THE (Total Herd Evaluation) is a complete-herd reporting system to evaluate performance traits. Participating in THE provides performance reports (adjusted weights, indexes and ranks) and EPDs (Expected Progeny Differences) which are run twice per year.
The THE program allows a member to participate at whichever level meets their needs as a purebred breeder. It is a cow-based program and the only requirement is that if any weight (i.e. birth weight) is reported, then it must be reported on all calves, not just those that are registered. All traits (birth, weaning or yearling) are not mandatory. It is the comparison of calves given the same opportunity to perform that generate EPDs which can then be compared across herds.
EPDs are run weekly & published every Monday. New data is extracted every Thursday night at 9:00 pm Calgary time.
Depending on whether data is recorded before or after this cut-off, results will be included in new EPDs published 12-18 days later.
