Protective effects of fruit-juices on sperm viability of West African Dwarf goat bucks during cryopreservation
Résumé
The present study was conducted to determine the effects of adding fruit-juices to semen extenders on viability of buck spermatozoa during cryopreservation in two studies.Pooled semen samples obtained from West African Dwarf (WAD) goat bucks were diluted with Tris-egg yolk based extenders.In study I, the diluted semen samples were supplemented with orange (Citrus sinensis), cucumber (Cucumis sativus) and pineapple (Ananas comosus) juices (2.5, 5, 7.5 and 10 ml/100 ml).In study II, the diluted semen samples were supplemented with 5 ml/100 ml of different combinations of fruit-findings revealed that extenders supplemented with orange and pineapple at 10% consistently improved motility, acrosome integrity and membrane integrity, and reduced sperm abnormality compared to the control while no particular combination of these fruit-juices was consistently superior in all the parameters.
