The transition period is the highest-risk window in a dairy cow's life, with far-reaching consequences for health, productivity, and farm profitability. In this comprehensive episode, we speak with Donald Lawson, head of the ruminant team at Premier Nutrition, who shares invaluable insights from his extensive experience managing transition cow nutrition.
Donald reveals how approximately 80% of health problems in dairy cows originate during the six-week window around calving, and how getting transition management right can save farms an average of 6 pence per litre. Drawing from Premier Nutrition's Transition Management System data covering 200,000 cows, he breaks down the critical factors that determine transition success – from optimal body condition scores to feed space requirements and straw processing techniques.
We explore a wide range of transition approaches, including partial and full DCAD diets, calcium binders, and the highly effective "Goldilocks" diet focusing on optimal forage NDF levels. Donald explains the science behind these strategies while providing practical, farm-level implementation advice that works across different systems.
Perhaps most fascinating is the emerging research showing how transition management affects not just the cow but also her calf, with proper calcium levels at day four post-calving linked to improved calf health outcomes. We also discuss the latest findings on amino acids, choline, and other nutritional interventions that provide returns throughout the entire lactation cycle.
Whether you're struggling with milk fever, ketosis, or simply want to optimize your transition program, this episode offers both technical depth and practical wisdom. Donald's parting advice? "Don't go looking for savings in your dry cow diet. It's the one place you should spend the money."
