Searching for improvements in semen cryopreservation, natural substances are commonly studied focusing to improve the sperm quality. The aim of this study were evaluated the effect of adding orange, pineapple, and beet juices in different concentrations and combinations to the ram semen cryopreservation extender. Five ejaculates from five adult rams were used. The semen pool was diluted in egg yolk-based extender and mixed with the following 15 treatments (at a final concentration of 400.10⁶ sptz/mL): orange 10% (O10) and 15% (O15); pineapple 10% (P10) and 15% (P15); beet 10% (B10) and 15% (B15); pineapple + orange 10% (PO10) and 15% (PO15); pineapple + beet 10% (PB10) and 15% (PB15); beet + orange 10% (BO10) and 15% (BO15); pineapple + beet + orange 10% (PBO10) and 15% (PBO15); and the control group (CON). Post-thaw in 0.25 mL straws semen quality analysis of cryopreserved semen was performed by CASA and flow cytometry. Analysis of variance (PROC GLM) was carried out and the averages were compared using the SNK test. Pearson's correlation test was also performed. No effect was noted in the addition of juices to the semen extender prior to cryopreservation. Post-thawed, although, statistically similar to the control group, the total motility of the B10 group reached acceptable standards of total motility. In addition, B10 group showed the highest values (p<0.05) of progressive motility than control group or other treatments. The addition of 10% beet juice to the ram semen extender can improve the cryopreservation of sperm motility.Keywords: antioxidant; freezing; sperm; semen extender.
