Artificial intelligence for a dairy cattle heat tolerance phenotype
This study aims to enhance the selection of heat-tolerant dairy cattle by integrating artificial intelligence into the current model used to calculate the Australian Breeding Value for Heat Tolerance.
Factors influencing lactose production in dairy cows.
The study analysed almost 400,000 herd test records from more than 30,000 cows across 85 farms in New South Wales to assess the relationship between lactose output and milk yield, composition and quality, genetics, and environmental factors.
Potential of HSP70 as a non-invasive biomarker for detecting heat stress in dairy cow.
This study compared the effectiveness of heat stress detection methods, with a particular focus on HSP70, a protein in milk that has been identified as a potential non-invasive biomarker.
Investigating genotype and environment effects on the rumen microbiome.
Dairy UP is validating potential markers and technologies (sensors, AI, etc.) to quantify production responses and recoveries to rumen microbial imbalances.
Effect of drought on microbiome community and metabolite profiles in kikuyu.
This study investigated changes in the fungal community and metabolite profiles in kikuyu under conditions designed to replicate those that lead to kikuyu poisoning.
Understanding and predicting changes in nutritional value of Kikuyu
This study aimed to predict short-term (daily) changes in the nutritional value of kikuyu pasture regrowth. Kikuyu is a widely used grass that grows rapidly but its nutritive value declines quickly.
2025 DRF Symposium
The Dairy Research Foundation Symposium will be held on Wednesday 26th and Thursday 27th November 2025.
Welcome to Dairy UP
Dr Tori Alexander, Dr Laura Ruiz Espinosa and Dr Sarah Legge join the Dairy UP team.
Remote pasture sensing workshop
In February, more than 20 service providers, consultants and researchers attended Dairy UP’s remote pasture sensing workshop.
Milk with less lactose
Dairy UP’s P9a project is looking for ways to produce cows’ milk with high concentrations of solids and less water.
Markers for cow longevity
Results from Dairy UP PhD student, David Sheedy’s, work have been published in the Journal of Dairy Science. He is investigating biomarkers associated with increased aging and number of calvings (parity).
Amazing maize
Dairy UP’s P4 project (Feedbase – Maize for Silage) is progressing well. The team is currently working with Pioneer Seeds to evaluate the yield and nutritional characteristics of conventional and ‘brown mid-rib’ (BMR) hybrids grown under full irrigation at the University of Sydney “Lansdowne” farm in Camden.
Alice Shirley joins USYD after completing her PhD with Dairy UP
Dairy UP PhD student Alice Shirley, has been appointed to an ongoing education-focused role with the University of Sydney from May 2025, when she is due to complete her PhD candidature.
2025 Dairy Symposium – revised dates!
Four Dairy UP PhD students presented their work at the 20th Australasian Dairy Science Symposium in Christchurch in November, thanks to support from the University of Sydney Postgraduate Research scheme.

Resources for resilience
East coast low weather systems can be destructive by causing flooding, but they are also very beneficial by providing 20% of annual rainfall over a wide area of the NSW coast. LLS agronomist and Dairy UP team member.
Resilient cattle
Dairy UP’s P6a Project is exploring the diversity in dairy cattle responses to heat events with the view to providing data to refine the model used to calculate DataGene’s Heat Tolerance Australian Breeding Value (ABV).
Satellite monitoring insights
Satellite technologies are improving all the time, creating new and exciting opportunities for remote pasture monitoring.
2025 Dairy Symposium
The Dairy Symposium will be held in November 2025
The hidden cost of pasture utilisation
Dairy UP’s work has recently been under the spotlight with an article ‘The hidden losses of pasture utilisation’ recently published in The Australian Farmer. The article features project P1a Remote pasture monitoring.
