Results to date are as follows: • 891 yearling heifers mated in total: 639 dairy-beef heifers (bought-in) 252 beef heifers (home-bred). • 53% of OBH heifers scanned in-calf to a one-shot fixed time AI. • 85% or 761 heifers in-calf following oneshot AI followed by one and a half cycles of natural bull mating: 91% of dairy-beef heifers in-calf (earlier born and first-cross) 71% of beef heifers in-calf (mated one month earlier than normal for OBH). Another important twist with the Rangitaiki OBH programme is that the most efficient calf producing dairy-beef heifers will be retained as replacements for the beef herd. To achieve that outcome, the heifers in-calf to fixed-time-AI have been identified thus reducing the need to record birth date. A total of 200 replacements are required and so the heaviest 250 calves will be rematched with their mothers postweaning. Once rematched, those heifers without calves will be drafted-off for
