The scrotal circumference (SC) and biometry characteristics of the bulls were measured to calculate the testicular volume. Doppler ultrasonography was used to obtain the haemodynamic values of the testicular artery. The skin thickness and volume were lower (<jats:italic>p<\/jats:italic>&lt;.01) in the younger bulls (12\u00a0months:4.68\u00a0\u00b1\u00a00.68\u00a0mm; 168.76\u00a0\u00b1\u00a047.96\u00a0cm<jats:sup>3<\/jats:sup>) versus 24\u00a0months (5.05\u00a0\u00b1\u00a00.89; 499.73\u00a0\u00b1\u00a0129.24\u00a0cm<jats:sup>3<\/jats:sup>) animals (<jats:italic>p<\/jats:italic>&lt;.01). During diastole, mean velocity was lower in the 12\u00a0months (7.98\u00a0\u00b1\u00a03.83) than in the 24\u00a0months (11.37\u00a0\u00b1\u00a04.15) animals (<jats:italic>p<\/jats:italic>&lt;.05). The 12\u2010month\u2010old animals had higher pulsatility and resistivity indices (0.49\u00a0\u00b1\u00a00.02; 0.51\u00a0\u00b1\u00a00.20) compared to the 24\u2010month\u2010old animals (0.32\u00a0\u00b1\u00a00.16; 0.40\u00a0\u00b1\u00a00.15) (<jats:italic>p<\/jats:italic>&lt; .05). The final testicular end velocity was lower in animals with long\/moderate\u2010shaped (L\/M) (7.31\u00a0\u00b1\u00a02.91) than in those moderate\/oval\u2010shaped (M\/O) (11.48\u00a0\u00b1\u00a03.88) testicles (<jats:italic>p<\/jats:italic>&lt; .05). Animals with L\/M testes presented higher pulsatility values and resistivity indices (0.51\u00a0\u00b1\u00a00.05; 0.55\u00a0\u00b1\u00a00.04) compared to animals with M\/O shape (0.29\u00a0\u00b1\u00a00.20; 0.36\u00a0\u00b1\u00a00.15). We showed that the blood flow of the supra testicular artery between the two evaluated ages differed, and that 24\u2010month\u2010old bulls presented better thermoregulation capacity. Animals with a long\/moderate testicular format presented a greater vascular resistance, which was imposed on the blood flow due to the anatomical differences in the testicular artery, resulting in lower velocity, and indicating better heat dissipation in this format.<\/jats:p>","DOI":"10.1111\/rda.13947","type":"journal-article","created":{"date-parts":[[2021,5,1]],"date-time":"2021-05-01T15:10:38Z","timestamp":1619881838000},"page":"1034-1039","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Testicular shape, scrotal skin thickness and testicular artery blood flow changes in bulls of different ages"],"prefix":"10.1111","volume":"56","author":[{"given":"Lu\u00eds Afonso Marques","family":"Claus","sequence":"first","affiliation":[{"name":"Deparment of Animal Science State University of Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6799-2759","authenticated-orcid":false,"given":"Fl\u00e1vio Ant\u00f4nio","family":"Barca Junior","sequence":"additional","affiliation":[{"name":"Animal Production Laboratory Animal College of Veterinary Medicine University of Northern Paran\u00e1 Arapongas Paran\u00e1 Brazil"},{"name":"REPROA \u2010 Animal Reproduction Laboratory Deparment of Animal Science State University of Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Celso Koetz","family":"Junior","sequence":"additional","affiliation":[{"name":"Animal Production Laboratory Animal College of Veterinary Medicine University of Northern Paran\u00e1 Arapongas Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8020-9845","authenticated-orcid":false,"given":"Gabriel Ribas","family":"Pereira","sequence":"additional","affiliation":[{"name":"Animal Production Laboratory Animal College of Veterinary Medicine University of Northern Paran\u00e1 Arapongas Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patr\u00edcia da Cruz","family":"F\u00e1varo","sequence":"additional","affiliation":[{"name":"Animal Production Laboratory Animal College of Veterinary Medicine University of Northern Paran\u00e1 Arapongas Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabio Proc\u00f3pio","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Animal Production Laboratory Animal College of Veterinary Medicine University of Northern Paran\u00e1 Arapongas Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victor Hugo Gon\u00e7alves","family":"Galdioli","sequence":"additional","affiliation":[{"name":"Animal Production Laboratory Animal College of Veterinary Medicine University of Northern Paran\u00e1 Arapongas Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5097-5119","authenticated-orcid":false,"given":"Marcelo Marcondes","family":"Seneda","sequence":"additional","affiliation":[{"name":"REPROA \u2010 Animal Reproduction Laboratory Deparment of Animal Science State University of Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edson Lu\u00eds de Azambuja","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Deparment of Animal Science State University of Londrina Londrina Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,5,18]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1590\/1413-70542016404003916"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.202.2.9015090"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0093-691X(98)00009-0"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0093-691X(96)00245-2"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0093-691X(03)00231-0"},{"key":"e_1_2_9_7_1","volume-title":"Cartas Clim\u00e1ticas do Paran\u00e1","author":"Caviglione J.
