Abstract: Genomic selection offers the opportunity to improve female fertility in the Northern Australian beef herd. However, genomic predictions for a number of female fertility traits - derived solely from the small number of female fertility records collected thus far - are only of modest accuracy. In this study measures of Brahman male reproduction were used jointly with the female records, increasing the accuracy of genomic predictions for Brahman female fertility. Scrotal circumference measured at 18 months was found to be the most useful to increase accuracies of cow GEBVs for a range of traits upto 22%.
