  1. 1. NZ Pastoral Industry Conundrum <br />Low cost grazing systems historically our competitive advantage, but these systems:<br /><ul><li>Need inputs - water, nutrients
  2. 2. Are affected by climate extremes (drought, high temperatures)
  3. 3. Contribute to greenhouse gas emissions (methane, nitrous oxide)
  4. 4. Do not have 1000s of years of breeding to improve performance (unlike food crops)</li></li></ul><li>Pastoral Genomics Inc.<br />Formed in 2002<br />Industry-good research consortium between Meat & Wool New Zealand, DairyNZ, Fonterra, AgResearch, DEEResearch and matched funding from FRST<br />Looking specifically at pasture improvements using biotechnology techniques applied to ryegrass and clover<br />
  5. 5. AgResearch Ltd<br />Largest Crown Research Institute<br />Mission is to apply the depth of experience and expertise it has in every aspect of pastoral farming and also in biotechnology to continue to build substantial competitive advantage throughout the value chain. <br />
  6. 6. GM forages could reduce agriculture’s environmental footprint while enhancing productivity<br />APPLIED DISCOVERY AND DEVELOPMENT by PG<br />Improved drought tolerance<br />Increased year-round forage biomass<br />Increased quality of forages (high sugars)<br />APPLIED DISCOVERY forthcoming from PG<br />Nitrogen use efficiency<br />Water use efficiency<br />Phosphorus use efficiency<br />FORAGE IMPROVEMENT THROUGH BIOTECHNOLOGY from AgResearch<br />High energy forage (increased lipids)<br />High digestibility forage (reduced lignin)<br />Tailored forage composition (high sugars)<br />Commercialize<br />Develop<br /> Discover<br />
  7. 7. Raising Energy levels in forage may improve quality and reduce GHGs <br />Why?<br /><ul><li>Energy levels in NZ cultivars are too low, affected by environmental & management factors</li></ul>GM approach:<br /><ul><li>“Master switch” for biosynthesis (target5-7 fold increase)</li></ul>More energy to rumen<br />More protein to mammal<br />Less protein breakdown<br />Less greenhouse gas<br />Less nitrogen in urine<br />More weight and milk<br />High Sugar Grasses<br />
  8. 8. Drought tolerance could increase productivity<br />Why?<br /><ul><li>Drought has severe economic and animal health effects
  9. 9. 4 weeks additional growth in NZ dry periods would extend peak animal production
  10. 10. May also reduce irrigation costs</li></ul>GM approach:<br /><ul><li>Dormant ryegrass gene now switched on by drought</li></li></ul><li>Drought tolerant cisgenic® ryegrass in the Biotron<br />Unimproved<br />Contains our cisgene®<br />Contains our cisgene®<br />Unimproved<br />
  11. 11. Pastoral Genomics Economic Benefit estimate- Input / Output Model<br />Ranges depending on cultivar and adoption rate<br />GDP increase between $75M and $1.5B<br />Household income increase between $25M and $500M<br />Employment increase 500-8000 FTE <br />
  12. 12. First field evaluation: drought-tolerantcisgenic® ryegrass<br />Earliest commercialization<br />
