Registered Holsteins perform strongly in May proof run

Registered Holsteins performed strongly in the May proof run with representatives of some established and emerging cow families from seven different breeders filling the top 20 new genomic females list.

The rate of genetic gain of the Holstein breed in Australia can also be seen by comparing this month’s proof run to the June 2019 run. The average BPI across the top 20 new animals with a genomic breeding value in June 2019 was 315 BPI compared to 334 BPI for the current month.

Topping the new genomic females list was Emu Banks Holsteins with Emu Banks Perseus Andrea 11405 (371 BPI) who also went straight into the top 20 genomic females list at number 14 overall. Emu Banks Perseus Andrea 11405 was one of six animals from this breeder in the top 20 new genomic females.

Tracing back the Andrea family - prominent at Hill Valley Holsteins - this very much Emu Banks product is the result of a whole herd approach to breeding says Emu Banks’ Bryan Dickson.

“While it's pleasing to have high ones we are all about the average of the herd and for that matter that is why some of the other Emu Banks heifers on that list are just as pleasing. They come from a spread of cow families and sires. It’s great to see how the whole herd is moving forward,” says Bryan.

Gippsland’s Dilee Holsteins was well represented with Dilee Fondoo Nancy 419 (352 BPI) and Dilee Lord 426 (347 BPI) next up on this list, with Dilee Fondoo Ollie 401 (328 BPI) at number 13.

“We have a lot of good Ollie’s and they are performing really well but it’s always good to see results coming out of other cow families and this – Dilee Fondoo Nancy – is one of those. At 352 she is a bit above her parentage average.”

Daybreaker Jeronimo Tiffany (342 BPI) came in at number 6 on the new genomic females list, with breeder Peter Fullerton very pleased at the way his Tiffany’s are performing on genomics.

“For us they’ve been really solid cows. They come in, produce well and maintain body condition. That allows their production to bounce back after a feed pinch,” says Peter.

The top 20 genomic females since 31-12-17 saw a change around in the second and third animals, with Wilara Jeronimo Lollie showing an increase of 15 BPI points month-on-month to 398 BPI and moving up to second position, with Illawambra Lawson Dallas 3914 (394 BPI) now at position three. Remaining at the top of this list is Vala Bandares Boliana (402 BPI).

Ivyhurst Wrangler Mystery 6194 (433 BPI) remains at number one on the top genomic females list with a seven point BPI increase for Purnim Moneyman Shasnah CS4524 (403 BPI) seeing her move from sixth position in April to number two overall. Vala Bandares Boliana-ET (402 BPI) remains at number three.
