The Benchmarks

For more effective utilization of individual herd data, production benchmark values utilizing the NCBA-IRM-SPA calculations were obtained from CHAPSTM herds with a total of 88,000 cows exposed to bulls and processed during 2010-2014. CHAPSTM compares each individual producer's performance against the benchmarks. The benchmark values for the NCBA-IRM-SPA traits are as follows:
