The first weeks of life are the most welfare-critical period for calves, with colostrum management, social housing, and pain management determining long-term outcomes.
Early life welfare investments in calves have disproportionately large effects on lifelong outcomes. Colostrum management determines disease resistance and survival. Social housing from the first weeks enables normal behavioural development — pair-housed calves show better learning, reduced fear, and improved social cognition compared to singly-housed calves. Pain management during necessary procedures reduces both acute suffering and adverse long-term behavioural effects. These early investments create lasting welfare dividends throughout the animal's life.
