AI Approved Sires

ALCA provides a service of registering semen collected from certain Australian Lowline bulls. These bulls are then referred to as AI Approved Sires.

The listing of AI Approved Sires facilitates the registration of progeny from these bulls (refer to By-Law 6.2)

The conditions governing the process for gaining AI Sire Registration and the AI Approved Sires Listing  are set out in By-Law 7.6
A copy of the By-Laws can be accessed here.


  • only an ALCA member is able to apply for a Lowline bull to become an AI Approved Sire
  • all applications require the lodgement of the completed  AI Sires Application Form , to have been SNP tested, payment of the recommended fee, and Council approval

Heritage Semen

This term refers to semen which has been donated to the Association, in the interest of preserving these genetics for future breeders. All semen is from AI Approved Sires, some of which date back to the early days of the Association.
The main objectives of this program are:

  • To maintain heritage genetics that might otherwise be lost
  • To preserve and maximise genetic diversity
  • To provide a repository for semen as members retire and wish to donate to ALCA
  • To provide cost effective semen to members and non-members for AI procedures to promote the Lowline breed

Please refer to ALCA Heritage Semen Guidelines for further information and conditions of the program.
