    Differences between pet rabbit and farm rabbit welfare
    (Eesti Maaülikool, 2024) Neeve, Henri; Arney, David Richard (advisor); Carnovale, Francesca (advisor)
    The welfare differences between pet rabbits and farm rabbits involve various aspects of animal husbandry, such as housing, feeding, social needs and environmental conditions. Since rabbits are naturally social animals, who typically live in groups, they can experience several problems related to anxiety and stress due to loneliness in domestic settings. Anxiety and stress can lead to numerous health and behavioural issues in rabbits, such as aggression and self-harm (inclucing pulling out their own fur). The aim of this study was to identify the welfare and health problems that occur most frequently in both pet rabbits and farm rabbits, as well as to find possible solutions for these issues. The results revealed that pet rabbits had a greater variety of diseases and health disorders compared to farm rabbits. The difference could be attributed to the intensive farming practices, where many farm rabbits do not live beyond 12 weeks of age, thereby avoiding age-related health issues. Pet rabbit owners also visit veterinarians for more frequent check-ups, providing early detection and more specific categorization of various diseases. This study highlights the need to improve rabbit welfare by considering their natural needs in both home and farm environments.

    Impact of noise on European mink (Mustela lutreola) behaviour
    (Eesti Maaülikool, 2025) Zarja, Aleksandra; Arney, David Richard (advisor); Nemvalts, Kristel (advisor); Kiik, Kairi (advisor)
    Due to increasing urbanisation, the impact of noise on living organisms can be a major welfare issue. It has been shown that anthropogenic noise can cause health problems in many animals. Particularly important is to define the impact of noise to endangered species such as the European mink, whose wild population survival is highly influenced by the successful reproduction of the captive population, which in turn is influenced by the environmental conditions of artificial environment. The aim of this bachelor's thesis was to examine whether noise exposure during public events affects the behaviour and activity patterns of captive European mink. This research was conducted on 14 adult male European mink. The observation period was divided into four nights before the event (control period), two nights during the event (high noise period), and four nights following the event (recovery period). All analyses were performed within the RStudio environment, using a linear mixed model. The results indicated that stereotypic behaviour decreased significantly during noisy event. Total activity declined in the days after the event. Accordingly, the event had a significant delayed impact on the activity, and it suggests that noise exposure not only decreases movement in general, but it could also inhibit adaptive behaviour by temporarily suppressing stereotypical behaviours. The obtained results provide a foundation for future research on the European mink.
