Semen samples were collected from sexually mature drones. Pooled semen was diluted with extender without RJ (control) or supplemented with different concentrations of RJ (1, 2, 4 or 8%). Sperm motility, plasma membrane functional integrity, and acrosomal integrity were evaluated. At post thaw, the highest sperm motility and acrosomal integrity rates were obtained in the RJ1 group. Functional integrity of sperm membrane was better preserved in the RJ1 and RJ2 groups compare to the other groups. The study shows that RJ supplemented extenders have beneficial effects on drone semen parameters. The results of the present study demonstrated advantage of using 1% RJ supplemented extender.eninfo:eu-repo/semantics/closedAccessLife sciences & biomedicine - other topicsPhysiologyHoney beeApis melliferaRoyal jellyDrone semenCryopreservationPostthaw qualityRam semenAntioxidantQueensPlasmaAnimalsBeesCell membraneCryopreservationCryoprotective agentsFatty acidsMaleSemenSemen preservationSperm motilitySpermatozoaArticle0004651546000032-s2.0-8506280669828318730876908BiologyPhysiologyQueen Honey Bees; Apis Mellifera; HoneybeeRoyal jellyCryoprotective agentFatty acidAcrosomal integrityAcrosomeAnimal cellArticleCell functionCell membraneConcentration (parameter)Controlled studyCryopreservationDroneFreeze thawingHoneybeeMaleNonhumanPriority journalSemen analysisSperm preservationSperm qualitySpermatozoonSpermatozoon motilityAnimalBeeCryopreservationDrug effectCytologyPhysiologyProceduresSpermSpermatozoon
