Book excerpt: 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.
