New research has just emerged revealing that omega-3 fatty acids are essential for enhancing cow longevity and survival rates. This groundbreaking study, conducted by Dairy UP researcher David Sheedy, will be presented at the 2025 Dairy Research Foundation Symposium in Wollongong on November 26 and 27.
The findings indicate that increasing omega-3 levels in dairy cows could significantly improve reproductive health and overall wellbeing, potentially transforming practices in the dairy industry. “With each additional lactation, the likelihood of reproductive and health problems increases,” Sheedy stated. “Farmers often sell cows at younger ages than may be optimal to avoid these issues.”
The study, which analyzed 2,000 blood samples from 29 Australian dairy herds, discovered that blood levels of omega-3 fats significantly decline with age. “If we can boost omega-3 levels through supplementation, the potential gains for herd longevity are substantial,” Sheedy emphasized.
The implications of this research are profound. By reducing metabolic challenges that arise with age, producers could operate more flexible, resilient, and profitable herds. The Dairy UP team is now investigating omega-3 supplementation strategies, focusing on marine-sourced products rich in these fatty acids, to evaluate their long-term effects on cattle health, reproduction, and survival.
As this research unfolds, it underscores a critical opportunity for dairy farmers to enhance the vitality of their herds. The Dairy Research Foundation Symposium promises to be a pivotal event for sharing these innovative findings. For further details, visit drfsymposium.com.au and www.dairyup.com.au.
