Within veterinary ethics and practice around companion animal end-of-life and euthanasia, the political and cultural dimensions of death and dying are rarely addressed. This reduces the ability to engage with questions like: what future potential goods (positive affective states, meaning) could an animal experience by continuing to live; what constitutes a life worth living; and how can we make this decision for another being? These are questions that have been subject to extensive dialogue within Critical Disability Studies. The aim of this paper is to provide an analysis of how core considerations from Critical Disability Studies could be useful in veterinary ethics when considering companion animal end of life and euthanasia. First, critiques of the and associated hierarchies raise questions about how animal disability and illness are understood, and around challenging questions like psychological illness and behavioural euthanasia. Second, nuanced engagements with questions of and Quality of Life emphasise the importance of individual animal experiences, personality, and the foregrounding of 'what is important for the animal'. Third, dialogues around critique the tendency to focus on owner choice, rather asking what opportunities there are to listen to the preferences of animals themselves. Finally, engaging with highlights the ambivalent nature of caregiving, of euthanasia as a practice of care, and the power intrinsic to making End of Life decisions on behalf of another. Overall, perspectives from Critical Disability Studies allow us to engage with challenging questions of veterinary ethics and end-of-life care in companion animal practice with more nuance and complexity.

Marek's Disease (MD), which can result in neurological damage and tumour formation, has large effects on the economy and animal welfare of the poultry industry worldwide. Previously, we mapped autosomal MD QTL regions (QTLRs) by individual genotyping of an F population from a full-sib advanced intercross line. We further mapped MD QTLRs on the chicken Z chromosome (GGZ) using the same F population, and by selective DNA pooling (SDP) of 8 elite egg production lines.

While numerous studies have established correlations between parasite load and negative effects on their hosts, establishing causality is more challenging because parasites can directly compromise host condition and survival or simply opportunistically thrive on an already weakened host. Here, we evaluated whether Ixodes uriae, a widespread seabird tick, can cause a decrease in growth parameters (body mass, bill length and growth rates) and survival of chicks of a colonially seabird, the black-browed albatross (Thalassarche melanophris) breeding on New Island (West Falkland). To investigate this, we daily removed the ticks from 28 randomly selected chicks during their first 14 days of life (treated chicks) and compared their growth and survival with 49 chicks of a control group.

Background: Echinococcosis is a zoonotic disease caused by an Echinococcus tapeworm infection. While diagnostic methods for humans often rely on ultrasound imaging and immunodiagnostic techniques, diagnosis in intermediate hosts typically has no widely used diagnostic markers, hampering disease control efforts.
Methods: The differences in serum metabolites of sheep infected with Echinococcus granulosus and a control group were analyzed using ultrahigh-performance liquid chromatography (UHPLC) separation with tandem mass spectrometry (MS/MS) detection.

Background: The Anopheles funestus group includes at least 11 sibling species, with Anopheles funestus Giles being the most studied and significant malaria vector. Other species, like Anopheles parensis, are understudied despite their potential role in transmission. This article provides insights into the biology and insecticide susceptibility of An.

Background: The reproductive problem is an animal health-related bottleneck that constrains livestock genetic improvement efforts in tropical countries such as Ethiopia. The infectious causes of reproductive disorders are one cause of decreased reproductive efficiency. This study aimed to determine the seroprevalence to Bovine Herpesvirus-1 (BHV1), Bovine Viral Diarrhea Virus (BVDV), Neospora caninum (N.
