Abstract

In this work, the influence of the donor male on the fertility of cryopreserved rabbit sperm after artificial insemination into females from different genotypes was evaluated. Females belonged to three lines selected for maternal characteristics (A, V and H) and all the possible crosses between them. Sperm from five males from the line selected for one of the maternal characteristics (line V) was frozen individually in a Tris-citric acid-glucose diluent with 1.75 m of DMSO and 0.05 m of sucrose (final concentrations). After artificial insemination of the cryopreserved sperm, fertility rates and prolificacy were similar for all groups of females (56% of fertility rate and 7.2 total born). Significant differences between males were observed for both fertility (p < 0.05) and kindling (p < 0.01) rate. These differences could be because of differences in the freezing resistance of sperm from the different males.
