Sheep and beef breeders have a higher cost:benefit ratio for GS compared to dairy. Therefore, strategies for genotyping selection candidates should be explored to maximize the economic benefit of GS. The aim of the paper was to investigate, via simulation, the additional genetic gain achieved by selecting proportions of male selection candidates to be genotyped via truncation selection. A two\u2010trait selection index was used that contained an easy and early\u2010in\u2010life measurement (such as post\u2010weaning weight) as well as a hard\u2010to\u2010measure trait (such as intra\u2010muscular fat). We also evaluated the optimal proportion of female selection candidates to be genotyped in breeding programmes using natural mating and\/or artificial insemination (NatAI), multiple ovulation and embryo transfer (MOET) or juvenile in vitro fertilization and embryo transfer (JIVET). The final aim of the project was to investigate the total dollars spent to increase the genetic merit by one genetic standard deviation (<jats:italic>SD<\/jats:italic>) using GS and\/or reproductive technologies. For NatAI and MOET breeding programmes, females were selected to have progeny by 2\u00a0years of age, while 1\u2010month\u2010old females were required for JIVET. Genomic testing the top 20% of male selection candidates achieved 80% of the maximum benefit from GS when selection of male candidates prior to genomic testing had an accuracy of 0.36, while 54% needed to be tested to get the same benefit when the prior selection accuracy was 0.11. To achieve 80% of the maximum benefit in female, selection required 66%, 47% and 56% of female selection candidates to be genotyped in NatAI, MOET and JIVET breeding programmes, respectively. While JIVET and MOET breeding programmes achieved the highest annual genetic gain, genotyping male selection candidates provides the most economical way to increase rates of genetic gain facilitated by genomic testing.<\/jats:p>","DOI":"10.1111\/jbg.12381","type":"journal-article","created":{"date-parts":[[2019,1,29]],"date-time":"2019-01-29T03:44:04Z","timestamp":1548733444000},"page":"91-101","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Genotyping strategies of selection candidates in livestock breeding programmes"],"prefix":"10.1111","volume":"136","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0345-0248","authenticated-orcid":false,"given":"Tom","family":"Granleese","sequence":"first","affiliation":[{"name":"Sheep Cooperative Research Centre Armidale New South Wales Australia"},{"name":"School of Environmental &amp; Rural Science University of New England Armidale New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel A.","family":"Clark","sequence":"additional","affiliation":[{"name":"Sheep Cooperative Research Centre Armidale New South Wales Australia"},{"name":"School of Environmental &amp; Rural Science University of New England Armidale New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julius H.
