The transition period is the most critical stage of the dairy cow’s production cycle and, despite decades of research, nutrition during this period remains an active frontier, with new insights into nutrient metabolism and immune regulation. Transition cow management is consistently cited by dairy producers, nutritionists, and veterinarians as a top priority because it directly drives herd profitability and long-term sustainability. Nutritional strategies that improve metabolism reduce metabolic disease, support fertility, and increase efficiency. This symposium focused on dietary strategies to optimize transition cow performance.
