concentrations of Royal Jelly supplementation in tris diluent on semen quality parameters of Arabi ram

This experiment was conducted to investigate the effects of different concentrations of royal jelly in tris extender on motility, viability, morphological abnormalities and membrane integrity of spermatozoa in Arabi rams. For this purpose, the semen of 10 Arabi rams were polled and then examined under 5 treatments including the tris diluent containing the concentrations of zero, 0.5, 1, 1.5 and 2% royal jelly in three times of zero, 24 and 48 hours in a completely randomized design. The results showed a significant difference in motility of spermatozoa among royal jelly treatments and control (P0.05). Concentrations 1 and 1.5% of royal jelly improved the amount of sperm plasma membrane integrity when compared with 0.5 and 2% of royal jelly concentrations (P
