The 2016 Feeding the Genes study, conducted by Dr John Morton, for ADHIS, investigated interactions between sire genetics and feeding systems on:
- milk solids production;
- and the cow’s chance of lasting in the herd.
The milk production results were clear. The study found that in all feeding systems, the daughters of high index (BPI, HWI or TWI) sires produce more milk
solids than daughters of low index sires.
In terms of survival, the daughters of high index (BPI, HWI and TWI) sires last longer than daughters of low index sires in all pasture-based feeding systems.
The scale of effects of sire index vary by index and feeding system:
The HWI has larger effects on longevity than BPI or TWI.
In low bail feeding systems the daughters of high BPI and HWI sires last longer than daughters of low index sires.
In moderate to high bail feeding, partial mixed ration (PMR) and hybrid feeding systems, the daughters of high index (BPI, HWI and TWI) sires last longer.
In total mixed ration (TMR) systems the daughters of high HWI sires last longer.
The findings support the take-home message that herd managers should select high index sires whose ABVs are aligned with the breeding objectives for their herd, regardless of their feeding system.

A world-leading smart phone app developed by the ADHIS and Dairy Australia to help farmers choose bulls to meet their breeding objectives is now available to download, free for dairy farmers and advisors.
The Good Bulls app has been designed in close consultation with dairy farmers and advisors and builds on the popular Good Bulls Guide. The app, which can
search from over 20,000 bulls, allows farmers and advisors to search, filter, short list and export bulls based on Australian Breeding Values and Australia’s
ADHIS Extension Officer Sarah Saxton has led the team that helped create the Good Bulls app. She said the app will be an invaluable tool to access bull information anywhere at any time, so farmers can take charge of their herd.
“The Good Bulls app really puts the power of herd improvement in the palm of your hand by giving users on-the-go access to over 20,000 bulls and the ability to enquire about prices with their supplier at the click of a button” Ms Saxton said.
“It’s quick and easy. Select your index and shortlist bulls based on the traits you want to improve in your herd using the Good Bulls app”
The Good Bulls app answers a strong desire by farmers and advisors to be able to filter and sort bulls based on their preferences and to improve profit in a fun and easy way.
Sarah says “We conducted over 20 hours of one on one interviews with a range of farmers and advisors in the design of the app so we are confident this is going to be an essential tool for the industry”.
The Good Bulls app is available for both iPhone and Android phones.

For dairy farmers who plan on spring calving, the next few weeks are a crucial time not only for their herds, but also for their business and profit plans, especially if they are using Artificial Insemination (AI) techniques on-farm.

A new project, ImProving Herds aims to demonstrate how innovative science, on farm testing and data driven decision-making deliver increased profits. To achieve this a collaborative team of Australian and international dairy industry organisations and experts has united to explain existing value and explore future services.
