Bull Proving Committee

Coordinator - Sean Tomkins

The Bull Proving Committee is comprised of 5 members of the Guernsey Cattle Society of Australia Inc with one member elected as the committee co-ordinator. The objectives of the committee are to select young bulls to be used in the AI industry, identify cows with potential to be bull mothers and to promote the use of young sires. 

The committee is currently working with Agri-Gene to supply young Australian bulls to Australia and also the overseas Guernsey population where possible. Bulls that have gone through this program include Marglyn Action Mervyn, Sunny Valley Levi Bradman, Gilbert Trademark, Riverton Galaxy, Brookleigh Geo Bruce and Gilbert Bellman. The current young sire available is Triple J Latimar Hulk.

If you have any suggestions for the committee or animals that may be suitable to either enter the young sire program or be used as bull mothers then please contact Sean Tomkins on 0458 049 805 or email alembry75@gmail.com
