A progeny test compares the performance of sires through their offspring. We do this by using sires over many cows and ewes, across many farms, then measure the performance of their calves and lambs. By using key linking sires across a range of farms and environments, we can benchmark bulls and rams for any farm in New Zealand.
B+LNZ Genetics oversees three different progeny tests. The Sheep Progeny Test is a long-standing and critical component of New Zealand’s sheep genetics system. The Beef Progeny Test was launched in 2014 and is generating valuable commercial insights for farmers, while the Dairy-Beef Progeny Test is the most recent project. It is looking at how more beef genetics can be used in the dairy industry, to benefit both the dairy and beef farmers.
