Title: | Genetic Parameters for Eating Quality Traits of Australian Lamb | Contributor(s): | Mortimer, S I (author); Swan, Andrew (author) ; Pannier, L (author); Ball, Alexander (author); Jacob, R H (author); Van Der Werf, Julius H (author) ; Pethick, David W (author) | Publication Date: | 2015 | Open Access: | Yes | Handle Link: | https://hdl.handle.net/1959.11/19027 | Open Access Link: | http://www.aaabg.org/aaabghome/AAABG21papers/Mortimer21209.pdf | Abstract: | Genetic parameters were estimated for 5 sensory (overall liking, tenderness, juiciness, flavour and liking of odour) and 2 objective eating quality (EQ) traits (intramuscular fat, IMF, and shear force, SF), measured on loin and topside meat cuts (except IMF) produced by progeny from the Information Nucleus of the CRC for Sheep Industry Innovation. Heritabilities for sensory traits were low to moderate for loin and moderate to high for topside cuts. Loin IMF was highly heritable while SF was moderately heritable in both cuts. Genetic correlations among the sensory EQ traits were all positive and high (0.72-1.00). Genetic correlations between loin IMF and sensory traits were moderately positive and lowly positive for loin and topside respectively. SF had stronger, negative correlations with sensory EQ traits in the topside than in the loin. Overall liking may be improved more so through selection on IMF in the loin and SF in the topside. | Publication Type: | Conference Publication | Conference Details: | AAABG 2015: 21st Conference of the Association for the Advancement of Animal Breeding and Genetics, Lorne, Australia, 28th - 30th September, 2015 | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.21, p. 209-212 | 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 | Fields of Research (FoR) 2020: | 300305 Animal reproduction and breeding | Socio-Economic Objective (SEO) 2008: | 830310 Sheep - Meat | Socio-Economic Objective (SEO) 2020: | 100412 Sheep for meat | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication | Publisher/associated links: | http://www.aaabg.org/aaabghome/proceedings21.php |
