A progeny test compares the performance of sires through their offspring. This is done by using sires over many cows and ewes, across many farms, then measuring 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 two 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, while a Dairy-Beef Progeny Test was launched the following year. The two tests have since been combined. 

Sheep Progeny Test There are now seven properties involved in the Sheep Progeny Test. Take a closer look at each operation and specific projects underway. View Beef Progeny Test The Beef Progeny Test compares a mix of New Zealand and international bulls under large-scale commercial farming conditions. The key finding? EBVs work. View Dairy-Beef Progeny Test This test explores how to promote the use of beef genetics in the dairy industry – to benefit both the dairy and beef sectors. View
