The gap in fertility between conventional and sex-sorted bovine sperm, known to be on the order of 10 percentage points, has never been bridged, even by increasing the number of sex-sorted sperm per inseminate. A total of 6, Holstein heifers were inseminated across 41 commercial herds in the United States. This is the first report of an improvement in conception rates using sex-sorted bovine semen in a decade since it became commercially available.
A second field trial to investigate dose rate effects and compare against conventional semen was performed using 5 dairy bulls located at German Genetics International GmbH in Cloppenburg Germany. Each ejaculate was split 4 ways, sex-sorted, and frozen in 0. The day nonreturn rate was calculated by sire and treatment combination, and assigned a weight based on the total number of AI for each combination thereof.
Table 1 contains the nonreturn rate weighted means and the relative fertility compared to conventional sperm. This is the first time a dose response effect with sex-sorted bovine sperm and parity in conception rates with conventional semen has been demonstrated.
