Preservation of canine spermatozoa at 50C is a helpful method for dog breeding management. However, in many species, oxidative damage due to generation of reactive oxygen species (ROS) and long term storage which specifically cause DNA damage, and lipid peroxidation during preservation techniques can cause a decline of sperm motility and fertility capacity. In this study, the effect of antioxid...

In the present study, we evaluated effect of various concentrations date palm pollen (DPP) aqueous extract on rabbit sperm during storage at 4°C for 48 h. Semen was collected from old and young bucks using an artificial vagina initially quality. The were diluted in Tris buffer supplemented with (20, 40, 80 mg/mL) DPP extract. extended samples stored Sperm motility motion kinetics assessed after...

This study investigated the effects of egg yolk and coconut milk-based extenders on motility morphology chilled post thawed turkey (Meleagris gallopavo) semen in Maiduguri, Nigeria. A total 112 samples were collected from seven matured toms, twice weekly for 2 months using dorso-abdominal massage method. Freshly pooled, divided into three aliquots diluted with modified Ringer’s buffer, extender...

the aim of this investigation was to assess the effect of different antioxidants on the motility andmembrane integrity of the ram semen during storage at 5ºc for 0, 12, 24, 48 and 72 hrs after collection anddilution. a total of 57 ejaculates from 12 bakhtiary rams was collected by artificial vagina and were extended1 : 3 with egg yolk-citrate buffer, which was containing one of the following an...

Marinated broiler breast fillets were evaluated using both air- and immersion-chilling treatments. Ninety fillets from air-chilled broiler carcasses and 90 fillets from immersion-chilled broiler carcasses were obtained from a processor to determine differences in meat quality, sensory, and shelf life. At 24 h postmortem, the fillets were vacuum-tumbled (25 in Hg, 30 min, 14 rpm, 4 degrees C) in...

Methanol is a widely used cryoprotectant (CPA) in cryopreservation of fish embryos, however little is known about its effect at the molecular level. This study investigated the effect of methanol on sox gene and protein expression in zebrafish embryos (50% epiboly) when they were chilled for 3 h and subsequently warmed and cultured to the hatching stages. Initial experiments were carried out to...
