Questionnaires were posted to 800 randomly selected registered Victorian dairy farmers in 1996. Five hundred and thirty-four responses were received and analysed. Johne's disease (JD) had been diagnosed on the farm of 13.2% of respondents in the last 5 years. JD was rated second only to neonatal diarrhoea in importance as a disease of calves, even though other diseases occurred more frequently. However, there was a low level of compliance with JD control recommendations by the respondents. There was no significant difference in the number of JD control recommendations adopted by farmers between the three major Victorian regions. There was a significant difference in compliance between farms having had a diagnosed case of JD and those that had not. Although there is awareness among dairy farmers of the importance of JD, there appears to be a poor implementation of measures by farmers to prevent the spread of the disease. Current JD control recommendations and the method of information transfer to Victorian dairy farms should be reassessed to ensure that dairy heifers are reared with minimal risk of transmission of JD.

Fecal egg counts and individual milk production in temperate pastoral dairy systems of Australia.
JDS Commun
November 2024
Melbourne Veterinary School, Faculty of Veterinary Science, University of Melbourne, Werribee, VIC 3030, Australia.
Article Synopsis
- Anthelmintic treatment in lactating dairy cattle may improve milk production, but optimal use depends on identifying which cows benefit most, potentially reducing drug resistance.
- An observational study in south-west Victoria found no significant difference in milk production between cows with low and elevated fecal egg counts (FEC) shortly after calving.
- The variability in FEC and milk yield across farms indicates that individual FEC results might not effectively identify cows that need anthelmintic treatment in these pasture-based dairy systems.
Collaborative Development of a Farm Systems Learning Platform "4D Virtual Farm".
J Vet Med Educ
February 2024
Animal Production at the Melbourne Veterinary School, Faculty of Science, University of Melbourne, 3010, Victoria, Australia.
Article Synopsis
- Over the past two decades, fewer veterinary and animal science students in Australia and New Zealand have experience with livestock production, prompting a need for new educational methods.
- The 4D Virtual Farm was developed to allow students to explore 11 different types of livestock farms across Australasia through digital technology, simulating seasonal operations.
- This platform can be accessed via various devices, and serves as a versatile educational tool for instructors to demonstrate production systems and facilitate self-directed learning for students.
Early life events associated with first lactation reproductive performance in southwest Victorian pasture-based dairy herds.
Aust Vet J

Apiam Animal Health, Smithton Veterinary Service, Smithton, Tasmania, Australia.
This was a prospective cohort study to determine how events from birth until first calving affect reproductive performance in the first lactation in pasture-based dairy herds in Victoria, Australia. Events during the preweaning (0 to 84 days), weaning to first breeding (85 to 473 days) and first breeding to first calving periods (474 to 804 days) were recorded and their association with reproductive performance during the first lactation was quantified. Reproductive performance outcomes included the number of days from first mating start date to first service (MSD-S1) and the number of days from first mating start date to first conception (MSD-CON).

Context: Dietary fibers hold potential to influence depressive and anxiety outcomes by modulating the microbiota-gut-brain axis, which is increasingly recognized as an underlying factor in mental health maintenance.
Objective: Evidence for the effects of fibers on depressive and anxiety outcomes remains unclear. To this end, a systematic literature review and a meta-analysis were conducted that included observational studies and randomized controlled trials (RCTs).
An analysis of substantiated complaints made about incidents of poor livestock welfare, in Victoria, Australia.
Front Vet Sci
August 2023
Animal Welfare Science Centre, Melbourne Veterinary School, Faculty of Science, University of Melbourne, Parkville, VIC, Australia.
Incidents of poor welfare on farm in Victoria, Australia, are generally identified during an investigation that follows receipt of a complaint. Using deidentified records of complaints received by the Victoria State Government between 2011 and 2020, this study aimed to describe the source, number and the relationship between rainfall/stock prices and substantiated welfare complaints (SWC). Only incidents involving non-dairy cattle, sheep and goats in extensive farming systems will be considered.
