Release of GOT was determined during different treatments in ram semen extended (1:10) with lactose-egg yolk diluter containing 3.5% and 5% glycerol (v/v). Semen samples were collected by the electro-ejaculation technique and GOT was analysed colorimetrically. Highly significant difference (p less than 0.01) was found in the post-thaw percent motile spermatozoa and GOT release (IU/10(9) spermatozoa) between 3.5% and 5% glycerol containing equilibrated samples. The difference in percent motile spermatozoa was not significant between 3.5% and 5% glycerol levels in control, post-thaw unequilibrated and prefreeze equilibrated samples. Whereas the difference in GOT release between 3.5% and 5% glycerol concentrations was not significant in control and post-thaw unequilibrated samples and highly significant (p less than 0.01) in prefreeze equilibrated samples.
