R Alders, J de Bruyn, K Wingett, J Wong
Achieving ecologically sustainable food systems for people and animals is one of the greatest challenges facing our world today. Four interdisciplinary approaches that promote a holistic, systems approach to disease prevention and food security are introduced. Current domestic and international initiatives that link disease prevention with food and nutrition security are presented, with an emphasis on animal-source food and examples from Australia, Tanzania and Timor-Leste. Veterinarians are uniquely placed to use their training in comparative physiology in support of the production of sustainable, nutritious, ethical and safe food delivered with minimal waste to promote human, animal and environmental health...

T F Scheelings, R F Slocombe, C Bayley
CASE REPORT: Two cases of metastatic mineralisation caused by dietary excess of vitamin D are reported in hand-raised short-beaked echidna (Tachyglossus aculeatus) puggles at the Australian Wildlife Health Centre. Oversupplementation was attributed to excessive levels of vitamin D in Wombaroo Echidna Milk Replacer fed to the puggles. No information exists regarding the naturally occurring vitamin D levels in echidna milk, but, given the low serum levels that have been observed in free-ranging animals, it is likely to be low...

CASE REPORT: Clinicopathological features of neuroaxonal dystrophy (NAD) in newborn, Merino-Border Leicester × Polled Dorset lambs are described. The affected lambs were unable to walk at birth and microscopic examination of brainstem and spinal cord sections revealed bilaterally symmetrical accumulations of axonal swellings (spheroids), the histological hallmark of primary NAD. The neurological deficit was also exacerbated by myelin loss and secondary axonal degeneration, particularly in the spinal cord and sciatic nerves, but also, to a more limited extent, in brainstem and spinal nerves...
