This book was released on 2018-01-09 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

Book excerpt: 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.

Download or read book Dairy Herd Improvement Letter, Vol. 48 written by U. S. Agricultural Research Service and published by Forgotten Books. This book was released on 2018-09-11 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Dairy Herd Improvement Letter, Vol. 48: September-October 1972 The types and frequencies of error or reject conditions noted in 1971 are shown in table 3. Missing identification numbers for sires of grade cows caused the most records to be rejected compared with in 1970; next in order was conflicting or questionable birth dates. These appeared times less than in 1970. The number of records for registered cows rejected because of a zero dam or sire number was -528 more than in 1970. The inclusion of blanks in the record and alphabetic characters in the two high-order positions of the sire number continued to decrease in 1971. Table 3 shows error conditions rather than the number of records in error. As many as four error conditions may be coded for a single record. This is reflected in the fact that the number of error conditions in table 3 is more than the number of records shown above as not being used for bull and cow evaluation. The records rejected during the main edit are returned to the appropriate processing center for correction.

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.
