    Domestic animal homelessness is a long-known and ever-present phenomenon in Poland. Left unattended, animals pose a threat to people, their farms, public order and epidemiological safety. “The problem” was attempted to solve as early as the 19th century. Although the main purpose behind catching stray dogs was the need to remove them from public space, attention was drawn already in distant times to issues related to improper and brutal handling during the catching, transporting, keep- ing and killing of unwanted pets. Nowadays, animals entering shelters can no longer be killed, but the problem of their homelessness is still present and has not been effectively resolved over the years. Changes in the political system and regulations have not guaranteed that they are properly protected and cared for in shelters, as there are still cases of inhumane treatment of animals in these facilities. There have also been no effective solutions to significantly reduce the scale of the phenomenon of dog abandonment in Poland. The lack of an obligation to sterilize mixed-breed individuals means that there are a lot of them, so that any person can come into possession of a dog without any difficulty, which, combined with the lack of mandatory, permanent and enabling owner identification marking, means that there are still tens of thousands of stray dogs in Poland, and responsibility for their abandonment can easily be avoided. The aim of the study is to showcase changes in the treatment of stray animals that occured during the last century.

    Selenium content in the ovaries of free-liwing Cervidae from nordeastern Poland

    Selenium is counted among the trace elements necessary for the maintenance of metabolic processes occurring in the animal body, including the proper functioning of the reproductive system. The aim of the study conducted was to analyze the selenium content in the ovaries of red deer (Cervus elaphus) and European roe deer (Capreolus capreolus) in an attempt to establish a range of reference values for individuals of these species. Selenium concentrations in tissues tested were determined using spectrofluorometric method after wet mineralization in HNO3 and HClO4 mixture. Ovaries Se concentrations ranged from 0.034–0.338 mg⋅kg−1 wet weight and 0.015–0.285 mg⋅kg−1 wet weight in roe deer and red deer respectively. Based on the results, it was found that the average selenium content was higher in the ovaries of red deer and was 0.11 while in roe deer it was 0.09 mg⋅kg−1 wet weight. The gonads of European roe deer were characterized by higher variability of the analyzed pa rameter in relation to samples obtained from female red deer. The coefficient of variation in their case was almost 90.1, while the value of the coefficient of variation for selenium content in the parenchymal layer of ovaries in red deer was almost 67.6.
