Title: | Genetic variation and heritability of ostrich weight traits | Contributor(s): | Engelbrecht, A (author); Cloete, S W P (author); Bunter, Kim L (author); van Wyk, J B (author) | Publication Date: | 2011 | Handle Link: | https://hdl.handle.net/1959.11/9863 | Abstract: | Estimates of genetic parameters for ostrich weight traits (recorded from 1 to 12 months of age) were obtained with multiple-trait animal models. Heritability estimates ranged from 0.06 for 1-month weight to 0.36 for 11-month weight, generally increasing with age. Concurrent estimates for hen permanent environment effects were low, without a specific trend. Genetic correlations among weight traits were positive, although correlations between weight at 1-month of age and later weight traits were generally not significantly different from zero. Moderate to high heritability estimates and high genetic correlations amongst later weights indicate that selection for weight at ages higher than 7 months of age would be effective in improving weight at slaughter. | Publication Type: | Conference Publication | Conference Details: | AAABG 2011: 19th Conference of the Association for the Advancement of Animal Breeding and Genetics, Perth, Australia, 19th - 21st July, 2011 | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.19, p. 183-186 | 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: | 830399 Livestock Raising not elsewhere classified | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication | Publisher/associated links: | http://trove.nla.gov.au/work/162660639 http://www.aaabg.org/aaabg19/ |
