Lower Wrinkle and Dag Reduce the Risk of Breech Strike

This page looks at the possibly ways to reduce the risks of a breech strike - a lot of it seems to do with breeding.


What is the Problem?

The problem to be resolved revolves around that as the wrinkle and dag largely cause a breech strike, wrinkle and dag should be lowered to further reduce the risks of a breech strike to animals.

Breech Wrinkle and Dags are the key breech strike risk traits.  As there is a general unfavourable relationship between fleece weight and wrinkle, it is important to pursue sires that are good for both (as well as fertility, growth, structure and the other resilience/welfare traits, in a balanced approach). There are sires and studs that bend this relationship; these “curve benders” are relatively higher in fleece weight and lower in wrinkle.

However, the level of wrinkle on Australian Sheep Breeding Value or (ASBV) can ascend if the sheep is located in a place where there are low protein and low energy.

What did the research involve?

A research funded by Animal Welfare Institute (AWI) operated at Armidale NSW (CSIRO) and Mt Barker WA (DAFWA) found that every diminution of 0.1 in breech trait scores results to the descending of lifetime breech strike risks for either mulesed and un-mulesed animals.

What were the key findings?

Knowing how genetics and environment interact to create an animal’s phenotype on a commercial property is an important step in knowing what targets to set, to maximise lifetime productivity and welfare.

Final Comment

It is important to be informed how the genetics and environment interact with each other in order to formulate an animal’s characteristics
