CHAPS Program

Thank you for your interest in the CHAPS2000 program. The CHAPS2000 program is being prepared for re-release in mid 2016.

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.
