The integration of heifers with the main dairy herd during the post calving period can lead to reduced welfare and production performance. The aim of this study was to assess whether any benefits to welfare or productivity are shown when heifers are introduced to groups of mature cows as pairs rather than individuals. In addition, the benefit of allowing heifers a 1-week recovery period after calving before being introduced to these groups was also assessed.
