چکیده انگلیسی
This study evaluates the effects of two cooling devices and temperature for testicles storage on epididymal sperm quality after 24 hours; different levels of seminal plasma (0% and 10%) were evaluated on sperm after recovering. Testicles from six stallions were recovered immediately after castration (2) or at the slaughterhouse (4); of the same animal, one testicle was placed in Equitainer (+8°C), the other in a styrofoam box with ice (+3°C). After 24 hours, the temperature of parenchyma was measured, and testicles and epididymal were weighted. Sperm were flushed from the cauda epididymides with Kenney extender, total sperm number recorded and motility and viability evaluated immediately after flushing (T0) with or without 10% SP (G1 Eq 0%, G2 Eq 10%, G3 Ice 0%, G4 Ice 10%). Motility and viability were evaluated after 24 hours and 48 hours of storage at +4°C. Temperature of the parenchyma was lower in testicles stored in ice compared to Equitainer (3.2 ± 0.6°C and 8.6 ± 2.5°C, respectively; P < .05). Motility and viability at T0 were similar (P > .05) in G1 and G3, whereas addition of SP after recovery significantly improved motility only in samples stored in Equitainer (G2). Viability was higher (P < .05) in G2 than in G4. At T24 and T48, no differences (P > .05) in sperm quality were found between storage methods or samples with or without SP. In conclusion, equine testicles can be safely stored either at lower (+3°C) or higher (+8°C) temperature than +5°C. This can be useful, especially when testicles are shipped in a hot climate, where devices cannot guarantee optimal refrigeration conditions.
