BECAUSE FAST FERMENTATION MATTERS
gender SELECTED designees have sex-sorted semen available. Select Sires continually collects conception data from herds using gender SELECTED semen to calculate sexed semen fertility deviations and removes bulls from the lineup that perform unacceptably.
Look for the gender SELECTED 4M icon to identify sires with sex-sorted semen available in 4 million sperm doses, twice as many cells as gender SELECTED Ultraplus. That’s 4 million female sex-sorted sperm packed into each unit!
