Dairy Herd Improvement Letter Vol 59

Excerpt from Dairy Herd Improvement Letter, Vol. 59: May 1983 Among official records, percent were unusable because of termination code 9, down from percent for 1981. (termination code 9 indicates that records should not be used for genetic evaluations because production information is not reliable.) Nearly 42 percent of official records had missing sire identification, which was the primary reason for exclusion of official records. Only percent of official records were excluded because of errors. Counts for records with missing sire identification or errors cannot be compared with counts for 1981 because of a change in editing procedures in 1981. About percent of official records were excluded because of conflicts, down from percent for 1981. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Dairy Herd Improvement Letter, Vol. 56: October 1980 These requirements were used for the Summer 1980 Sire Summary. Details such as minimum birth dates and perhaps minimum percentage increases in table 1 can be expected to change. The birth dates will probably increase annually by at least 1 year. The amount of information required for releasing initial summaries also may be increased. The possibility of more stringent requirements emphasizes the advisability of wide initial sampling.

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.
