CHAPS (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. The program was developed in 1985 by NDSU Extension and the North Dakota Beef Cattle Improvement Association. CHAPS collects, stores, and evaluates individual herd data, according to Beef Improvement Federation guidelines. CHAPS data specialists compile herd data and calculate yearly averages to establish the CHAPS benchmarks: 5-year rolling averages of the yearly herd averages. CHAPS reproduction and production benchmarks include calving distribution, reproductive percentages (pregnancy, pregnancy loss, calving, calf death loss, weaning, and replacement percentages), calf growth (birth weight, weaning weight, weight per day of age, average daily gain, age at weaning, and pounds weaned per cow exposed) and production data (frame score, cow age, cow weight, and cow body condition score). As industry standards, the CHAPS benchmarks allow producers to examine numerous reproduction and production traits to evaluate herd performance, set goals, and make necessary changes to achieve these goals.
