Effect of different levels of bovine serum albumin (BSA) on semen quality of Arabi ram during storage in 5°C
During the semen storage, oxidative damages are the major causes of decrease in sperm quality and its fertility potential. The aim of this study was to evaluate the effect of different levels of bovine serum albumin (BSA) as an antioxidant on semen characteristics of Arabi ram in various times of semen storage in liquid condition under 5°C. Semen samples were collected weekly from 8 Arabi rams for 8 weeks and pooled. After dilution, the semen sample was divided into 5 parts which received the different levels of BSA (0, 0.5, 1, 1.5 or 2 percent). In each part, semen quality characteristics were evaluated at different storage times (1, 24, 48, 72 or 96 h). In 1h of storage, BSA levels only decreased the morphological defects of spermatozoa than control (P0.05). Overall, with increasing the storage times of Arabi ram semen, lower levels of BSA (below than 2 percent and preferably 0.5 and 1 percent) significantly improved the sperm quality parameters without effect on pH of semen.
