Effects of Dietary Rose Extract on Qualititative Parameters of Frozen-Thawed Rooster Sperm

The objective of the present study was to investigate the effects of rose (Rosa damascena) extract on the quality of frozen-thawed rooster spermatozoa. Sixteen roosters divided into four aliquots and received a diet containing 0, 50, 100, 150 mg/kg of rose extract. On the 0, 14, 28, 42, 56 and 70th day of experiment, semen fluid were collected and sperm motility characteristics including total motility, progressive motility, linearity (LIN), straight line velocity (VSL), amplitude of lateral head displacement (ALH), curvilinear velocity (VCL), average path velocity (VAP), and sperm viability, acrosome integrity and lipid peroxidation were evaluated after cooling-thawing procedure. The treatments with 100 and 150 mg of rose extract significantly improved post-thaw total motility, ALH, VSL, and sperm viability, and reduced lipid membrane peroxidation (P
