Comparison of two procedures for freezing semen from cocks of high and low fertility with frozen semen.
Semen samples from groups of males chosen for high or low freezability of semen were frozen by two different methods, one using glycerol as the cryoprotectant and the other using DMSO. Fertilizing capacity was highest from semen collected from males of the high group and frozen in the presence of DMSO. Neither semen source nor method of freezing had any influence on the hatch of fertile eggs.
