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 +17), moderate gains in Ywt (-2.5 to +2.4) and significantly improving Ywec (-14 to -27), whilst maintaining our outstanding Yfd since 2010. During this time Cressbrook’s FP+ average index rank (160) 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
ASBV Drop Average Genetic Gain 2010 – 2020
