International organizations and the world scientific community note a growth of environmental processes associated with agricultural activities. In particular, it is recognized that sector deeply specialized (monoculture) production, which intensifies land degradation, has negative impact on environment natural resources. Losses from soil fatigue, companion to monoculture, amount almost 25% har...
In this paper, we assess the environmental impact of urbanization in three freshwater biotopes, using levels fluctuating asymmetry (FA) 10 meristic morphological traits Marsh Frog (Pelophylax ridibundus (Pallas, 1771)). Two studied biotopes are located boundaries city Plovdiv (one central part, other a suburban residential area), and third is vicinity village Orizare. Our working hypothesis bas...
The role of facilities and associated services for amphibians has recently undergone diversification. Amphibians traditionally used as research models adjust well to captivity and thrive with established husbandry techniques. However, it is now necessary to maintain hundreds of novel amphibian species in captive breeding, conservation research, and biomedical research programs. These diverse sp...
There is increasing evidence that the globe is currently warming, with changes being more pronounced in northern latitudes. Understanding the ecological effects of climatic variability is therefore important. There is recent support for the idea that a large-scale atmospheric phenomenon, the North Atlantic Oscillation (NAO), through its effects on vegetation and regional weather conditions, inf...
The objective of this study was to compare some husbandry procedures on the base of physiological stress parameters and evaluate the welfare status in sheep. Forty ewes were used as the study material. Measurements were taken during several routine husbandry procedures such as milking, shearing, weighing, loading and hoof care. Data regarding time spent for each application, as well as heart an...
It has traditionally been the responsibility of the animal science community to develop management, nutrition, health and well-being protocols for animals raised for production purposes. The vast array of scientific inquiry dedicated to production livestock have been instrumental in the management of these animals to optimize a value-based end product. Within the last several decades however, t...

Methods. Methods comparative analysis (including rating evaluation method), structural analysis, statistical systematization, generalization, analogy, comparison were used. Results. Using a number indicato...
The mammalian intestine harbors a vast, complex and dynamic microbial population, which has profound effects on host nutrition, intestinal function and immune response, as well as influence on physiology outside of the alimentary tract. Imbalance in the composition of the dense colonizing bacterial population can increase susceptibility to various acute and chronic diseases. Valuable insights o...
The poultry sector in the Netherlands is confronted with the EU ban on conventional cages, the public debate on the welfare of hens in furnished cages, the limited perspectives of currently used more welfare-friendly singleor multi-tiered systems (either indoor or outdoor), and with questions about the natural behaviour of animals and the robustness of current production systems. To arrive at n...
