ResumoALTHOUGH very successful fertility results have been obtained with mammalian spermatozoa stored in CO2 extenders, no attempts have been made to develop a CO2 extender for fowl spermatozoa. An extender that preserved the fertility of bovine semen up to six or seven days at room temperature was developed by Van Demark and Sharma (1957). This extender, which was called the Illinois Variable Temperature (IVT) extender, contained in part, sodium bicarbonate saturated with CO2 to immobilize the spermatozoa. An extender for bull semen, which evolved its own CO2 by the reaction of sodium bicarbonate with citric acid, was developed by Foote et al. (1958). Sodium bicarbonate in semen extenders has been found to improve the livability (Kampschmidt et al., 1951), motility (Willett and Ohms, 1956) and fertility (Gokhale, 1958; Van Demark and Bartlett, 1958) of bovine spermatozoa. Bogdonoff and Shaffner (1954) studied the effect of various physiological diluents on chicken spermatozoa…
