen was collected at the Romanian coast in 1998 and, since then, individuals of this species have been reported several times. Due to its high market value and potential for aquaculture, we investigated the adaptation of the blue crab to captivity conditions. One adult was caught in fishing nets in the Mamaia Bay and transported to NIMRD’s aquaculture laboratory. The crab was sexed (male) and measured (carapace width = 205 mm; carapace length = 100 mm; biomass = 537.58 g), and subsequently placed in a small PAS (pump-ashore system). Live mussels were introduced in the tank and the C. sapidus specimen was immediately observed feeding actively with the mollusks. Additionally, small fish were offered, being rapidly consumed. The overall observed behavior in captivity encourages aquaculture endeavors for this valuable species.

The research on the manufacturing process and characterization of Centella asiatica dried extract by adding lactose was carried out. The ratio of “pegagan” extract to lactose is 2: 1; 1: 1; and 2: 3. Products in the form of dry extract can be used as feed additives in poultry feed formulas. The results showed that the ratio of “pegagan” extract to lactose in the ratio of 2: 1, obtained the best dry extract “pegagan”flour character. The results of the characterization of dried “pegagan” extract are: shrinkage levels of 1.52%. total ash content of 1.17%, acid soluble ash content of 0.95%, water soluble compound content of 83.32% and organic solvent soluble compound content of 13.01%. Based on the results of the characterization test, “pegagan” dry extract flour can be classified as a feed additive in poultry feed formulas.
