Consistently Create Pregnancies
Our exclusive bull fertility ranking system enables you to compare each bull’s conception ability and choose bulls that will consistently create pregnancies in your herd. PregCheck™ fertility rankings debuted in December 2014, as the first of their kind in the industry.
How PregCheck™ rankings work
PregCheck™ fertility rankings measure an individual sire’s frozen semen conception rate, and are are based on farm breeding and pregnancy data. The rankings use 100 as a base with every one point change equivalent to a 1% difference in conception rate.
For example, Bull A has a 104 PregCheck™ with 93% reliability and Bull B has a 99 PregCheck™ with 75% reliability. At 93% reliable, Bull A can be used with confidence. He is expected to perform 4% above the average conception rate of his contemporaries and 5% higher than Bull B.
For Bull B, at 75% reliability there is some uncertainty in his fertility ranking and over time additional breeding data will provide a more reliable evaluation. At this point, however, Bull B is trending below the average of his contemporaries with his 99 PregCheck™ ranking.
How PregCheck™ rankings help you
While all GENEX sires are procured with member profitability in mind, PregCheck™ fertility rankings offer you another sire selection option to help improve your bottom line.
