The study aimed to investigate the effect of asparagus extract on quality semen of Arabian rams at different storage times at a temperature of 4 degrees Celsius. Sperm collection was performed from 10 Arab rams with an average age of 2.5 years per week (once a week) for six weeks. After adding 0, 1.5, 3 and 4.5% asparagus extract to the semen diluent, sperm quality parameters were evaluated at 0, 24, 48, and 72 hours after storage in liquid condition. At zero hour, sperm viability in diluent had 3% asparagus extract was higher than diluent containing 0 and 4.5% extract (P<0.05). After 24 hours of semen storage, the parameters of total motility, progressive motility, plasma membrane integrity and viability were higher in sperm diluent containing 1.5 and 3% of the extract (P<0.05). Qualitative parameters of sperm in 48 hours after sperm collection and storage in diluent contain 3% of extract had significant and better performance (P<0.05). The highest rate of plasma membrane integrity, progressive motility and total sperm motility was observed in diluent containing 3% extract in 72 hours after sperm storage (P<0.05). According to the results of this study, the use of asparagus extract in the diluent at the rate of 3% improves the sperm quality of Arabian rams after cooling conditions.

This study aimed to evaluate the effect of L-arginine on qualitative characteristics and fatty acid profile of Ross 308 aged broiler breeder roosters’ sperm. Twelve breeder roosters at age of 52 week were used in a completely randomized design with three treatments and four replicates in each treatment for eight consecutive weeks. Experimental groups were consisting diets with levels of 0.52 (Ross recommendation 308), 0.68 and 0.83 present of arginine amino acids. Semen collection was performed every 14 days and in weeks 54, 56, 58 and 60 were tested. At the end of the trial, fatty acid profile of sperm was also evaluated. On week 56, semen volume in roosters with 0.68 present arginine was higher than other treatments (P<0.05). On week 60, levels of 0.52 and 0.68 percent arginine in semen volume, percentage of total and progressive motility were higher than the level of 0.83 percent of arginine (P<0.05). On week 58, the percentage of abnormal sperm were lower in 0.68 and 0.83 percent arginine treatment compared to 0.52 percent arginine (P<0.05). Semen concentration, sperm plasma membrane functionality and sperm fatty acid profile were not affected by treatments used in this study. It can be concluded that 0.68 percent of arginine (30% higher than recommendation) of diet improve some qualitative sperm parameters in aged broiler breeder roosters.

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.
