The fertility outcome (farrowing rate \u2013 <jats:styled-content style=\"fixed-case\">FR<\/jats:styled-content> and total piglets born \u2013 <jats:styled-content style=\"fixed-case\">TB<\/jats:styled-content>) of 14 boars was obtained from a field trial conducted during 10\u00a0week of breeding period on a commercial farm using multiparous sows (n\u00a0=\u00a0948) through single\u2010sire mating with 2\u00a0\u00d7\u00a010<jats:sup>9<\/jats:sup> motile sperm cells per <jats:styled-content style=\"fixed-case\">artificial insemination (AI)<\/jats:styled-content> dose. Sperm motion parameters, evaluated with computer\u2010assisted semen analysis system in raw and stored semen at 17\u00b0C for 240\u00a0h, in addition to morphological sperm defects, measured on the collection day, were included in the analysis to determine which semen traits were important to discriminate the fertility potential of ejaculates from these boars. The data underwent multivariate cluster, canonical and discriminant analyses. Four clusters of boars were formed based on fertility outcome. One boar, with the lowest <jats:styled-content style=\"fixed-case\">FR<\/jats:styled-content> and <jats:styled-content style=\"fixed-case\">TB<\/jats:styled-content> values (89.7% and 11.98), and two boars, with the highest <jats:styled-content style=\"fixed-case\">FR<\/jats:styled-content> and <jats:styled-content style=\"fixed-case\">TB<\/jats:styled-content> values (97.8% and 14.16), were placed in different clusters. The other boars were separated in two distinct clusters (four and seven boars), including boars with intermediate <jats:styled-content style=\"fixed-case\">TB<\/jats:styled-content> (12.64 and 13.22) but divergent values for <jats:styled-content style=\"fixed-case\">FR<\/jats:styled-content> (95.9% vs 91.8%). Semen traits with higher discriminatory power included total motility, progressive motility, amplitude of lateral head displacement and cytoplasmatic droplets. Through multivariate discriminant analysis, more than 80% of the 140 ejaculates were correctly classified into their own group, showing that this analysis may be an efficient statistical tool to improve the discrimination of potential fertility of boars. Nevertheless, the validation of the relationship between fertility and semen traits using this statistical approach needs to be performed on a larger number of farms and with a greater number of boars.<\/jats:p>","DOI":"10.1111\/rda.12155","type":"journal-article","created":{"date-parts":[[2013,3,15]],"date-time":"2013-03-15T23:07:50Z","timestamp":1363388870000},"page":"747-754","source":"Crossref","is-referenced-by-count":18,"title":["Multivariate Analyses for Determining the Association of Field Porcine Fertility With Sperm Motion Traits Analysed by Computer\u2010Assisted Semen Analysis and With Sperm Morphology"],"prefix":"10.1111","volume":"48","author":[{"given":"ABHP","family":"Kummer","sequence":"first","affiliation":[{"name":"Setor de Su\u00ednos Faculdade de Medicina Veterin\u00e1ria Universidade Federal do Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"TS","family":"Gaggini","sequence":"additional","affiliation":[{"name":"Setor de Su\u00ednos Faculdade de Medicina Veterin\u00e1ria Universidade Federal do Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ML","family":"Bernardi","sequence":"additional","affiliation":[{"name":"Departamento de Zootecnia Faculdade de Agronomia Universidade Federal do Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"McManus","sequence":"additional","affiliation":[{"name":"Departamento de Zootecnia Faculdade de Agronomia Universidade Federal do Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"EM","family":"Gon\u00e7ales","sequence":"additional","affiliation":[{"name":"Setor de Su\u00ednos Faculdade de Medicina Veterin\u00e1ria Universidade Federal do Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I","family":"Wentz","sequence":"additional","affiliation":[{"name":"Setor de Su\u00ednos Faculdade de Medicina Veterin\u00e1ria Universidade Federal do Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"FP","family":"Bortolozzo","sequence":"additional","affiliation":[{"name":"Setor de Su\u00ednos Faculdade de Medicina Veterin\u00e1ria Universidade Federal do Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,3,15]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1095\/biolreprod60.1.32"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0531.2005.00670.x"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.anireprosci.2011.10.005"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0531.2011.01861.x"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.2527\/jas.2011-4311"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2011.05.040"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2011.11.016"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2008.07.014"},{"key":"e_1_2_5_10_1","first-page":"61","article-title":"Artificial insemination in pigs, research and developments in The Netherlands, a review","volume":"37","author":"Feitsma H","year":"2009","journal-title":"Acta Sci Vet"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0531.2011.01867.x"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2008.07.015"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2004.09.023"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4320(98)00144-4"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0531.2004.00513.x"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2008.07.007"},{"key":"e_1_2_5_17_1","first-page":"664","article-title":"The collection of boar semen","volume":"71","author":"Hancock JL","year":"1959","journal-title":"Vet Rec"},{"key":"e_1_2_5_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1939-4640.2001.tb02159.x"},{"key":"e_1_2_5_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1939-4640.1997.tb01925.x"},{"key":"e_1_2_5_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4320(00)00157-3"},{"key":"e_1_2_5_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0531.1999.tb01388.x"},{"key":"e_1_2_5_22_1","unstructured":"LovercampK SutovskyP 2008:Cytoplasmic droplets: the most frequently observed abnormality.
