Our Progress

It can be seen from the table of Australian Sheep Breeding Values that Cressbrook Merinos have made significant genetic improvements in Ycfw (-8.1 to +11), moderate gains in Ywt (-2.5 to +0.5) and significantly improving Ywec (-14 to -30), whilst maintaining our outstanding Yfd since 2010.  During this time Cressbrook’s FP+ average index rank (149) has tracked far ahead of the ultra/superfine industry average (133)

These genetic trends are drawn from a drop of 600+ stud progeny each year.  Bear in mind that the 100 strong sale team that is offered each year is drawn from a drop of 300+ ram lambs, hence sale team average ASBV’s are significantly higher.

Each year our sale team is amongst the best in the industry for low YFD and high YCFW – the two most important traits that drive fleece value
