Effects of dietary rosemary (Rosmarinus officinalis) essential oil were evaluated on the semen quality of broiler breeder rooster using sixteen 24-wk Ross 308 male birds. Experimental groups were consisting of four treatments (0, 50, 100 and 200 mg rosemary essential oil/kg of feed) with four replicates per each group. Semen samples were collected on days 0, 14, 28, 42 and 56 of experiment. Results showed that 100mg rosemary significantly improved several traits of sperm such as Amplitude of Lateral Head Displacement (ALH), Average Path Velocity (VAP), and Straight Line Velocity (VSL) on days 42 and 56, and sperm Membrane Integrity (MI), sperm viability, Linearity (LIN) and Total Motility (TM) on day 56 (P<0.05) and significantly decreased dead sperms (P<0.05). However, sperm concentration, apoptosis and morphological changes, Sperm Track Straightness (STR), Curvilinear Velocity (VCL), Progressive motility (PM) and malondialdehyde (MDA) level were not affected by experimental treatment. It can be concluded that 100 mg rosemary essential oil/kg of diet could be efficient for improvement of some qualitative sperm parameters.
