Calliper and ultrasonographic measurements of testicular dimensions (length, width and height) of both testes were taken on five adult collared peccaries. The testicular volume was calculated by <jats:styled-content style=\"fixed-case\">L<\/jats:styled-content>ambert's empiric formula: length (<jats:styled-content style=\"fixed-case\">L<\/jats:styled-content>)\u00a0\u00d7\u00a0width (<jats:styled-content style=\"fixed-case\">W<\/jats:styled-content>)\u00a0\u00d7\u00a0height (<jats:styled-content style=\"fixed-case\">H<\/jats:styled-content>)\u00a0\u00d7\u00a00.71, the formula of an ellipsoid <jats:styled-content style=\"fixed-case\">L<\/jats:styled-content>\u00a0\u00d7\u00a0<jats:styled-content style=\"fixed-case\">W<\/jats:styled-content>\u00a0\u00d7\u00a0<jats:styled-content style=\"fixed-case\">H<\/jats:styled-content>\u00a0\u00d7\u00a00.52, and <jats:styled-content style=\"fixed-case\">H<\/jats:styled-content>ansen's formula: <jats:styled-content style=\"fixed-case\">L<\/jats:styled-content>\u00a0\u00d7\u00a0<jats:styled-content style=\"fixed-case\">W<\/jats:styled-content><jats:sup>2<\/jats:sup>\u00a0\u00d7\u00a00.52. The calculated volumes were then compared with the actual ones, which were estimated by water displacement. The mean of true testicular volume was 22.65\u00a0\u00b1\u00a01.52\u00a0ml. Lambert's formula estimated testicular volume more accurately when ultrasound measurements were taken. However, when the calliper was the methodology used, the results were closest to the true volume, especially when <jats:styled-content style=\"fixed-case\">E<\/jats:styled-content>llipsoid formula and <jats:styled-content style=\"fixed-case\">H<\/jats:styled-content>ansen's formula were applied, and underestimated the true volumes by 1.53\u00a0\u00b1\u00a01.75\u00a0ml and 1.53\u00a0\u00b1\u00a01.65\u00a0ml, respectively. This specific application of technologies in wild animals has the potential to revolutionize the selection process for the collared peccary entering artificial insemination or natural breeding programmes.<\/jats:p>","DOI":"10.1111\/ahe.12171","type":"journal-article","created":{"date-parts":[[2015,1,27]],"date-time":"2015-01-27T15:46:14Z","timestamp":1422373574000},"page":"60-66","source":"Crossref","is-referenced-by-count":8,"title":["Use of Non\u2010invasive Methods for Evaluating the Testicular Biometry in Collared Peccaries (<i>Pecari tajacu<\/i> Linnaeus, 1758)"],"prefix":"10.1111","volume":"45","author":[{"given":"G.
