The current study assesses growth, hormonal and seminal traits measured in Brahman and tropical Composite bulls (n=2212) from weaning through to 2 years. Heritability of scrotal size (39 to 75%), prepubertal serum concentration of inhibin (40 to 71%) and semen quality traits (19 to 27%) indicated potential to genetically improve these traits in both Brahman and tropical Composite populations. Genetic correlations between male traits varied (-46 to 78%), some suggesting antagonism between traits while others indicated that some traits measured in bulls early in life could potentially be indicators of post-pubertal semen quality. | Publication Type: | Conference Publication | Conference Details: | AAABG 2009: 18th Conference of the Association for the Advancement of Animal Breeding and Genetics, Barossa Valley, Australia, 27th September - 1st October, 2009 | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.18, p. 121-124 | Publisher: | Association for the Advancement of Animal Breeding and Genetics (AAABG) | Place of Publication: | Armidale, Australia | ISSN: | 1328-3227 | Fields of Research (FoR) 2008: | 070201 Animal Breeding | Socio-Economic Objective (SEO) 2008: | 830301 Beef Cattle | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication | Publisher/associated links: | http://aaabg.org/aaabg18/ http://trove.nla.gov.au/work/36420775 http://www.aaabg.org/proceedings18/files/corbet121.pdf |
