Abstract

Regression coefficients were estimated of sensory and objective eating quality (EQ) traits on sire
Australian Sheep Breeding Values (ASBVs) for a range of Merino production traits to identify if
genetic relationships were likely to exist between these traits. The sire ASBVs were not associated
with either overall liking scores of loin, knuckle and topside cuts, or intramuscular fat and shear
force of the loin. This preliminary study has shown that it is likely that selection on sire ASBVs to
improve Merino production traits would yield negligible responses in EQ traits.

Other	The Association for the Advancement of Animal Breeding and Genetics is a professional organisation based in Australia and New Zealand for livestock scientists, breeders, educators, students and industry service providers. The major activity conducted by AAABG to achieve its objectives is an international conference held at approximately two year intervals. Our principal objectives are to: (i) promote scientific research on the genetics of animals, (ii) foster the application of genetics in animal production and (iii) develop communication among all those interested in the application of genetics to animal production, particularly breeders and their organisations, consultants, extension workers, educators and geneticists.
