| Abstract |
<p>This study aimed to detect genomic regions associated with scrotal circumference in Australian
Brahman, Hereford, and Wagyu beef cattle breeds. The presence of selection signatures was based
on the FST test, using data on the genotype and BREEDPLAN estimated breeding values for SC of
100,990 animals. Signals of selection for scrotal circumference were identified in genomic regions
on several chromosomes, especially chromosome 14 in Brahman with most candidate genes under
selection associated with male fertility or growth. The findings of this study may be applicable to
breeding programs using more informative markers and assigning higher weights to them to increase
the accuracy of genomic predictions and improve the reproductive performance of beef cattle.</p>
