Blood analyses can be used to assess the health and physiological conditions of wild animals and may provide a precise picture of disease, habitat quality, and other environmental factors. The objective of this study was to analyze the relationship between the age and the selected biochemical parameters of the female mouflon (Ovis musimon L.). This study creates a possible reference range of biochemical parameter concentrations in mouflon and aims to extend the knowledge of this wild game species within our geographical region. There have not been many studies dealing with this issue in our geographical region. A total of 57 female mouflons aged between 1 and 6 years (1–3 years n = 32, 4–6 years n = 25) and in good physical condition, with an average live weight between 32 and 40 kg were included in the research experiment between the two years. A total of 15 selected biochemical parameters were analyzed. Using statistical analysis, we noticed significant effects of age on almost three-quarters of analyzed biochemical parameters. A statistically significant correlation was observed between age and the parameters of glucose, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, bilirubin, cholesterol, creatinine, high-density lipoprotein, calcium, triglycerides, and urea. An evaluation of the European mouflon’s biochemical parameters during the whole year may be a reliable method for judging a herd’s condition, diagnosing medical disorders, and preventing the etiology of their occurrence. An analysis of biochemical parameters tells us about the functioning of individual organs as well as the animals’ metabolism. Knowledge of the values of blood parameters is of special importance because they allow us to gather more information on mouflons.

Population grows fastest in the world’s urban and metropolitan cities, the number of inhabitants in so-called metropolitan cities and in urban and suburban zones are expanding into the surrounding natural landscape. Consequence of these changes is the gradual displacement of natural greenery and nature from cities and newly created residential satellites designed to build residential and public amenities. In recent years, is more commonly used sustainable development phenomenon which has become as a responding trend to of cities and municipalities and the implementation of so-called urban gardens intended for growing crops within the communities of the population. In view of mentioned facts the presented article focuses on ecological urban agriculture in terms of the main components of sustainability as an element contributing to the sustainable development of cities and suburban zones.

Introduction. The safety of poultry meat products and contamination with microorganisms is based on appropriate reduction of the presence of pathogens during poultry rearing and is closely related to the level of rearing hygiene, including the type of housing, stocking density, microclimate, sanitation and ventilation. Objective. The aim of the study is to evaluate the prevalence of Campylobacter-positive samples in Iceland during 2016-2018, and to compare the potential influence of individual parameters of welfare on the prevalence of Campylobacter spp. Materials and method. Positivity of excrement and caecum samples for Campylobacter spp. was determined according to ISO 10272-1: 2006 and 2017. Data of welfare indicators were collected during the rearing period and in the slaughterhouse. Results. Considerable seasonality was observed in the prevalence of Campylobacter spp. The prevalence of campylobacteriosis on the investigated broiler farms was significantly higher (p˂0.05) during the summer. Comparison of welfare parameters on Campylobacter-positive and Campylobacter-negative farms failed to indicate a significantly higher level of observed welfare indicators in birds from Campylobacter-positive farms (p˃0.05). In comparing small, medium and big farms, a significantly higher occurrence was observed (p<0.05) of the FPD score over 40, stocking density, and the average slaughter weight, and percentage of mortality over 2% in small farms. Conclusions. Intensive management and the environment affect the welfare of poultry and its resistance to infections (Campylobacteriosis) and thus increase the health risk. Checking the welfare parameters in a slaughter house provides delayed improvement of the environment on farms, but it can also lead to changes in the following production cycles (decreasing of stocking density).

Biochemical analysis in horses is an important aid for determining correct clinical diagnosis of general, infectious, and some parasitic diseases. This work studied the biochemical and mineral indices in mares of two breeds: the Norik breed Muráň Plain type and the Hucul breed. A total of 34 mares of the Norik breed Muráň Plain type (aged 15.18 ± 5.99 years) and 28 Hucul mares (aged 9.03 ± 5.50 years) were used. Blood serum was analysed using the biochemical analyser Cobas c111 (Roche, Switzerland). Significant difference (P < 0.05) was found between the Norik breed Muráň Plain type and the Hucul mares in aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase and gamma-glutamyltransferase activity; significant difference (P < 0.01) was found in urea values; and highly significant difference (P < 0.001) was found in glucose values. The mineral profile elements showed a highly significant differences (P < 0.001) between the Norik breed Muráň Plain type and the Hucul mares in phosphorus, magnesium, iron, chloride, potassium, and sodium concentrations. The results confirmed that there are significant differences between horse breeds in some biochemical indices. Therefore, it is appropriate to determine reference values for other horse breeds, as well. To our knowledge, this is the first report that compares biochemical and mineral indices between the Norik breed Muráň Plain type and the Hucul breed.
