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 74,421 cows exposed to bulls and
processed during 2002-2006. CHAPSTM compares each individual producer's performance
against the benchmarks. The benchmark values for the NCBA-IRM-SPA traits are as
follows:
