Background: Reducing antimicrobial resistance (AMR) requires a multidisciplinary One Health approach, which necessitates buy-in from all stakeholders. In Aotearoa New Zealand, where the dairy industry is one of the largest users of antimicrobials, there are ongoing efforts to optimise antimicrobial usage (AMU) to minimise the development of AMR. These include regulations around the veterinary authorisation of the use of antibiotics by farmers without the need for a specific prescription ("the RVM process") and programmes such as the New Zealand Veterinary Association's antibiotic 'Traffic Light System'.

Background: Heat treatments of dairy, including pasteurization and ultra-high temperature (UHT) processing, alter milk macromolecular structures, and ultimately affect digestion. In vitro, animal, and human studies show faster nutrient release or circulating appearance after consuming UHT milk (UHT-M) compared with pasteurized milk (PAST-M), with a faster gastric emptying (GE) rate proposed as a possible mechanism.

Objectives: To investigate the impact of milk heat treatment on GE as a mechanism of faster nutrient appearance in blood.

Article Synopsis
  • The study aimed to assess the recovery prospects of injured Thoroughbred racehorses diagnosed with palmaroproximal metacarpus issues using MRI, involving 29 horses at the Hong Kong Jockey Club from 2014 to 2022.
  • Overall, 92% of horses returned to galloping and 67% to racing, with a low reinjury rate of 18%, primarily affecting those with concurrent injuries to both the proximal suspensory ligament (PSL) and proximal third metacarpal (MC3) bone.
  • Horses with both injuries had a longer recovery time before returning to galloping compared to those with only PSL injuries, indicating the need for more extended rehabilitation in such cases.

Epidemiology is often a challenging course that is not well appreciated by many students learning veterinary medicine. The curriculum for this topic can sometimes be dry, difficult for students to contextualize, and heavy with statistics and mathematical concepts. We incorporated the concepts of epidemiology that are most important for practicing veterinarians and combined these with evidence-based veterinary medicine principles to create a practical course for second-year undergraduate veterinary students.
