Effects of adding royal jelly to Tris-egg yolk extender on Afshari ram sperm parameters after liquid storage of semen
Message:
Abstract:
The present study was conducted to evaluate the protective effects of royal jelly in Tris based extender on ram sperm parameters including motility, viability, morphology and plasma membrane integrity during 7 days liquid storage. 64 semen samples were collected with artificial vagina from 4 rams. After initial assessments, semen samples were mixed and then were diluted with Tris based extender having 0 (control), %1, %3 and %5 royal jelly. Motility was assessed with CASA system. Morphology and viability were assessed with Eosin-Negrosin staining method and plasma membrane integrity was assessed with HOST method. Diluted semen samples were kept in 37° for 1 hour and 4° C for 7 days. The results showed that motility percentage (51.25±2.86) in %3 royal jelly supplemented group was significantly higher than other treatment groups after 7 days’ liquid storage of semen (P< 0.05). The percentage of sperm cells with functional plasma membrane (46.53± 2.96) in %3 royal jelly supplemented group was significantly higher than control group (P< 0.05). The percentage of live sperm cells in %3 (56.96±3.37) and in 1% (54.68±2.83) royal jelly supplemented groups were higher than control group (P< 0.05). In conclusion, the results of present study showed that supplementation of %3 royal jelly to Tris based extender improves ram sperm parameters after 7 days’ liquid storage of semen.
