ABSTRACT
We assessed the damage to frozen semen packaged in French straws stored for 2 yr in 60 on-the-farm semen tanks on 56 Washington dairy farms. Percentage of motilic spematozoa and percentage of spermatoza with intact acrosomes were not affected significantly by position of the semen on the rack (top or bottom goblet). The semen in 3 of the 60 tanks was lost to tank failure.
