State and National
Standardized Lactation Averages by Breed for Cows Calving in 2004
H.D. Norman and L.L.M. Thornton |
Standardized lactation yields have been used to compare dairy cows having different lactation characteristics (i.e., age at calving, days milked, milking frequency, etc.) in an equitable manner. Average of standardized yield is compared in this report for each State and the nation for calvings in 2004 by breed. The data available originated in herds enrolled in the Dairy Herd Improvement (DHI) Program. The test-day data, used by the Animal Improvement Programs Laboratory to determine lactation records, are processed and provided by the dairy records processing centers (DRPC). DHI participation and DRPC activity have also been summarized using the same data source.
Only data used in calculation of national genetic evaluations are included in these State and national averages. Thus, records beyond fifth lactation or by cows that lacked either a first lactation record or lacked valid sire identification were excluded. For other editing requirements, see complete evaluation documentation.
Lactation records were calculated using the best prediction method starting in 1997 and were standardized for age-parity, calving month, previous days open, and times milked per day. Records shorter than 305 days were extended to 305 days as part of the best prediction process. Prior to 1997 the records were calculated using the test interval method. This change was responsible for a portion of the increases in yields observed between 1996 and 1997 because the current method gives a more favorable prediction for the lower producing cows. Protein testing for records contributing to genetic evaluations is at or near 100% except in California (87% for Guernseys, 88% for Holsteins, and 83% for Red and Whites) and Nevada (85% for Holsteins). Component percentages were computed from averages of standardized yields for milk and components.
Numbers of records and averages for yields and component percentages are in Tables 1 through 7 by State for Ayrshires, Brown Swiss, Guernseys, Holsteins, Jerseys, Milking Shorthorns, and Red and Whites, respectively. Numbers of records and national averages are in Tables 8A-8F by breed for selected years.
Breed yields are different between this report and the herd-average report because this report summarizes standardized lactation yield, whereas the herd-average report is determined from actual herd yields. Records contributing to herd-averages are not restricted to those usable for national genetic evaluations. Herd-average report is impacted also by the length of dry period. Relative yields among breeds differ between the two reports because of large breed differences in percentage of usable records and differences in age-parity factors. Also, herd-average reports tend to be more current (about 6 mo) than standardized yield published at the same time.
Ayrshire calvings were down 5.6% from last year, falling below the previous low set in 2001. Calvings for Ayrshires, Guernsey, and Red and Whites declined in 2004, dropping 5.6%, 4.7%, and 8.0%, respectively from the previous year. Numbers have declined steadily in the latter two breeds falling by nearly 50% since 1995. Jersey calvings increased 4.7% for 2004, picking up their earlier trend after experiencing little growth in 2003. Holstein calvings were up 2.1% over 2003 and 0.5% over 2002.
Milk yield increased slightly for all breeds except Milking Shorthorn, but differences from last year were 1% or less. While fat % was down slightly (<1%), higher milk production balanced fat production. Protein % remained at 2003 levels, thus protein production increased slightly. While feed availability and operating costs, milk and beef prices, Government programs, and characteristics of herds entering and leaving eligible testing programs can affect production averages in either direction, genetic change continues to have a positive effect on yield. The leveling off of average yields most likely reflects changes in management strategies due to feed availability and somewhat more emphasis on other traits such as health and longevity. For instance, average somatic cell count during 2004 was below 300,000 cells/ml for the first time in 10 years (Herd somatic cell count report). Interpretation of trends in lactation averages should be made in view of other changes affecting profitability.
