Are nutrient losses from pasture-based dairy systems of concern, and can they be mitigated? Find out in the in an article from an international Lincoln University, Ulster University, University of Auckland - Waipapa Taumata Rau, Teagasc Dairy, and INRAE team led by Richard McDowell 👉 https://doi.org/10.3168/jdsc.2025-0934

Highlights
✅Nutrient losses to freshwater depend on sources and transport pathways.
✅Urine patches dominate nitrate-nitrogen leaching in pasture-based systems.
✅Dung and soil are primary phosphorus sources lost via surface runoff.
✅Actions must be nutrient specific and range from farm system to edge-of-field.
✅Targeting actions to critical source areas increases cost-effectiveness.

Is pasture adequate and what is the role of supplementary feeding in grazing dairy cows? John Roche and a University of Auckland - Waipapa Taumata Rau, Teagasc Dairy, DairyNZ, and University of Tasmania team tackle nutrition considerations for pasture-based systems in the 👉 https://doi.org/10.3168/jdsc.2025-0992

Highlights
✅Well-managed pasture meets the requirements of moderate-yielding dairy cows.
✅Metabolizable energy intake is the primary nutritional limit to milk production.
✅Supplementation increases intake but reduces pasture intake and utilization via substitution.
✅Protein and amino acids rarely limit milk unless supplements exceed ~30% of diet DM.
✅Individualized concentrate feeding has not reliably improved herd milk production.

Curious about what a career in looks like from both academia and industry? Tune into the latest , with Pablo Ross, DVM, PhD, Chief Scientific Officer at STgenetics. He explains how he came to transition from research and teaching to his industry role, sharing how dairy genetics research is dramatically shortening generational intervals and improving feed efficiency, and proving that industry is a powerhouse for serious, impactful science.

How can we optimize forage plant selection for pasture-based dairy systems? In a new article a School of Agriculture and Environment - Massey University team led by Daniel J. Donaghy proposes a pragmatic, science-based framework that prioritizes functional trait diversity over species richness 👉https://doi.org/10.3168/jdsc.2026-1028

Highlights
✅ Diverse pastures can enhance system productivity and resilience.
✅ Benefits arise from strategic plant selection rather than increasing plant number.
✅ Farmers can optimize their pasture systems by using our framework.
✅ We propose an approach to enhance use of existing pasture selection tools.
