The high unsaturation levels of spermatozoal membrane make it very susceptible to oxidative damage and this problem increases with advancing age. In this study, the aim is to investigate whether parsley seed (PS) has a protective effect on semen quality, serum lipid profile and antioxidative status of old and young bucks. Male rabbits (n= 36) (18 young 9-12 mo old and 18 old 36-42 mo old) were each assigned to 3 dietary treatments (a control and 2 levels of PS: 0.3 and 0.6 kg/100 kg diet) to evaluate the ability of parsley to enhance bucks’ reproductive status. Most of the studied traits were adversely affected by age of rabbit bucks. On the other hand, the inclusion of PS significantly boosted ejaculate volume and improved mass motility concentration and total sperm output. Seminal plasma and blood serum total antioxidant capacity increased, while serum lipid peroxidase decreased with parsley treatments. In conclusion, dietary supplementation of parsley seed alleviates most semen quality parameters and counteracts oxidative stress, especially with the advance of age (seminal plasma and blood serum of total antioxidant capacity and malondialdehyde.
