Effect of egg yolk-based extender and seminal plasma removal on sperm viability of cooled donkey semen
نویسندگان
چکیده
Developing effective cooled semen protocols is essential to increase pregnancy rates and reproductive efficiency in donkeys. This study aimed evaluate the effect on sperm kinetic parameters membrane integrity donkey diluted with defined milk proteins extender 1% or 2% of egg yolk removal seminal plasma. Twenty-four ejaculates from six jackasses were collected. Each ejaculate was divided into four aliquots that (EY1) (EY2) yolk. One sample each group centrifuged, plasma removed (CEY1, CEY2 groups, respectively), samples then refrigerated at 5 °C for 24 h. Fresh assessed motility, morphology, integrity. Total progressive parameters, live cells not statistically different when an supplemented Seminal does affect total motility parameters. However, decreased (P<0.05) extended removed. Membrane affected centrifuged samples. In conclusion, obtained results suggest there no difference kinetics added Equiplus(R) extender. Also, by centrifugation did have any beneficial semen. Further studies are needed relate these vivo fertility tests

Effect of Egg Yolk and Removal of Seminal Fluid on Semen Cryopreservation in Norduz Goat
Cryopreservation of goat spermatozoa is a valuable tool for genetic management. Previous studies have shown the frezeeablity of spermatozoa from various goat breeds but also have difficulties with available protocols. Therefore, we want to investigate the effects of centrifugation and different egg yolk ratios (5% and 10%) on spermatological parameters of Norduz goat spermatozoa. A total number...

Background: Sperm cryopreservation is an important tool for breed improvement, nonetheless, spermatozoids of rams are extremely sensitive to cryopreservation. Aims: The present research was to compare a liposome-based (OptiXcell: OX) diluent, a commercial TRIS-egg yolk (Optidyl: OP) and a citrate egg yolk-based (CY) diluent on ovine semen quality through the cr...

The present study was designed to see whether adding glutathione to tris-citric egg yolk extender improves the quality of buffalo bull spermatozoa stored at 5°C for five days. Semen collected from Nili-Ravi buffalo (Bubalus bubalis) bulls (n = 5) was diluted (37C; 10 x 10 motile spermatozoa per ml) with extender having glutathione (0.0, 0.5, 1.0, 2.0 and 3.0mM). The extended semen was cooled fr...
