The transition period around calving is the highest-risk welfare phase of a dairy cow's productive life.
Transition period welfare in dairy cows requires proactive management because the metabolic demands of calving and early lactation exceed what many cows can handle without support. Failure of transition management leads to a cascade of painful conditions including ketosis, lameness, and mastitis. The welfare of a dairy cow's entire lactation often depends on how well her transition period is managed.
