Effect of using different levels of royal jelly in semen extender on some quality and quantity parameters of Mahabadi goat semen

The aim of this study was to compare the effects of using different levels of royal jelly in semen extender on viatal characteristics of goat sperm after freezing. Semen was collected from four adult bucks twice a week and samples pooled together. Sperm samples (six repeats) containing royal jelly in four levels (0.5, 1, 1.5 and 2%) had been frozen. After semen samples freezing – were thawed and examined in terms of mobility, survival and integrity of the membrane. Average total motility and survival at 1% royal jelly were higher than other treatment and control groups (P<0.05). A significant difference in terms of linearity motility of sperm and plasma membrane integrity was not observed between the treated groups and control group. A significant reduction was observed in the rate of other parameters velocity in Diluent contain royal jelly with the control group (P<0.05). Therefore, the use of royal jelly in goat semen diluent can improve some sperm parameters after freezing process.
