ABSTRACT The objective of this study was to evaluate how male age, semen extender, cooling (equilibration) time and freezing method influence the quality of Brahman bulls’ sperm after cryopreservation, as measured by Computer-Assisted Sperm Analysis (CASA) parameters. Six Brahman bulls, with an average age of 48.6±11.5 months, were used. Two ejaculates were collected for each animal on different days, with an interval of approximately one week between collections. Semen was diluted with three extenders: Andromed®, BioXcell®, and OptiXcell®. The samples […]

ABSTRACT This study analyzed the adenosine concentration on quality of ram semen in different refrigerated storage times at 5 °C. The design was in blocks with repeated-measures factorial design. Five levels of adenosine and four refrigeration times were considered as fixed effects and the animal as random effect (block). Ram semen was diluted with Andromed® diluent (control) and increasing adenosine levels (0.5, 0.75, 1, and 1.5%). The samples were taken from refrigeration after 4, 8, 12, and 16 h and […]
