The latest Australian Breeding Value release has popular polled Holstein bull ABS Jeronimo crowned the new number one Holstein proven sire.

The former number one genomic young sire is joined by Jersey bull Wilsonview IF Matt and Aussie Red sire Onstad P as the top proven sires of their respective breeds.

Australian proven sires

From the ABS stable, Jeronimo (29HO18698) tops the list with a Balanced Performance Index (BPI) of 525.

This popular, polled A2 sire has several high-quality sons available from various suppliers.

Another ABS sire to debut at number two on the proven sire list is De-Su Wrigley (29HO18726) with a BPI of 506 and has solid ratings for protein and overall type.

The Semex sire Westcoast Perseus is another former high ranking genomic sire to deliver on his genomic promise.

With thousands of milking daughters around the world and now with 95 per cent reliability for production in Australia, the influence of Perseus and his sons will continue for some time to come.

Young genomic bulls

Seven major semen suppliers have young bulls with a BPI above 500, demonstrating the intense competition at the pointy end of this list.

TommyDee tops the list with a BPI of 558.

The Australian-bred sire is from the herd of John and Vicki Lillico of Tasmania, and is the son of another high-ranking young bull in EndGame.

TommyDee is also strong for HWI with solid ratings for survival, mastitis resistance and fertility.

TommyDee is available at Genetics Australia.

Second on the list is Westcoast Reverso (0200HO11386) at 525 BPI.

Red dairy breeds

The Red dairy breed group genomic ABVs for four traits - milk, fat, protein and cell count - have been combined with conventional ABVs to provide Red enthusiasts with enhanced BPI, HWI and ASI indexes.

Norwegian sire Onstad P is the top proven Aussie Red sire.

Available through ABS, this polled sire will have a positive impact on the breed into the future with his strong ratings for type and fertility.
