|Title:||Optimal development of the Australian sheep genetic resources||Contributor(s):||Van Der Werf, Julius Herman (author)||Publication Date:||2005||Handle Link:||https://hdl.handle.net/1959.11/4501||Abstract:||The Australian sheep industry is at a crossroads where technical opportunities allow rapid genetic change, and market developments tend to favour a shift in profitability from wool to meat production. A key question is how the existing genetic resources should be developed optimally to maximize future profitability across the Australian sheep industry. Breeding objectives need to be developed jointly for wool and terminal sire breeds, taking into account the joint use of these breeds in a crossbreeding system. A simple model was trialed, optimizing profit per unit of feed, suggesting that a crossbreeding system remains in place with specialized wool and meat breeds. Optimal development involves increased body size for meat breeds but increased wool production and quality and decreased body size for wool breeds that also serve as dams of prime lambs. Both wool and meat breeds should increase reproductive rate.||Publication Type:||Conference Publication||Conference Name:||16th Conference of the Association for the Advancement of Animal Breeding and Genetics, Noosa Lakes, Queensland, Australia, 25th September - 28th September, 2005||Conference Details:||16th Conference of the Association for the Advancement of Animal Breeding and Genetics, Noosa Lakes, Queensland, Australia, 25th September - 28th September, 2005||Source of Publication:||Application of new genetic technologies to animal breeding: Proceedings of the 16th Conference of the Association for the Advancement of Animal Breeding and Genetics, p. 176-179||Publisher:||CSIRO Publishing||Place of Publication:||Collingwood, Australia||ISSN:||1328-3227||Field of Research (FOR):||070201 Animal Breeding||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Other Links:||http://www.aaabg.org/livestocklibrary/2005/176van_der_werf.pdf
