Fifteen fertile rams (live weight 55.9 ± 1.21 kg, and 2.5-3 years old) were randomly allotted to three diets consisting of 0 (Control), 12.5 (PBP-12.5), and 25 % (PBP-25.5) pistachio by-products (PBP) in dry matter. Sperm motility parameters were detrimentally affected in animals feeding on PBP-25% diet (P<0.05). Sperm concentration of C17-1, C22-6-n-3, C18-2-Cis and C22-6 n-3 fatty acids decre...
In the process of cryopreservation, semen farm animals can be threatened by many factors, such as oxidative damage, which affect motility and plasma membrane function sperm. As an endogenous antioxidant in animals, glutathione (GSH) significantly improve quality thawed sperm when added to diluent semen. This study was aimed at examining effect GSH (given 0.5 mM, 1.5 mM 5 mM) on viability ram fo...
The interaction of preincubated ram sperm with zona-free hamster oocytes was studied by scanning and transmission electron microscopy. The behaviour of the sperm cells was quite different, depending on whether the acrosomal reaction had taken place or not. The apical ridge of intact spermatozoa contacted the oocyte surface, and egg microvilli spread onto the anterior segment but no fusion ensue...
