Trait Leaders

Four trait leader reports are available to provide the top 200 animals of specific classes or types in the Hereford breed based on the $Profit Indexes which use multiple EPD criteria in their calculation. Click through the different sections to learn more on the trait leaders.

The Baldy Maternal Index (BMI$)

The Baldy maternal Index (BMI$) is a maternally focused index that has a production system based off of 1000 Hereford x Angus females with a progeny harvest endpoint directed towards CHB. This index is more critical of Calving Ease (CE) than the Brahman Influence Index (BII$) and also has significant weight on fertility. There is positive weight on Weaning Weight (WW) and a slightly negative weight on Yearling Weight (YW) which promotes early growth and then a slow down on growth to keep mature size manageable. The weight for Marbling (MARB) is greater than the weight for Ribeye Area (REA). This is true because of the price difference between the choice-select spread and the fact that there is very little incentive to produce cattle better than a yield grade 3. The question comes up concerning the fact that our branded beef program (CHB) has been successful because of the acceptance of Select cattle. In answer to this, we are using a crossbreeding production system that could sell cattle on several grids and that our CHB program is installing a choice product. This index is geared to service any commercial program that runs British cross cows.

The Calving Easy Index (CEZ$)

The Calving Easy Index (CEZ$) is a general purpose index that focuses on identifying bulls that can be used on heifers and then ultimately the calves will be marketed through CHB. As you might expect, Calving Ease (CE) and Maternal Calving Ease (MCE) has significant weight in this index along with fertility. There is very little weight put on growth traits and less emphasis on carcass. Remember, this is a general index that is specifically designed to be used in a heifer program.

The Brahman Influence Index (BII$)

The Brahman Influence Index (BII$) is a maternally focused index that is based off of a 1000 head cow herd of Brahman x Hereford cross cows. The progeny for this index will be harvested in a commodity based system since CHB does not allow Brahman influenced cattle into the program. This index has less emphasis for Calving Ease (CE) than any of the other indexes. There is emphasis on both Rib Eye Area (REA) and Marbling (MARB) since the cattle will be harvested through a commodity market. The largest emphasis in this index is in fertility which is measured solely by Scrotal Circumference (SC) at the present time. Obviously, the target for this index is the producers in the Southern regions of the US where the bulls are typically sold to commercial cattlemen that have Brahman Influenced cow herds.

The CHB Index (CHB$)

The CHB Index (CHB$) is a terminal sire index that is built on a production system where Hereford bulls sire calves for the CHB market. There is some pressure put on Calving Ease (CE) and then positive weight on both Weaning Weight (WW) and Yearling Weight (YW). Remember, that all offspring in this index are harvested, so we want them to be born alive and then grow fast at all stages of life. Of course, we have a much heavier weight value on fat in this index, as we want the cattle to stay lean. There is also a significant weight on both Ribeye Area (REA) and Marbling (MARB) with more emphasis again on MARB. This index would be used by producers who have a target of producing bulls for a terminal breeding program. This index could be used heavily in the Midwest where bulls are used in rotational breeding programs to produce cattle in a retained ownership program or simply sold to backgrounders. This is the only index that has no emphasis on fertility. Remember that nothing is retained in the herd.

Trait Leader Tables

There are four trait leader reports available below that provide the top 200 animals of specific classes or types in the Hereford breed based on the $Profit Indexes which use multiple EPD criteria in their calculation. An explanation can be found within each of the reports.

All of these reports can be downloaded for free. The files that you download can then be printed at your home or office or distributed to potential customers, etc. We do have this information available in hard copy form, which can be sent to you upon request. Feel free to contact the AHA customer service department at 816-842-3757 if you would like to order a copy.

Below are links for each of the available reports. Due to the size of some of these files, it could possibly take several minutes for some of these reports to be downloaded to your computer if you are accessing the internet on a dial-up connection. Additionally, you will need a copy of the Adobe Acrobat Reader to view and print these reports. If you do not currently have a copy of the Acrobat Reader, click here to download a free copy of the program.
