Benchmarks

For more effective utilization of individual herd data, production benchmark values utilizing the NCBA-IRM-SPA calculations were obtained from CHAPS^TM herds with a total of 74,421 cows exposed to bulls and processed during 2002-2006. CHAPS^TM compares each individual producer's performance against the benchmarks. The benchmark values for the NCBA-IRM-SPA traits are as follows:
