| Abstract | ||||
| Antibiotics are an essential component of semen extender to avoid a possible depreciation of semen quality. However, antibiotics have been questioned because of an ever-increasing bacterial resistance. In this term, probiotics (Lactococcus lactis) can be used as an alternative to antibiotics due to their antimicrobial properties. In this study, the effects of probiotics (Lactococcus lactis) as an antibiotic alternative compared to control and antibiotic group (gentamicin-GEN) on semen quality in rabbits was studied. The Tris fructose extender was prepared and the supplemented with antibiotic (AB, 250µg gentamycin) probiotic (pro, 109 colony-forming units of Lactococcus lactic) per ml of semen or without supplementation as a control and the semen was cooled at 5○C for three days. The results showed that probiotics had the same antibiotic-like effect on the quality of cryopreserved semen, except for noticeable differences in sperm motility and gross and vital abnormalities. In conclusion, probiotics (109 colony-forming units of Lactococcus lactis) improved semen quality over time thus it could be used as safe alternative to conventional antibiotics in rabbit semen extenders. | ||||
