Improving Inclusivity in the Curriculum via the Introduction of an Equine Industry-Specific Language eGlossary. The equine veterinary profession is frequently considered inaccessible to veterinary students who have had limited exposure to the equine industry. One of the perceived reasons for this inaccessibility is the use of what is often coined "horsey" language within the industry. If a student has limited experience of the equine industry, there is a potential language barrier to teaching, which may result in poor engagement with equine teaching and placements. The aim of this Teaching Tip is to describe the development and evaluation of a new teaching resource designed to demystify equine industry-...

Could snort production reflect comfort in horses kept outdoors? A first study. The welfare of free-roaming, captive wild or domestic animals housed outdoors is often questioned. How subjects perceive climatic conditions is not always well detected as it is highly subjective, depending on species, age and experience. Hence, decisions on housing rely mostly on human anthropomorphic perception. In particular, indicators of comfort and positive emotions remain poorly documented. Acoustic signals, however, offer a promising window into animals' internal states. In the present study, we hypothesized that acoustic signals could be used to identify positive or negative perceptio...
First evidence of exposure to West Nile Virus in horses within Denmark, 2025. A nationwide serological screening of 822 horses was conducted in Autumn 2025 to investigate potential exposure to West Nile Virus (WNV) within Denmark. Serum samples were tested for antibodies against WNV, tick-borne encephalitis virus (TBEV) and Usutu virus (USUV). Four horses without any history of travel outside of Denmark, or previous vaccination against WNV, tested positive for WNV neutralising antibodies. The results support local exposure to WNV indicating that virus infected mosquitoes have been present in Denmark and underline the usefulness of horses as sentinels for the risk of hum...
