Abstract
Objective: This study aimed to assess the impact of β;-caryophyllene (BC) supplementation in the extender on the post-cryopreservation quality of semen from Dorper rams. Methods: Six Dorper rams were utilized for semen collection over 16 weeks, with BC concentrations determined via the MTT test. Animals were divided into a control group and three treatment groups receiving BC at concentrations of 1.0 mM, 2.0 mM, and 3.0 mM in the Tris-gem diluent. Semen was cryopreserved and stored in liquid nitrogen for at least 15 days. After thawing, in vitro assessments including CASA, acrosomal integrity, plasma membrane integrity, mitochondrial membrane potential, and thermo-resistance tests were conducted. Additionally, the TBARS assay was performed to evaluate oxidative stress. Results: While BC supplementation did not significantly affect sperm motility, it notably improved mitochondrial potential and mitigated oxidative stress in cryopreserved ram semen. Conclusion: Incorporating β-caryophyllene into the extender exhibited beneficial effects on the quality of Dorper ram semen post-cryopreservation, enhancing mitochondrial functionality and reducing oxidative stress.
