The purpose of this study was to evaluate the motility and viability of stallion semen cryopreserved with 5% dimethyl-formamyde as cryoprotectant and posterior dilution to 2.5 and 1.25% as final concentration of cryoprotectant. After thawing, samples were diluted with two commercial extenders (FR4® and Botucrio® ) in two moments: initial (Ti) and final (Tf). A total of 15 distinct ejaculates from five stallions of national breeds were analysed. Motility was observed using a computer assistant system analysis and viability was analyzed using fluorescent probes. A significant (P<0.05) increase on total and progressive motility parameters was observed at the final time using Botu-Crio® compared with FR4®. Statistical difference (P>0.05) on membrane integrity between treatments was not observed.KEY WORDS: Cryoprotectant, diluent, equine, freezing, thawing.
