Repeated observations have the advantage of allowing for adjustment of effects associated with each competition such as rider experience, judge and competing horses, but also demands more computer capacity than single\u2010trait records, which could prohibit multiple\u2010trait evaluations. The aim of the study was to compare\n CPU<\/jats:styled-content>\n times, estimated breeding values (\n EBV<\/jats:styled-content>\n s), reliabilities and model prediction abilities when modelling repeated competition ranking points (run A), mean ranking points (runs B and C), mean ranking points precorrected for effects associated with each competition (run D) and accumulated lifetime points (run E) for\n D<\/jats:styled-content>\n anish\n W<\/jats:styled-content>\n armblood horses.\n CPU<\/jats:styled-content>\n times for run A were 632\u2013776 times (show jumping) and 59\u201396 times (dressage) as high as for runs B\u2013E.\n EBV<\/jats:styled-content>\n s of run D were perfectly correlated (1.00) with those of run A. Reliabilities were highest in runs E and A. Best model prediction ability and least bias were found in run C (dressage) and run E (show jumping), but the best choice in each discipline was not preferable for the other. Run D was the second best in both disciplines (D), and is expected to increase in performance over time as omission of a relatively large amount of historic data becomes less important.\n <\/jats:p>","DOI":"10.1111\/jbg.12190","type":"journal-article","created":{"date-parts":[[2015,11,18]],"date-time":"2015-11-18T22:13:16Z","timestamp":1447884796000},"page":"291-302","source":"Crossref","is-referenced-by-count":4,"title":["Modelling repeated competition records in genetic evaluations of\n D<\/scp>\n anish sport horses"],"prefix":"10.1111","volume":"133","author":[{"given":"L.","family":"J\u00f6nsson","sequence":"first","affiliation":[{"name":"Department of Clinical Veterinary and Animal Sciences Faculty of Health and Medical Sciences University of Copenhagen Copenhagen Denmark"},{"name":"Danish Warmblood Association Maarslet Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Madsen","sequence":"additional","affiliation":[{"name":"Department of Molecular Biology and Genetics Center for Quantitative Genetics and Genomics Aarhus University Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Mark","sequence":"additional","affiliation":[{"name":"Department of Clinical Veterinary and Animal Sciences Faculty of Health and Medical Sciences University of Copenhagen Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,11,18]]},"reference":[{"key":"e_1_2_6_2_1","unstructured":"BoellingD.(2011)Description of competition index (in Danish).
