Abstract
A series of experiments was designed to evaluate the quality of cryopreserved rooster sperm and its fertility so that programs needing to bank germplasm and recreate animals can do so utilizing a minimal amount of cryopreserved semen. In experiment 1, rooster semen from the National Animal Germplasm Program genebank was thawed and glycerol was removed using a discontinuous Accudenz column or by stepwise dilution. The postthaw sperm motilities, plasma membrane integrity, and concentration were determined before and after deglycerolization. Line differences in postthaw sperm concentration and progressive motility were observed before deglycerolization (P
