American Hereford Association (AHA)

There are several ways that American Hereford Association members can interface with CattleMax.

Download & Import Herd Extract

AHA can provide an electronic copy of your herd records, called a herd extract.  This file contains all of your active animals, 3-generation pedigrees, EPDs, and performance data.  A herd extract is a fast and easy way to get up-and-running with CattleMax.

If you are going to be using the AHA TPR program, you will need to contact the Hereford Association and let them know before having us request your herd data file.  Please note that CattleMax will request your herd data from the association.

Contact us and be sure to include your name, ranch name, and AHA membership number(s).  After we receive your herd extract from AHA, we will send the file and detailed instructions on how to import the file and whether or not you need to use the Sync option. NOTE: If importing records, please wait until the import process is complete before entering any records into your CattleMax Online account.

Importing your Herd Inventory Extract

After receiving your herd inventory extract from AHA and CattleMax, you'll need to import the file as noted above. Be sure you have selected American Hereford Association as your CattleMax breed interface - enabling-breed-association-interfaces

Then, go to Cattle/View all groups and interfaces, select American Hereford Association under the Breed Interface header.  That will take you to this screen:

Click/touch the Import Herd Extract button, then select the AHA herd inventory extract file as designated.  If you already have animals in your CattleMax herd file, you'll need to read the Important notes on the sync process to determine if you need to use the Sync option.

Click/touch the Import Herd Extract button to complete the process.

Frequently Asked Questions

Q: What if you have multiple owners that are linked at the AHA? Do they need to be separated in CattleMax?

A: AHA will keep ownership of animals based on the ownership info that is at AHA for the dam. If a new calf is to be multiple-owned by different linked accounts, you will need to communicate this as you email the file to us. Just mention who all should own which animals in the file you are sending.

Q: By emailing the exported file from CattleMax do you get charged the electronic fee for registrations?

A: Yes, if the data is submitted electronically.

Q: AHA is starting the new real time online register data system this year. Is CattleMax tied into the new web site?

A: If you are flagged as a PC user at AHA, you will still get download files created that you can import into CattleMax. You will need to download files from the AHA website and import them into CattleMax.

Q: What is the difference between the initial and final TPR inventories?

A: The initial inventory is the starting point to let you know the animals AHA thinks will be on this season’s inventory. Once you send us your update and AHA processes it, we make available a final inventory file that you can import if you like for confirmation of the animals we have enrolled for you for this particular season.

Q: Where do I save the files I download from the AHA website, so I can import them into CattleMax?

A: Create a folder on your computer desktop where you download all of your files, and as you download them just be sure you direct them to that location. That way when you try to import a file, you know where to go and select it from.

Q: I manually added cattle to my CattleMax inventory – do I include the prefix for the registration number (such as P123456).

A: No prefixes such as “P”, etc. should be entered. Only enter the numeric value, as CattleMax looks for numeric values for the registration number to match updated EPDs, performance data, etc.

Q: How do you request EPD updates from AHA?

A: AHA will make available herd EPD updates on all your animals as each new EPD run is released in December and July. Otherwise, crop EPD updates on specific calf-crops are automatically made available as we process new information on your herd, such as weaning weights, etc. There shouldn’t really be any need to request new EPD updates from AHA.

Q: I am new to the TPR/crop process of AHA. What are the basics of the process?

A: Call the AHA office to go over the basics of how the AHA works. They will explain about tracking performance data via calf-crops and starting with herd inventory updates. They can also let you know your options for recording information with AHA.

Q: How do I indicate to transfer an animal on registration?

A: When sending in your registration file to AHA, simply make a note in the email.

Q: I imported my Crop EPD file and my calf registration numbers did not import.

A: CattleMax will import registration numbers for unregistered calves when importing EPD files. CattleMax matches the unregistered calf to the EPD file based on: Birth Date, Tattoo (Left and/or Right), and Dam Reg Number. If any of this information is incomplete, you will need to complete the information and then re-import the file.

Q: What do the percentage numbers stand for in your CattleMax - AHA Interface?

Form 1: Done is # of cows where calving ease filled in + # of unique dams where their calf's reg number is filled in. Total is # of cows in group.
BW: Done is # of active calves where adj birth weight is filled in. Total is active calves.
WW: Done is # of active calves where adj ww is filled in. Total is active calves.
YW: Done is # of active calves where adj yearling weight is filled in. Total is active calves.
Ultrasound: Done is # of active calves where ultrasound date is filled in. Total is active calves
