The transition period - from three weeks before to three weeks after calving - is the highest-risk phase of the dairy cow's production cycle for health and welfare.
The transition period concentrates multiple health and welfare challenges in a brief, critical window. Cows navigating this period successfully requires precise nutritional management, reduced social stress, and close health monitoring. Given the high prevalence of transition diseases in many herds, this phase represents one of the most significant welfare challenges in commercial dairy production.
