Twenty\u2010six adult boars from four different racial groups were used, 10 from the Piau breed (group 1), four from the commercial and finishing group (group 2), six Pietrain breed (group 3) and six from the Duroc breed (group 4). All animals were evaluated for breeding soundness evaluation and the ultrasound examination of the testicles. The groups of animals that were evaluated showed no difference in the main semen parameters that were evaluated, except for the sperm volume, concentration of the ejaculated sperm and the supravital staining; the lowest figures were for the animals from the Piau breed (group 1). In relation to the testicular biometrics, Duroc animals (group 4) had a greater scrotal width compared to the other groups. But when we assessed the intensity of pixels of the testicles, there was a difference between groups. The groups 2 (finishing animals), 3 (Pietrain) and 4 had no difference between themselves. Group 3 had greater pixel intensity in relation to group 1. Of the 26 animals studied, five showed an abnormality during ultrasound evaluation, like hydrocele, hyperechoic mass in the testicular parenchyma, cyst in the head of the epididymis and the presence of fluid in the head and tail of the epididymis. The various animal groups studied did not differ in the principal reproductive parameters evaluated, showing that despite the great variability of reproductive traits between breeds and within the same breed, the breeding soundness evaluation, the more complete it is, is essential for the selection of breeders and the ultrasonography of the reproductive system becomes an important addition in this examination.<\/jats:p>","DOI":"10.1111\/rda.13119","type":"journal-article","created":{"date-parts":[[2017,12,1]],"date-time":"2017-12-01T19:42:37Z","timestamp":1512157357000},"page":"393-400","source":"Crossref","is-referenced-by-count":4,"title":["The use of ultrasonography in the reproductive evaluation of boars"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0067-8121","authenticated-orcid":false,"given":"RO","family":"Pinho","sequence":"first","affiliation":[{"name":"Federal University of Vi\u00e7osa (UFV) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BS","family":"Camilo","sequence":"additional","affiliation":[{"name":"Federal University of Vi\u00e7osa (UFV) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DMA","family":"Lima","sequence":"additional","affiliation":[{"name":"Federal University of Vi\u00e7osa (UFV) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FAC","family":"Villadiego","sequence":"additional","affiliation":[{"name":"Federal University of Vi\u00e7osa (UFV) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JCM","family":"Vergara","sequence":"additional","affiliation":[{"name":"Federal University of Vi\u00e7osa (UFV) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HH","family":"Shiomi","sequence":"additional","affiliation":[{"name":"Federal University of Vi\u00e7osa (UFV) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"RE","family":"Cardoso","sequence":"additional","affiliation":[{"name":"University of Vi\u00e7osa (UNIVICOSA) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PS","family":"Lopes","sequence":"additional","affiliation":[{"name":"Federal University of Vi\u00e7osa (UFV) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SEF","family":"Guimar\u00e3es","sequence":"additional","affiliation":[{"name":"Federal University of Vi\u00e7osa (UFV) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JD","family":"Guimar\u00e3es","sequence":"additional","affiliation":[{"name":"Federal University of Vi\u00e7osa (UFV) Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,12]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"32","article-title":"Comparaci\u00f3n de dos t\u00e9cnicas em la determinaci\u00f3n de morfoanomal\u00edas del semen porcino","volume":"25","author":"Acosta M.
