Quality and Fertility of Post Thaw Sephadex Filtered Bull Semen
The present investigation was carried out to assess the effect of Sephadex (G-15) filtration on the post thaw bull semen quality and conception rate. Post thaw unfiltered (control) and Sephadex filtered semen from four healthy bulls (three cross bred and one pure bred Holstein Friesian) were subjected to microscopic examination viz. sperm concentration, individual motility, live sperm count and...
متن کاملSupplemental Glutathione Improves Post-Thaw Quality of Holstein Bulls Sperm in a Nanomicelle based Extender
Adding antioxidants to semen extenders could reduce post-thaw sperm damages. Glutathione is an important intracellular antioxidant that has free radicals scavenging properties and multiple effects on DNA and protein synthesis. In the present study, effects different levels of reduced glutathione (GSH) containing 0 (control), 1.0, 2.5, or 5.0 mM in a nanomicelle-based extender on post-thaw quali...
متن کاملAssessment of Post-1haw Semen Quality of Buffalo and Sahiw Al Bulls Using New Semen Assays
Different semen assays were employed to determine the post -thaw fitness of buffalo and Sahiwal bull spermatozoa. Semen (two ejaculates) was collected from buffalo and Sahiwal bulls (six each) once a week for three consecutive weeks. Semen was diluted in lactose-fructose-egg yolk glycerol extender, equilibrated at 4 ac for 4 hr and frozen in liquid nitrogen vapors. A highly significant differen...

متن کاملEffect of Adding Coenzyme Q10 and Ellagic Acid during Cryopreservation on Post-Thaw Quality of Ram Semen
The aim of this study was to determine the effects of co-Q10 and ellagic acid on sperm parameters after the freeze–thawing of Ghezel ram sperm. Twenty ejaculates from five Ghezel rams were collected in this study. Semen samples, which were diluted with a soybean lecithin (SL) based extender containing 0.25 mM ellagic acid, 0.5 μM co-Q10, 0.25 mM ellagic acid + 0.5 μM co-Q10 and no antioxidant (...
