In the heat of an auction buyers need to be well aware of the genetic merit of the animal they are bidding on. Sales managers make every effort to make sure that the numbers in the sales catalogues are accurate and complete, however there is frequently added information that potential buyers did not have when they closely reviewed the catalogue before the sale. Additionally at times buyers may not be aware if the animal in the sales ring is of elite genetic merit.
In an attempt to give buyers interested in purchasing an elite young female to add to their breeding or marketing program from future sales this fall, the Bullvine has analyzed the heifers born and registered in the herd books in North America from March 2012 to August 2013. This group of females was chosen as they are likely to be the ages of heifers that will go through sales auctions over the next two months. The information from the CDN files was used as it is the animal information that is available free of charge.
Breed Toppers
Buyers are advised to have at their fingertips the total merit indexes for the very best animals so that they can value an animal that they are considering buying. The following table lists the averages for the top twenty-five heifers.
Figure 1.0 Top Twenty-Five North American Heifers (Born March 2012 to August 2013)
RANK NAME # OF DAUGHTERS
1 ATWOOD X DUNDEE 6
1 SANCHEZ X GOLDWYN 6
3 FEVER X DURHAM 5
3 GOLDWYN X DUNDEE 5
5 GOLDWYN X ASPEN 4
5 GOLDWYN X DAMION 4
5 PICOLO X ADVENT 4
8 BRAXTON X GOLDWYN 3
8 CONTENDER X ADVENT 3
8 DUNDEE X GOLDWYN 3
8 JASPER X GOLDWYN 3
8 SANCHEZ X DUNDEE 3
8 SPIRTE X ALLEGIANCE 3
Some points worthy of note from this table are: i) do not compare the Holstein and Jersey LPI values as the formulae differ; ii) the top 25 Holstein heifers are a very elite group with the DGV LPIs exceeding the gLPIs by 161 points; iii) Red Carrier Holsteins heifers have made considerable improvement in the last couple of years by the use of top BW sires on RC or Red females; iv) Polled Holsteins heifers have and are likely to continue to make rapid advancement again by the use of top horned BW sires on polled females; and v) the values listed for the Red Holstein heifers are parent averages as only two of the top twenty five heifers were genomically tested.
Use these benchmarks as you review the sales catalogues either on-line or using a hard copy of the catalogue.
Top Values
Often buyers wish to know benchmark numbers beyond the LPI value. The average index for the top five heifers for each trait in each animal category are as follows:

Remember these are the averages for the very best five animals in the various categories.
Sires of the Heifers
Buyers often want to know the sires of the top heifers. Knowing the sires of the top twenty-five heifers gives an indication of who the competition will be when you are marketing in the future from your purchases.
Sires with more that two daughters in the various categories are listed below. Each category has twenty five heifers. The bracketed number is the number of daughters the sire has on the list.
Holstein
- Seagull-Bay Supersire (8)
- De-Su BKM McCutchen (5)
RC Holstein
- De-Su BKM McCutchen (6)
- Seagull-Bay Supersire (5)
- Mountfield SSI Dorcy Mogul (4)
Polled Holstein
- Sea-Gull Bay Supersire (9)
- Da-So-Burn MOM Earnhardt P (5)
Red Holstein
- Dymentholm S Sympatico (8)
- Curr-Vale Destined (5)
- Tiger-Lily Ladd P-Red (5)
Jersey
- Sunset Canyon Dimension (5)
- All Lynns Valentino Marvel (4)
Health & Fertility
In the Holstein breed many breeders are starting to place increased emphasis on the Health and Fertility rating that CDN assigns animals. The value assigned can be found by looking up the animal on the CDN website. Factors used in calculating the H&F index include: Herd Life; SCS; Daughter Fertility; Milking Speed; and some other correlated traits.
The top five Holstein heifers in the various categories had average DGV Health and Fertility ratings as follows: Holstein 465; RC Holstein 413; Polled Holstein 423. Clearly an animal over 375 to 400 for H&F is at the top of the breed. An H%F value is not available for Red Holstein as so few of them are genomically tested.
The Bullvine Bottom Line
It is important to know the genetic superiority of an animal when purchasing or using them in your breeding or marketing program. It is the Bullvine’s hope that the above statistics will assist. Wise investment should give you a leg up on moving your herd forward.
