Title: | Where to from Brahmans in the northern Australian herd?: Maintaining the economic benefit of earlier infusions of 'Bos indicus' | Contributor(s): | Burrow, Heather Mary (author) ; Griffith, G R (author); Barwick, Stephen (author); Holmes, W E (author) | Publication Date: | 2003 | Handle Link: | https://hdl.handle.net/1959.11/4384 | Abstract: | Economic values derived from a terminal crossbreeding system based on Brahman cows and a tropically adapted composite herd targeted to meet specifications of the grass-finished Japanese market were compared to a straightbred Brahman herd. The model represented a typical individual central Queensland integrated breeding/finishing enterprise or a northern Australian vertically integrated enterprise with separate breeding and finishing properties. Due mainly to a reduced age of turnoff of Crossbred and Composite sale animals and an improved weaning rate in the Composite herd, Crossbred and Composite herds returned a gross margin of $7 and $24 per Adult Equivalent (AE) respectively above that of the Brahman herd. The benefits of changing 25% of the existing 85% of Brahmans in the northern Australian herd to either Crossbreds or Composites over a 10-year period were also examined, using either no premium or a 5c per kg premium for carcass quality in Crossbred and Composite sale animals. With no premium, annual benefits were $16m and $61m for Crossbreds and Composites in 2013. The cumulative Present Value (PV) of this shift over the 10-year period was $88m and $342m respectively, discounted at 7%. When a 5c per kg premium for carcass quality was included, differences in annual benefits rose to $30m and $75m and cumulative PVs to $168m and $421m for Crossbreds and Composites respectively. | Publication Type: | Conference Publication | Conference Details: | AAABG 2003: 15th Conference of the Association for the Advancement of Animal Breeding and Genetics, Melbourne, Australia, 7-11 July, 2003 | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.15, p. 294-297 | 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://www.aaabg.org/livestocklibrary/2003/294-297.pdf |
