Genetic benchmarking of carcase traits in Terminal sheep flocks possible with genomic testing

Abstract

<p>The Flock Profile test has been successfully used to genetically benchmark Merino flocks (Swan <i>et al.</i> 2018). This is a crucial tool for those breeders without any knowledge of their current genetic benchmark. While the average Australian Sheep Breeding Value (ASBV) of rams purchased is often the most accurate metric, this is not always available, especially if the flock has not previously used ASBVs. At present, Flock Profile tests have only been validated in purebred Merino flocks. However, the rate of genetic gain would likely be enhanced across the industry if this test were available for other breeds and in particular for commercial crossbred flocks. This study aimed to examine the predictive ability of the Flock Profile test in terminal sheep breeds as estimated from the terminal LAMBPLAN analysis.</p>
