BACKGROUND Bovine spongiform encephalopathy (BSE), a member of the transmissible spongiform encephalopathies (TSE), primarily affects cattle. Transmission is via concentrate feed rations contaminated with infected meat and bone meal (MBM). In addition to cattle, other food animal species are susceptible to BSE and also pose a potential threat to human health as consumption of infected meat prod...
Male Rocky Mountain elk (Cervus elaphus nelsoni) produce loud and high fundamental frequency bugles during the mating season, in contrast to the male European Red Deer (Cervus elaphus scoticus) who produces loud and low fundamental frequency roaring calls. A critical step in understanding vocal communication is to relate sound complexity to anatomy and physiology in a causal manner. Experimenta...
To illustrate the most important sources of venison (deer meat) in the world, the examples in this article are taken from the deer farming industry in New Zealand and the traditional reindeer husbandry cultures in Fennoscandia (Sweden, Norway, and Finland) and Alaska (with roots in Russia and Fennoscandia). These deer industries are mainly focused around pasture-based venison production systems...
The patterns of genetic variation of present-day European terrestrial fauna and flora have been influenced by repetitive fluctuations between major glacial and interglacial climatic cycles that have occurred during the Quaternary period (Hewitt, 2004, and references therein). The isolation of species into one or more refugia during the glaciations (Hewitt, 1996) and the mode of post-glacial col...
The aim of this study was to measure the relative susceptibility of three age classes of red deer (Cervus elaphus) to the various manifestations of infection and disease states due to Mycobacterium avium subsp. paratuberculosis (MAP) after experimental oral challenge. Three groups of seronegative female deer (30 three-month-old weaners, 20 fifteen-month-old yearlings and 20 adults) received fou...
