The B+LNZ Genetics Beef Progeny Test compares bulls under New Zealand commercial farming conditions. The test involves about 2200 cows and heifers each year, on five large properties across New Zealand. A mix of both internationally-sourced and New Zealand semen is used. Steers and cull heifers are assessed on their carcase traits, while replacement heifers are tracked for their maternal characteristics.

Key messages for commercial farmers

  1. EBVs deliver on what they predict, so use them to make more money.If you don’t understand them, talk to someone who does and ask about them.
  2. Aim for a cow condition score of 6-7 at mating to maximise pregancy rates.
  3. AI is not as onerous as you might think, especially for the genetic gain you can make.
