Excerpt from Dairy Herd Improvement Letter, Vol. 53 Table 2 shows errors and conflicts noted in 1976 rather than the number of records in error. As many as four errors or conflicts or both may be coded for a single record. Table 2 shows that missing identification numbers for sires of grade cows caused rejection of records. The next most frequent cause of rejection - was that the cow number was all zeros. Next, with a loss of records, was conflicting or questionable birth date. The records rejected during the main edit are returned to the appropriate processing center for correction. Increased care in identifying (including the reporting of sire and dam numbers) and reporting all animals in each herd would greatly increase the number of records used for bull and cow evaluation.
