Revealing the GenCheckTM
Fertility Advantage
Each year, Genex Breeding Program Specialists collect data on over 1.5 million breedings. Each month, the latest breedings are analyzed using the best statistical analysis for non-return (to service) data. The outcome is individual bull fertility rankings. To date, these evaluations have only been used by our production division to optimize individual bull performance and, on occasion, to remove a bull from our active lineup due to poor fertility performance.
GenCheck is a fertility evaluation on all Genex bulls that have 300 or more services, but do not have an official Sire Conception Rate (SCR) calculated by USDA. GenCheck provides Genex members and customers with reliable fertility rankings for more bulls based on the only true way to measure a bull's fertility - through the cow.
GenCheck ranks bulls in the following categories: 
Excellent
Very Good
Average to Above Average
Average to Below Average
L Recommend limited use based on limited data
There are two outcomes for a bull ranked with an "L": With additional data his performance improves or the bull is removed from the lineup.
