Book excerpt: Excerpt from Dairy Herd Improvement Letter, Vol. 60: December 1984 The number of herds with averages for protein has increased almost 69 percent during the past year. Several factors may explain this trend.

The number of milk processors that pay a protein differential also has increased. In addition, interest in selection for protein yield has increased.

This book was released on 2018-01-12 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Dairy Herd Improvement Letter, October 1984, Vol. 60: Changes in Genetic Evaluation Procedures for January 1984; Counts of 305-Day Lactation Records Excluded From Genetic Evaluations for 1983; State and National Standardized Lactation Averages by Breed for Cows on Official Test, Calving in 1982 Among official records, percent were unusable because of termination code 9, down from percent for 1982. (termination code 9 indicates that a record should not be used for genetic evaluations because production information is not reliable or the record did not conform to Official Dairy Herd Improvement Rules.) Approximately 40 percent of official records had missing sire identification, which was the primary reason for exclusion, down from approximately 42 percent in 1982. Only percent of official records were excluded because of errors, the same as for 1982. The number excluded because of errors varied considerably among States. Missing birth dates and missing animal identification were the primary causes of errors for States with large numbers of records with errors. About percent of official records were excluded because of conflicts, down from percent for 1982. If a record was not used in computing genetic evaluations for a reason other than conflict, such as missing sire identification, only that record was excluded. However, when a record was compared with other records for the same cow and a conflict, such as differing birth date or parent identification, was detected, all records for that cow were excluded, including incoming records and all records already in the Animal Improvement Programs Laboratory files.
