CHAPS Program
Thank you for your interest in the CHAPS2000 program.
CHAPS 2000 (Cow Herd Appraisal Performance Software) is a data intensive beef production record system designed to provide you with vital information about your managerial decisions and herd's performance.
CHAPS 2000 was developed by the North Dakota State University Extension Service through the North Dakota Beef Cattle Improvement Association (NDBCIA) and has been reviewed and approved by the National Cattlemen's Beef Association - National Integrated Resource Management - Coordinating Committee.

Most Recent 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 2010-2017. CHAPSTM compares each individual producer's performance against the benchmarks. The benchmark values for the NCBA-IRM-SPA traits are as follows:
93.7 | pregnancy % | 2.5 | average daily gain * | |||
0.58 | pregnancy loss % | 2.95 | weight per day age * | |||
93.1 | calving % | 82 | birth weight * | |||
3.0 | calf death loss % | 627 | adjusted 205-d weight * | |||
