Estimated Relative Conception Rates

Calculated by USDA, Estimated Relative Conception Rate (ERCR) is the measurement of a sire's ability to make pregnancies. ERCR is an excellent secondary selection tool to use when choosing sires to incorporate into a breeding program. Choosing high Lifetime Net Merit sires with positive ERCR numbers will help increase conception rates while still breeding for the complete cow that performs well in all areas.

The ERCR rating given to a sire represents the difference in conception rate of that sire compared to other A.I. sires used in the same herd. Each positive ERCR point indicates the expected conception rate for that sire to be one percent higher compared to "average" service sires used in the same herd. For example, a sire with a +3 ERCR can be expected to have an average conception rate three percent higher than "average" service sires used in the same herd.

Genex is a long-time leader in high LNM, high ERCR sires. This superior semen fertility gives producers the ultimate advantage - pregnancies and profitability.
