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 91,414 cows exposed to bulls and
processed during 2007-2011. CHAPSTM compares each individual producer's performance
against the benchmarks. The benchmark values for the NCBA-IRM-SPA traits are as
follows:
