Profile of Dairy Futures CRC Heading Invests AUS$20 million p.a. in dairy bioscience Pastures ( ) Cattle + 15 project partners Improvement Now in 6 th year of operation Diversified portfolio of bioscience projects Global partnerships (commercial and research)

Core targets for pasture breeding Heading Yield Persistence Energy

Core targets for pasture breeding Heading One-off increase of +20% through hybrids Ongoing 3X current Yield rate of progress using genomics Persistence Energy

Core targets for pasture breeding Heading Yield Persistence Energy Smart selection of plants: 0.3MJ increase Use of genome editing: +2MJ

Core targets for pasture breeding Heading Yield +1 year: improved endophytes Persistence Energy +2 more years: edited endophytes and better plant-endophyte matching

Why F1 Hybrid Breeding? Heading

What about F1 performance in ryegrass? Heading Parent 1 Parent 2 20% yield increase = $400+/Ha F1 offspring

High Energy Ryegrass (GM) Heading Recent trial of High Energy Ryegrass in a climate controlled chamber – simulating summer growing conditions

Heading 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

Genetics does change milk in the vat!
