the purpose of this study was to determine the effects of different concentrations of vitamin e (vit. e) in the quality of preserved stallion semen at 5ᵒc for a period of 48 h. semen was collected and most (≥90%) seminal plasma removed by centrifugation at 600 × g. pooled samples divided in four equal parts and diluted with extenders that was supplemented with different concentrations of vit. e...

the aim of the present study was to evaluate the antioxidant effects of aqueous fruit extract of ziziphusjujuba on ethanol-induced oxidative stress and to examine its protective effects on sperm motility and plasma membrane integrity of male wistar rats. adult male rats (n = 28) were divided into four equal groups: the first group served as untreated controls, the second group of rats was given...

antioxidant effect of olive leaf extract (ole) was studied on motility, viability, plasma membrane integrity of spermatozoa and malondialdehyde production in 12 ross 308 roosters at their 30 weeks of age. semen samples were collected by abdominal massage in 5 times. in each session after the initial sperm assessment, collected samples were pooled and diluted with sexton extender.samples were sp...

objective: the aim of the present study was to investigate the effects of four equilibration times (2, 4, 8 and 16 hours) and two extenders (tris or bioxcell®) on cryopreservation of buffalo semen. materials and methods: in this experimental study, split pooled ejaculates (n=4), possessing more than 70% visual sperm motility were divided in two aliquots and diluted in bioxcell ® and tris-citric...

this experiment was conducted to evaluate the addition of seminal plasma to coated spermatozoa after 72 h. semen was collected from four taleshi rams by artificial vagina. to prepare coated spermatozoa, semen was collected in tube containing tris-fructose-15% egg yolk. after initial evaluation, the samples were mixed and centrifuged. after removal of supernatant and dilution, samples were divid...

to determine the effect of different levels of l-glutamine and glycerol on freezing coated sperm, semen were collected from 4 taleshi rams through artificial vagina contact with a tube containing tris-fructose-egg yolk 15%. ejaculates were pooled, centrifuged and supernatant was removed, then cell fractions were used. samples were split into 9 equal parts and 3 (g3), 5 (g5) or 7% (g7) glycerol ...

this study was conducted to evaluate the effect of egg yolk and cooling on ram coated spermatozoa. semen was collected from three ram by artificial vagina contacted with a tube containing tris- fructose-egg yolk 15%. samples were pooled, centrifuged by 700 g for 10 min and removed supernatant. then, samples were diluted by tris-glucose and centrifuged again to remove seminal plasma and egg yolk...
