P. aEffect of caffeine on motility and fertility frozen goat semen. c1994 aAddition of caffeine during deep preservation of goat semen in Tris medium was found to have a stimulatory effect on sperm motility. The sperm showed the highest motility in extender with 2mm caffeine (56,750%) in comparison to the extender with 5 mm(49.388%) or Tris control(47.805%). There was no significant effect on live sperm and acrosomal damage % due to addition of caffein in the extender. Fertility rate with Tris +2mm caffeine extended semen (59.183%) was higher than that with the Tris diluted semen(50.0%) aCaffeine aCryopreservation aGoats aReproduction aSpermatozoa aCafeína aCaprino aCriopreservação aEspermatozóide aFertilidade aReprodução animal aSêmen aFertility aMotilidade espermática aMovement1 aSINHA, A.
