How storage conditions affect ejaculates up to evaluation is unclear. We assessed, in 25 commercial bulls electroejaculated in the field, the impact of time until evaluation (0\u20132 h, 4\u20136 h, and 24 h post-ejaculation), holding temperature (5 \u00b0C vs. room temperature), and extender (AndroMed\u00ae, BIOXcell\u00ae or INRA96\u00ae) on semen quality. Acrosome integrity, sperm viability and morphology, CASA-total and progressive motility, pH, and colony-forming units were assessed. Semen quality was preserved for up to 4\u20136 h post-ejaculation, except for INRA96\u00ae at 5 \u00b0C. Regardless of extender or temperature, motility decreased from 4 to 6 h up to 24 h, with the best values obtained with BIOXcell\u00ae at 5 \u00b0C. pH differed from 4 to 6 h up to 24 h, acidifying when stored at room temperature. Microbiological load was stable over time with AndroMed\u00ae and BIOXcell\u00ae, and increased at room temperature with INRA96\u00ae. Our results suggest that AndroMed\u00ae and BIOXcell\u00ae can preserve semen quality for up to 6 h, either at 5 \u00b0C or room temperature, while INRA96\u00ae only at room temperature. These results help to fix adequate protocols for short-term storage and shipment of bovine semen collected under field conditions.<\/p>\n<p>See full article <a href=\"https:\/\/www.mdpi.com\/2079-7737\/10\/7\/630\/htm\" target=\"_blank\" rel=\"noopener noreferrer\">here<\/a><\/p>\n<p>Biology 2021, 10(7), 630; https:\/\/doi.org\/10.3390\/biology10070630<br \/>\nReceived: 6 June 2021 \/ Revised: 28 June 2021 \/ Accepted: 3 July 2021 \/ Published: 7 July 2021<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Effects of Extender Type, Storage Time, and Temperature on Bull Semen Parameters Aitor Fernandez-Novo, Sergio Santos-Lopez, Clara Barrajon-Masa, Patricia Mozas, Eduardo de Mercado, Elisa Caceres, Aizic Garrafa, Juan Vicente Gonzalez-Martin, Natividad Perez-Villalobos, Agustin Oliet, Susana Astiz and Sonia Salome Perez-Garnelo Department of Veterinary Medicine, School of Biomedical and Health Sciences, Universidad Europea de Madrid, Madrid, <a href=\"https:\/\/www.micropticsl.com\/es\/faq-items\/effects-of-extender-type-storage-time-and-temperature-on-bull-semen-parameters\/\"> [&#8230;]<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":{"footnotes":""},"faq_category":[148,157],"class_list":["post-34209","avada_faq","type-avada_faq","status-publish","format-standard","hentry","faq_category-animal-es","faq_category-bull-es"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.8 -
