Genotyping of 114 stud bulls of local and specialized dairy breeds based on the beta-casein gene has been carried out. According to the results of the research, it is found that the highest frequency of the A2A2 desired homozygous genotype is characteristic of local cattle of Lebedyn breed and OBV (56%), as well as stud bulls of the Ukrainian White Headed breed (50). A significant difference in the frequency of genotypes for this trait has been established between individual breeds. The creation of micro-populations of cattle based on beta-casein with the A2A2 desired homozygous genotype makes it possible to obtain milk that has a number of properties, which are not characteristic of ordinary milk. Thus, the increased frequency of the A2A2 genotype for beta-casein may contribute to the conservation and spread of local breeds on Ukrainian farms.

The aim of this study was to evaluate the impact of different phytogenic compounds on the haematological profile and biochemical indices of carp, reared in a recirculating pilot aquaculture system. The experiment was conducted for 52 days. A basic feed, Aqua Classic type, with 46% protein and 22% lipid, was used. 5 g of different phytogenic compounds were added to form the experimental diets, as follows: V1 - control, V2 - 0.5% licorice (Glycyrrhiza glabra), V3 - 0.5% echinacea (Echinacea purpurea) and V4 - 0.5% wild thyme (Thymus serpyllum). At the end of the experiment, blood samples were taken to evaluate the haematological and blood biochemical parameters. The mean values for Ht, Hb, RBC and WBC were higher in the experimental variants than in the control. Serum protein was significantly lower (p<0.05) in variants V2 and V3 compared to the control. The serum glucose values registered significant differences between the control and the 3 experimental variants. In conclusion, the addition of phytogenic compounds in the diet has beneficial effects on the haematological and blood biochemical profile of carp (Cyprinus carpio).

As a result of the study of 10 specimens Perca fluviatilis Linnaeus, 1758 and 10 specimens Vimba melanops (Heckel, 1837) from the Maritsa River, Aegean water basin, Bulgaria, infection with 5 helminth species are presented (Allocreadium isoporum (Loos, 1894); Proteocephalus percae (Müller, 1780); Caryophyllaeus laticeps (Pallas, 1781); Contracaecum sp., larvae and Acanthocephalus lucii (Müller, 1776)). All identified parasite species are autogenous to the parasite communities of the perch and Macedonian vimba, except Contracaecum sp., which is an allogeneic species. Infection indices are discussed and pathways of helminth flux circulation are traced. The dominant structure of the helminth communities was analyzed. New data on the helminths and their communities in the two species of freshwater fish, as well as on the ecological status of the studied biotopes of the freshwater ecosystem are presented.

This paper is a comprehensive study of the strategic approach, in the context of global population growth, to create more food using current natural resources. Integrated multi-trophic aquaculture (IMTA) can provide aquaculture products in much larger quantities using the same resources involved. Harnessing all the waste in the waters for this purpose brings multiple environmental and economic benefits. In the context of the circular economy, IMTA principles aim to significantly reduce waste and degrade the environment, but without restricting economic and social progress. In Romania, polyculture fish farming is practised to exploit all aquatic resources in fish farms. Each fish species is selected so that it can be nutritionally supported with natural feed from the environment, and various types of feed can be used to increase production. The results of the study can be used to improve the aquaculture development strategy, in the environmental sustainability context.

The behaviour of the mother goat plays a decisive role in the survival of the newborn kid. There are conflicting opinions regarding the influence of temperament on maternal behaviour in different animal species. In goats, as species that possess a behaviour of "hiding" their newborn, temperament should significantly influence the development of the relationship between the newborn kid and its mother. This is especially important in animals giving birth for the first time. Knowing the relationship between temperament and maternal response in goats would lead to better management of technological processes on the farm, which in turn would increase kid survival rates and reduce mortality rates. Various tests are used worldwide to determine the temperament of farm animals, some of which are applicable to goats. The aim of this review is to summarize the methods of determining temperament in dairy goats and how it affects the goat's behaviour towards the kid.

This study refers to the common carp (Cyprinus carpio), which is an adaptable species that enriches the variability of quantitative and qualitative characteristics and increases genetic diversity. Local aquaculture populations of common carp, called "landraces," have developed due to different environmental conditions and breeding efforts. However, the introduction of carp in some areas has led to negative impacts on natural aquatic ecosystems. To improve the quality of economically important fish species, the variation in morphological, physiological, and biochemical characteristics is utilized. In this study, a patent application for a system for reproduction, selection, and growth of fish fry with the simulation of natural conditions is described. The article explains the method used to replicate the natural aquatic environment and create viable products with high genetic adaptability to its conditions. The process falls into the category of extensive aquaculture, promoting sustainable aquaculture by increasing the percentage of ecological and environmentally friendly productions. The study concludes with the results and the development of a set-up of the station for laboratory use.

The objective of this work was twofold: i) to characterise the main applications of the life cycle assessment (LCA) for assessing and representing mixed farming systems (MFS), and then ii) to propose a general methodological framework for conducting a comparative LCA of a case study of an MFS versus a specialised system in Romania. For this purpose, the main applications of LCA to MFS have been analysed in all its phases. Overall, the reviewed LCA studies highlighted the potential of MFS to improve environmental sustainability, but scarcity of real data hindered the assessment process. In addition, some studies focused on a single product rather than taking into account all products (crops and livestock) when comparing MFS with specialised ones. This may exclude interactions between farm components in the MFS and therefore may not reflect the overall impact of these systems. Therefore, an LCA based on a farm-level approach is recommended to provide a fairer comparison of MFS versus specialised systems.

The White Stork (Ciconia ciconia) is one of the only two taxa representatives of the Family Ciconiidae (Storks) that nest in Bulgaria. The species is protected both on the territory of the country and the EU, and is included in the subject and conservation objectives of many SPAs in the country, part of the European ecological network NATURA 2000. In this paper we present the number, etiology, condition and treatment outcome of over 2,900 specimens of the species accepted for treatment in the period 1999 - 2021. These are patients of the Green Balkans Wildlife Rescue Center in Stara Zagora, which is leading unit for ex-situ conservation of wildlife protected and rare bird species not only in the country but also on the Balkan Peninsula. The outcome of the treatment of all white storks is presented in 4 main categories – returned to nature, housed for aviary breeding, redirected to other ex-situ structurers, as well as lethal outcome. We evaluated the influence of different etiological factors, age and season on the treatment outcome.

Palynological research has applicability in several scientific fields, the most important being taxonomy, plant evolution, medicine and the analysis of honey - melissopalynology. The palynology provides data regarding the botanical and geographical origin of bee products like bee pollen, bee bread, royal jelly and propolis, which is useful in establishing their provenance and correct labelling. This paper details the characteristics and investigation of several methods for obtaining microscope slides from different bee products. The microscopic examination represents an essential part of the palynological analysis. Several methods for the preparation of microscopic slides were selected and assessed regarding preparation time, costs, dangerous substances used and results. The methods were employed successfully for different bee products, but the non-acetolysis method published by Louveaux et al. (1978) offers several advantages in terms of ease of use, safety and efficiency. The results of our comparative analysis emphasize that some methods are recommended for the creation of reference libraries, while others are well suited for being used in routine analysis of bee products.

This research aims to confirm and quantify the presence of mineral oil hydrocarbons (MOHs) in feed, as well to investigate the contribution of modern pollution sources to the level of contamination. Through simultaneous processes of microwave assisted saponification (MAS), extraction and purification procedures, followed by the LC-GC-FID detection, 8 types of feeds from one of the most polluted areas of the country were analyzed. The results indicated contamination with MOH for most of the feed samples, mineral oil saturated hydrocarbons (MOSH) concentrations above the recommended limits (0.5 mg/kg) being recorded. The data indicated moderate to high contamination for MOSH, from 16.5 mg/kg to 77.3 mg/kg, while average values below the limit of quantification (< LOQ) were highlighted for mineral oil aromatic hydrocarbons (MOAH) content. Based on the results, was difficult to establish a clear relationship between feed contamination, crop location and different pollution sources. However, the information obtained by assessing the relationship between feed contamination and pollution, indicated that the pollution sources from the plotting area had an important contribution to the contamination of the analyzed feedstuffs.
