Lipoprotein</span></a><span style="background-color:#ffffff;"> (LDL)-based extender on some quality parameters of goat sperm after freezing. This study was conducted in a completely randomized design with four treatments, including: egg yolk-based extender without cysteine (EY), LDL-based extender containing zero (LDL-C0), five (LDL-C5), and 10 (LDL-C10) mM cysteine</span><span style="background:yellow"><span style="background-color:#ffffff;">, and six replicates</span></span><span style="background-color:#ffffff;">. Semen samples after dilution with the aforementioned extenders, were frozen. After thawing, total and progressive motility, sperm plasma membrane integrity, functionality, and sperm morphology were evaluated. Total motility was higher in LDL-C5 compared to EY and LDL-C10 (P <0.05). Progressive motility in all treatments using LDL-based extender was significantly higher than EY. Other motility parameters were higher in LDL-C5 compared to EY (P <0.05). However, no significant differences were observed between the LDL-C0, LDL-C5, and LDL-C10, except for the VSL, which was significantly lower in LDL-C0 compared to LDL-C5 (P <0.05). Sperm plasma membrane integrity, functionality, and sperm morphology were higher in all treatments using LDL-based extender compared to EY (P <0.05), with the highest values observed in LDL-C5. Overall, the results showed that adding five mM cysteine to the LDL-based extender can improve some quality parameters of goat sperm.</span></span></span></span></span></span></span></span></span></span><br /> <span style="background-color:#ffffff;">&nbsp;</span> آنتی‌اکسیدان, اسپرم, بز, کیفیت, انجماد Antioxidants, Freesing, Goat, Quality, Sperm 0 0 http://nbr.khu.ac.ir/browse.php?a_code=A-10-383-2&slc_lang=fa&sid=1 Javad Ghorbanzadeh جواد قربانزاده Javad.ghorbanzadeh@gmail.com 100319475328460012103 100319475328460012103 No University of Tehran دانشگاه تهران Saeed Zeinoaldini سعید زین الدینی zeinoaldini@ut.ac.ir 100319475328460012104 100319475328460012104 Yes University of Tehran دانشگاه تهران Mahdi Zhandi مهدی ژندی mzhandi@ut.ac.ir 100319475328460012105 100319475328460012105 No University of Tehran دانشگاه تهران Sayyed Mohammad Hadi Hussaini سید محمدهادی حسینی Hosseini.sayyed@ut.ac.ir 100319475328460012106 100319475328460012106 No University of Tehran دانشگاه تهران
