EFFECTS OF VITAMIN-E ON FOWL SEMEN STORAGE AT 4-DEGREES-C

Vitamin E was assayed for either in chicken spermatozoa or seminal plasma. Effects of vitamin E on the motility and fertilizing ability of chicken semen stored for 24 hours at 4-degrees-C were also studied. A mean of 0.25 mug vitamin E/10(9) cells was found in spermatozoa and 0.074 mug in seminal plasma. When the medium for in vitro storage of semen was supplemented with vitamin E the motility of spermatozoa was not affected. However, vitamin E improved the fertilizing ability of semen stored for 24 hours at 4-degrees-C, especially at the dose of 8 mug/ml of semen diluent.
