Parent 1 Parent 2 F1 offspring

What about F1 performance in ryegrass?

20% yield increase = $400+/Ha

How does the CRC have an impact?

Introducing the New Indices

Dairy genomics – a new era

Now 2016 Next

Heading

Now: Genomics introduced in 2012

Holstein and Jersey cattle

• Young genomic sires
• Improve key traits in proven sires
• Discover parentage in any cow
• Predict merit of each cow

(equivalent to 7 lactations)

Heading

Now: Fertility improved

• 1 million new fertility records
• Trait is now more “relevant”
• More bulls now get a fertility ABV

Heading

Now: Feed Saved trait

• New in April 2015
• Breed cattle that require less feed for the same

milk production

Heading

2016: Delivery at end of CRC

‐ Entirely new process for genomics ‐ 6 years of science placed in ADHIS ‐ Large improvement in fertility ‐ Heat tolerance as a new trait

Heading

How will we develop a heat tolerance trait?

Heading

Next: Planned improvements…

‐ Further improvement in reliability (can it reach proven bulls?) ‐ Getting more value from cow genotypes ‐ Health traits ‐ More novel science

Heading Genetics does change milk in the vat!

Income per lactation ($)

Quintiles based on genetic merit for milk production (based on the ASI)

Culling of the bottom 20% would increase income by $176 per cow per lactation
