Registration Data Submission


The following is a brief explanation of the information required to register a Simmental or Simbrah animal. This information should be sent on application forms (Herd Handlers) provided by the Association.


  • The Calf's tattoo: brand and location. This is a permanent identification of up to six characters put on each calf by its owner. You may use over six characters if you have purchased a prefix. No two calves in a herd can have the same brand or tattoo. A letter designating the year the calf was born must be included in the tattoo or brand. The only letters we do not use are I, O, Q and V.
  • The calf's birth date and sex
  • Single or multiple birth code: Please designate the type of birth for this animal. If you have twins TO is twin of the opposite sex and TS is twin of the same sex. Frozen embryos use FE and fresh embryos use ET. There are special DNA typing requirements for the dam and sire of embryo transplant offspring. See ASA Rule and Bylaws.


  • Dam's ASA registration number: This is a unique number assigned by the Association to a dam at the time she was registered. If the dam is not registered with ASA, then a permanent identification-not a name-year of birth and her percentage breeds such as 100 Angus or 1/2 Mix and 1/2 Hereford are required.
  • Sire's ASA registration number: This is a unique number assigned by the Association to the sire at the time he was registered. The sire must be registered in the Simmental or Simbrah herdbook before a calf can be registered.
    Breeders using sires of another breed can register calves as Simmental provided the other breed sire is registered with his breed association and then with ASA and the dam is a registered Simmental.


  • Weaning weights:  The calf's actual weaning weight and date are no longer required for registration; the breeder is encouraged to report this information if they have it. Weaning is recommended between 160 and 250 days of age. For contemporary groups weaning must be taken the same day.
  • Yearling weights: Breeders are encouraged to supply this information if they have it providing they have also reported the weaning weight and date. Yearling is recommended between 330 and 440 days of age. Here again for contemporary groups yearling must be taken the same day for all calves.


  • Signature of the owner: The signature (of an authorized representative) of the person requesting registration verifies the accuracy of the information and gives the Association authority to enter this animal into the Simmental or Simbrah herdbook.
  • Signature of the breeder: The breeder's name and signature (of an authorized representative), if different than the person registering the calf, are required. The breeder is the person who owned the dam at the time she was bred. If breeding or calf at side information was supplied at the time of transferring the dam, the breeder's signature is not required on the herd handler application. If the calf is the result of an embryo and the breeder is not the applicant then the calf has to be parentage verified by DNA analysis. 
  • Requesting registration: A registration certificate will be issued if a check is placed in the registration column on the far, right-hand side of the form. By placing a "T" instead of a check, you may request to register and transfer this animal. The buyer's name, address and date of sale must be filled in on the application below the calf's information. 
  • Naming the calf: Now is the time to report a name for the calf keeping in mind you are allowed to use twenty-four characters including spaces. Names should be letters only characters not eligible for use within an animals name are, ", ',?, ,,@, #, ^, *, (), +, =,;,:,!, %, $, <, >. Also, if you are using a prefix it has to be available and approved, there is a $10.00 fee to purchase a prefix.


  • Self-billing worksheets: These worksheets are available to help determine the correct fees. Since ASA operates on a cash basis, processing can not be completed until payment is received; we do accept Visa and Master cards. The performance calculation fee will be charged on all calves you are submitting for the first time unless you r eport the calf as being dead.


  • Performance calculations: The registration application is also a form that is used to supply herd performance records. Breeders are encouraged to list data on all calves in the herd, not just the ones to be registered. By reporting information on all calves born (steers, heifers and bulls) a breeder can get a better picture of the performance of his herd, is more likely to qualify for the cow award program and contributes to ASA's breed-wide evaluation system. The ASA performance registry system automatically calculates adjusted weights, within herd ratios and Expected Progeny Differences (EPDs) on all animals submitted.
