The effect of royal jelly in tris extender on sperm characteristics of Dallagh rams

This research work was conducted to investigate the effect of using honeybee royal jelly as a protein source in tris extender on survival and motility characteristics of ram spermatozoa. Three Dallagh rams semen samples were pooled and subjected to six treatments, tris extender plus 0, 1,2, 3, 4 and 5 percent of royal jelly, in a randomized complete block design with sub-samples in an experimental unit. Results of experiment showed that effect of royal jelly treatment improved survival of ram spermatozoa significantly (PO.Ol). At post freezing stage, percentages of live and motile spermatozoa were improved with an increase of royal jelly in tris extender from 0 to 4% (34 and 31.32 to 37.32 and 34.41). Effect of tris extender with four percentage of royal jelly and tris extender with five percentage of royal jelly on live and motility of spermatozoa (37.45 and 34.56) was not significant (P<0.01). Therefore, the addition of four percent of royal jelly in tris extender is recommended for dilution and freezing ram semen.
