Abstract: | We predicted genetic gains for reducing breech flystrike incidence (FSI) based on selection using modified MERINOSELECT indexes. Predicted genetic reductions in FSI after 10 years of selection were larger when the heritability of the trait was moderate (as in a summer rainfall environment) than when a low heritability was assumed (as in a winter rainfall environment). The relative gains between flystrike incidence and fleece weight, fibre diameter and reproductive rate and their implications for Merino breeding programs are discussed. | Publication Type: | Conference Publication | Conference Details: | AAABG 2019: 23rd Conference of the Association for the Advancement of Animal Breeding and Genetics, Armidale, Australia, 27 October-1 November | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.23, p. 528-531 | 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 830311 Sheep - Wool |
