  • One Health, veterinarians and the nexus between disease and food security

    Thursday, Nov 9 '17 01:30

    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.

  • Examination of the use of intraovarian administration of CaCl2 and zinc gluconate as potential chemosterilants in Bos indicus heifers

    Friday, Oct 27 '17 04:03

    Objective To investigate if administration of potential chemosterilants by transvaginal, ultrasound-guided intraovarian injection is an alternative to surgical sterilisation. Design Randomised control study. Methods Bos indicus heifers were treated with intraovarian injections of saline (n = 10), CaCl2 (n = 10), zinc gluconate (ZG; n = 10) or a combination of CaCl2 and ZG (CaCl2 + ZG; n = 10). Heifers were exposed to a bull from 82 to 84 days after treatment and slaughtered between 364 and 396 days after treatment. Results After treatment administration, the concentrations of haptoglobin and anti-Müllerian hormone and the total oocyte counts did not differ (P > 0.150) between treatments. Pain responses were observed in heifers treated with ZG and CaCl2 + ZG but not in heifers treated with saline or CaCl2. Total ovarian mass at slaughter was less in heifers treated with CaCl2 compared with the other treatments (P < 0.05). Complete regression of one ovary was observed in 40% (4/10) of the heifers treated with CaCl2. Pregnancies were recorded in ≥ 70% of heifers administered each treatment. Conclusion Treatments used in this study were not able to sterilise most of the B. indicus heifers, but treatment with CaCl2 has the potential to cause complete ovarian atrophy without causing detectable pain.

  • Metastatic mineralisation caused by vitamin D intoxication in hand-raised short-beaked echidnas (Tachyglossus aculeatus)

    Friday, Oct 27 '17 04:03

    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. Conclusion The vitamin D concentration in Wombaroo Echidna Milk Replacer has been reduced. Read more...
