The use of herbal bio-actives and phyto-contents to increase livestock productivity is a revived interest in veterinary research. The effect of wild strawberry {Fragaria vesca (FV)} pulp extract (PE) as antioxidant supplement in bovine semen cryopreservation diluent was explored. The experiment involved three fertile bulls. Three semen ejaculates per animal were collected. Each sample was diluted with Semen Transportation Diluent (STD) in 1:2 ratio. The (semen + STD) sample was vortexed and centrifuged (at 32g for 15 min) to remove 50 % supernatant. The remaining sample was re-diluted with semen cryopreservation diluent (SCD) in the ratio 1:4. Three aliquots of 0.3 ml were set aside from each (semen + STD + SCD) sample and were further treated with; 1: 0.7 mL of SCD (SCD group); 2: 0.7 mL SCD and 0.8 % FV-PE (FV-PE 0.8) and; 3: 0.7 mL SCD and 1.6 % FV-PE (FV-PE 1.6). Sperm quality parameters were evaluated before and after 48 h of cryopreservation. Results showed significantly enhanced mean percentage of sperm viability, progressive motility, velocity and fertilizability in FV-PE 0.8 and FV-PE 1.6 groups as compared with SCD group. The findings propose the protective and ameliorative potential of FV-PE for cryopreserved bovine sperms.
