       Wairakei Renown: 2018 UPDATE


       FOLLOWING  THE  DEMONSTRATION of the effectiveness of
       EBVs for predicting performance in the dairy beef system, the
       project at Renown aims to identify outstanding bulls for use
       in dairy beef that perform strongly at calving, rearing, finishing
       and carcass stages of the supply chain. Just over 800 calves
       were tagged and weighed on-farm in spring 2018, and DNA
       parentage is currently pending to allow us to determine the
       performance of individual sires. Calves are now weaned and
       have moved to Pamu’s Orakonui property within the Wairakei
       complex for finishing. Calving was successful, with around 1%
       of calves assisted at birth.
          The second round of mating is complete, with pregnancy
       testing to follow in autumn 2019. We look forward to following the
       performance of the many promising bulls entered in this test.
