In August 2008 the United States Department of Agriculture released for the first time Sire Conception Rates (SCR), replacing Estimated Relative Conception Rates (ERCR). The SCR evaluation has proven to be better than ERCR as it is a more accurate measure of a bull’s ability to actually get a cow in calf, as opposed to just measuring non-return rates. Repromax™, Semex’s lineup of high fertility sires, benefits from this new system, as the SCR evaluation is included, forming the world’s only international fertility information.

Semex sires rank well above average for SCR, adding to the confidence breeders can have in using our Repromax™ lineup. The Sire Conception Rate (SCR) rating is an important fertility figure, but should just be part of the decision making process when choosing a mating sire. Therefore, it’s important to keep in mind just what the SCR figure represents and how to use it to your advantage.
