Book Description
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.

Excerpt from Dairy Herd Improvement Letter, Vol. 49: October, November, December, 1973 The early availability of information is made possible by using all rip records for 40 days or longer, in addition to both complete and terminated records for 15 days or longer. This procedure contrasts with the use of data in the Sire Summary List, (for which rip records and records begun in the previous 12 months are not used in order to avoid a high proportion of cull-cow records) About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.
