|Title:||Genetic Parameters for Body-Weight Traits of a Native Poultry Breed in Thailand||Contributor(s):||Tongsiri, Tookky (author); Jeyaruban, M Gilbert (author); Hermesch, Susanne (author) ; Van Der Werf, Julius H (author) ; Li, Li (author); Chormai, T (author)||Publication Date:||2017||Open Access:||Yes||Handle Link:||https://hdl.handle.net/1959.11/23435||Open Access Link:||http://agbu.une.edu.au/AAABG%202017/56Tongsiri22245.pdf||Abstract:||The heritabilities and genetic correlations for body-weights measured at day-old (BW1D), and at 4 (BW4), 8 (BW8), 12 (BW12), 16 (BW16), 20 (BW20) and 24 (BW24) weeks of age, and also at first egg (BWFE) of Thai native chickens (Lueng Hang Kao Kabinburi, LHKK) were estimated using Restricted Maximum Likelihood (REML) procedures. Data were from the Kabinburi Livestock Research and Breeding Center, Thailand and the records contained five generations of performance records on 11,588 birds born from 2003 to 2007. Estimates of heritabilities for additive genetic effects of body-weight traits ranged from 0.10 to 0.51. Heritabilities for maternal genetic effects ranged from 0.04 to 0.25, except for BWFE, which had no significant maternal genetic effects. Significant maternal permanent environmental effects were observed for all traits, except for BW24 and BWFE. Estimates of additive genetic correlations between the body-weight traits ranged from 0.25 to 0.99. Estimated heritabilities and genetic correlations between body-weight traits suggest that the growth performance of LHKK chickens can be improved by selection on one or more juvenile weight traits.||Publication Type:||Conference Publication||Conference Name:||22nd Conference of the Association for the Advancement of Animal Breeding and Genetics, Townsville, Australia, 2nd - 5th July, 2017||Conference Details:||22nd Conference of the Association for the Advancement of Animal Breeding and Genetics, Townsville, Australia, 2nd - 5th July, 2017||Source of Publication:||Proceedings of the Twenty-second (22nd) Conference of the Association for the Advancement of Animal Breeding and Genetics, v.22, p. 245-248||Publisher:||AAABG: Association for the Advancement of Animal Breeding and Genetics||Place of Publication:||Fitzroy, Australia||ISSN:||1328-3227||Field of Research (FOR):||070201 Animal Breeding||Socio-Economic Outcome Codes:||830309 Poultry||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Other Links:||http://www.aaabg.org/aaabghome/
